IDNameDescription
CWE-1004Sensitive Cookie Without 'HttpOnly' FlagThis vulnerability occurs when an application stores sensitive data in a cookie but fails to set the 'HttpOnly' flag, leaving the cookie accessible to client-side scripts.
CWE-1007Insufficient Visual Distinction of Homoglyphs Presented to UserThis vulnerability occurs when an application shows text or symbols to users without clearly distinguishing between characters that look identical or very similar (called homoglyphs). Because users can't easily tell these characters apart, they might misinterpret information and accidentally perform unsafe actions, like clicking a malicious link.
CWE-102Struts: Duplicate Validation FormsThis vulnerability occurs when an application defines multiple Struts validation forms with identical names. The framework then unpredictably selects only one form for validation, potentially bypassing intended security checks.
CWE-1021Improper Restriction of Rendered UI Layers or FramesThis vulnerability occurs when a web application fails to properly control whether its pages can be embedded within frames or UI layers from other websites, potentially misleading users about which site they are interacting with.
CWE-1022Use of Web Link to Untrusted Target with window.opener AccessThis vulnerability occurs when a web application links to an external, untrusted site without protecting its own window from being manipulated by that site. Specifically, it fails to prevent the external page from altering security-sensitive properties of the `window.opener` object, such as the page's location.
CWE-1023Incomplete Comparison with Missing FactorsThis weakness occurs when a program compares two items but fails to check all the necessary attributes that define their true relationship. The incomplete check can cause the software to treat different items as identical or make incorrect security decisions.
CWE-1024Comparison of Incompatible TypesThis vulnerability occurs when code directly compares two values of fundamentally different data types, which can lead to unreliable or incorrect results because the comparison logic doesn't handle the type mismatch properly.
CWE-1025Comparison Using Wrong FactorsThis weakness occurs when a program compares two items but checks the wrong properties or attributes. This flawed comparison leads to incorrect decisions, creating security and logic errors.
CWE-103Struts: Incomplete validate() Method DefinitionThis vulnerability occurs in a Struts application when a validator form either completely omits a validate() method or includes one but fails to call super.validate() within it.
CWE-1037Processor Optimization Removal or Modification of Security-critical CodeThis vulnerability occurs when a processor's performance optimization unintentionally strips out or alters security-critical code that a developer intentionally placed in the software.
CWE-1038Insecure Automated OptimizationsThis vulnerability occurs when software uses automated tools to optimize code for performance or efficiency, but those optimizations accidentally weaken or bypass critical security protections that the original code relied upon.
CWE-1039Inadequate Detection or Handling of Adversarial Input Perturbations in Automated Recognition MechanismThis vulnerability occurs when a system uses automated AI or machine learning to classify complex inputs like images, audio, or text, but fails to correctly identify or process inputs that have been deliberately altered. Attackers can exploit this by crafting subtle modifications that cause the system to misclassify the input, leading to incorrect and potentially harmful decisions.
CWE-104Struts: Form Bean Does Not Extend Validation ClassThis vulnerability occurs in Apache Struts applications when a form bean class does not properly extend the framework's validation class. This bypasses the built-in Validator framework, leaving the application without structured input validation and open to various injection and data manipulation attacks.
CWE-1041Use of Redundant CodeThis weakness occurs when a codebase contains identical or nearly identical logic duplicated across multiple functions, methods, or modules. This redundancy creates unnecessary complexity and maintenance overhead.
CWE-1042Static Member Data Element outside of a Singleton Class ElementThis weakness occurs when a class that isn't designed as a singleton (a class meant to have only one instance) contains a non-final static member variable. This creates a shared, mutable state across all instances of that class, which can lead to unexpected behavior and data corruption.
CWE-1043Data Element Aggregating an Excessively Large Number of Non-Primitive ElementsThis weakness occurs when a data structure, like a class or object, contains too many complex sub-elements (e.g., other objects or structs) instead of simple primitive types.
CWE-1044Architecture with Number of Horizontal Layers Outside of Expected RangeThis occurs when a software system is built with either too many or too few distinct architectural layers, falling outside a recommended range that supports maintainability and security.
CWE-1045Parent Class with a Virtual Destructor and a Child Class without a Virtual DestructorThis occurs when a base class defines a virtual destructor, but a derived class inherits from it without declaring its own virtual destructor.
CWE-1046Creation of Immutable Text Using String ConcatenationThis weakness occurs when code builds a string within a loop using simple concatenation (like +=), which unintentionally creates new string objects every time instead of efficiently appending to a buffer.
CWE-1047Modules with Circular DependenciesThis weakness occurs when software modules have circular references, meaning Module A depends on Module B, which in turn depends back on Module A, creating a closed loop.
CWE-1048Invokable Control Element with Large Number of Outward CallsThis weakness occurs when a single function, method, or callable code block makes an excessively high number of calls to other objects or components outside its immediate scope. This creates a complex, tightly-coupled web of dependencies that is difficult to manage.
CWE-1049Excessive Data Query Operations in a Large Data TableThis weakness occurs when an application runs a database query that uses numerous joins and sub-queries on a very large table, leading to severe performance degradation.
CWE-105Struts: Form Field Without ValidatorThis vulnerability occurs when a Struts application form contains an input field that lacks a corresponding validator, leaving it open to unverified user input.
CWE-1050Excessive Platform Resource Consumption within a LoopThis vulnerability occurs when a loop contains code that repeatedly consumes critical system resources like file handles, database connections, memory, or session locks. Each iteration of the loop drains these finite platform assets without proper release.
CWE-1051Initialization with Hard-Coded Network Resource Configuration DataThis vulnerability occurs when software uses fixed, hard-coded values—like IP addresses, domain names, or URLs—to identify network resources during its startup or configuration phase.
CWE-1052Excessive Use of Hard-Coded Literals in InitializationThis weakness occurs when software initializes variables or data structures using hard-coded values (like strings, file paths, or network addresses) instead of configurable constants or parameters. While simple numbers or true constants are acceptable, embedding non-trivial literals directly in code creates maintenance and security risks.
CWE-1053Missing Documentation for DesignThis weakness occurs when software lacks clear design documentation, making it difficult to understand how the system is structured and intended to work.
CWE-1054Invocation of a Control Element at an Unnecessarily Deep Horizontal LayerThis weakness occurs when code in one architectural layer directly calls functions or methods in a much deeper layer, skipping over the intermediate layers that should normally handle the request. It bypasses the intended layered structure, similar to a manager going directly to an intern instead of working through the team lead.
CWE-1055Multiple Inheritance from Concrete ClassesThis weakness occurs when a single class inherits functionality and state from more than one concrete (fully implemented) parent class.
CWE-1056Invokable Control Element with Variadic ParametersThis weakness occurs when a callable function or method is defined to accept a variable number of arguments (variadic parameters).
CWE-1057Data Access Operations Outside of Expected Data Manager ComponentThis weakness occurs when an application bypasses its dedicated, central data manager component and performs data access operations through other code paths.
CWE-1058Invokable Control Element in Multi-Thread Context with non-Final Static Storable or Member ElementThis happens when a method or function, designed to run in a multi-threaded environment, accesses or modifies a non-final static variable or class member. Because the static element is not final, its state can be changed unexpectedly by concurrent threads, leading to race conditions and unpredictable behavior.
CWE-1059Insufficient Technical DocumentationThis weakness occurs when a software or hardware product lacks comprehensive technical documentation. Missing or incomplete details about the system's architecture, interfaces, design, configuration, or operation make it difficult to understand, maintain, and secure the product effectively.
CWE-106Struts: Plug-in Framework not in UseThis weakness occurs when a Java application, particularly one using the Struts framework, does not implement a structured input validation plugin like the Struts Validator. Skipping this framework forces developers to write custom validation logic, which is often error-prone and increases the risk of security flaws from improperly handled user input.
CWE-1060Excessive Number of Inefficient Server-Side Data AccessesThis weakness occurs when an application makes an excessive number of individual data queries to a server or database, instead of using more efficient methods like stored procedures or batch operations.
CWE-1061Insufficient EncapsulationThis weakness occurs when a software component exposes too much of its internal workings, such as data structures or implementation logic. This lack of proper boundaries allows other parts of the system to interact with it in unintended ways, potentially leading to corrupted data, unexpected behavior, or hidden dependencies.
CWE-1062Parent Class with References to Child ClassThis weakness occurs when a parent class directly references its child classes, their methods, or their member variables, creating a problematic and tightly coupled dependency.
CWE-1063Creation of Class Instance within a Static Code BlockThis weakness occurs when a class instance is created inside a static initializer block, causing premature and potentially expensive object creation.
CWE-1064Invokable Control Element with Signature Containing an Excessive Number of ParametersThis weakness occurs when a function, method, or subroutine is defined with an unnecessarily high number of parameters in its signature.
CWE-1065Runtime Resource Management Control Element in a Component Built to Run on Application ServersThis weakness occurs when an application built to run on a managed application server bypasses the server's high-level APIs and instead uses low-level operating system calls to directly control resources like memory, files, or threads.
CWE-1066Missing Serialization Control ElementThis weakness occurs when a class or data structure is marked as serializable but lacks the required control methods to properly handle the serialization and deserialization process.
CWE-1067Excessive Execution of Sequential Searches of Data ResourceThis weakness occurs when a database query is structured in a way that forces the system to scan entire tables row-by-row, instead of using an available index for efficient lookups.
CWE-1068Inconsistency Between Implementation and Documented DesignThis weakness occurs when the actual code implementation deviates from the intended design described in its official documentation, creating a mismatch between how the system is supposed to work and how it actually does.
CWE-1069Empty Exception BlockThis weakness occurs when a try-catch or try-finally block is present but contains no code to handle the caught exception or perform cleanup.
CWE-107Struts: Unused Validation FormThis vulnerability occurs when a Struts application contains validation form definitions that are no longer linked to any active form or action, leaving outdated security rules in the codebase.
CWE-1070Serializable Data Element Containing non-Serializable Item ElementsThis weakness occurs when a class or data structure is marked as serializable, but it contains one or more member elements that cannot be serialized. This mismatch prevents the entire object from being properly saved or transmitted.
CWE-1071Empty Code BlockAn empty code block occurs when a section of source code, such as a conditional statement or function body, contains no executable statements.
CWE-1072Data Resource Access without Use of Connection PoolingThis weakness occurs when an application creates a new database connection for every request instead of using a managed connection pool. This inefficient pattern forces the system to repeatedly endure the full overhead of establishing and tearing down connections.
CWE-1073Non-SQL Invokable Control Element with Excessive Number of Data Resource AccessesThis weakness occurs when a client-side function or method makes an excessive number of individual data requests through a non-SQL data manager, instead of using more efficient bulk operations or database-native capabilities.
CWE-1074Class with Excessively Deep InheritanceThis weakness occurs when a class inherits from an excessive number of parent classes, creating a deep and complex inheritance hierarchy.
CWE-1075Unconditional Control Flow Transfer outside of Switch BlockThis weakness occurs when code uses an unconditional jump, like a 'goto' statement, outside of a structured control flow block like a switch statement. This bypasses the intended logic and makes the program's execution path unpredictable and difficult to follow.
CWE-1076Insufficient Adherence to Expected ConventionsThis weakness occurs when software code, design, documentation, or other components fail to follow established industry or project-specific standards and conventions.
CWE-1077Floating Point Comparison with Incorrect OperatorThis vulnerability occurs when code compares two floating-point numbers using direct equality operators (like == or !=) without accounting for inherent precision limitations. These operators fail to consider tiny rounding differences that are common in floating-point arithmetic, leading to incorrect or unexpected comparison results.
CWE-1078Inappropriate Source Code Style or FormattingThis weakness occurs when source code violates established style guidelines for formatting, indentation, whitespace, or commenting, making it difficult to read and maintain.
CWE-1079Parent Class without Virtual Destructor MethodThis occurs when a base class, designed to be inherited from, does not declare its destructor as virtual. This oversight prevents proper cleanup when objects are deleted through a pointer to the parent class.
CWE-108Struts: Unvalidated Action FormIn Apache Struts, every Action Form that processes user input must have a corresponding validation form configured. Missing this validation exposes the application to unvalidated data.
CWE-1080Source Code File with Excessive Number of Lines of CodeThis weakness occurs when a single source code file grows excessively large, containing too many lines of code.
CWE-1082Class Instance Self Destruction Control ElementThis vulnerability occurs when an object's code contains logic that triggers its own deletion or destruction during runtime.
CWE-1083Data Access from Outside Expected Data Manager ComponentThis weakness occurs when an application is designed to handle all data operations through a dedicated manager component (like a database layer), but code elsewhere bypasses it and accesses data directly.
CWE-1084Invokable Control Element with Excessive File or Data Access OperationsThis weakness occurs when a single function or method performs an excessive number of file or database operations, such as repeated reads, writes, or queries. It over-relies on a single data manager or file resource, creating a tightly coupled and fragile code structure.
CWE-1085Invokable Control Element with Excessive Volume of Commented-out CodeThis weakness occurs when a callable function, method, or procedure contains a large amount of inactive, commented-out code within its implementation body.
CWE-1086Class with Excessive Number of Child ClassesThis weakness occurs when a parent class has an excessive number of child classes that inherit from it, creating a deep and overly complex inheritance tree.
CWE-1087Class with Virtual Method without a Virtual DestructorThis occurs when a class defines a virtual method but does not also provide a virtual destructor.
CWE-1088Synchronous Access of Remote Resource without TimeoutThis vulnerability occurs when an application makes a synchronous call to a remote service or resource but does not set a timeout, or sets an infinite one. This leaves the application waiting indefinitely for a response.
CWE-1089Large Data Table with Excessive Number of IndicesThis weakness occurs when an application uses a database table with a very large number of rows and creates too many indexes on it, degrading overall system performance.
CWE-109Struts: Validator Turned OffThis vulnerability occurs when an application built with Apache Struts intentionally disables its built-in validation framework. By turning off the Struts Validator bean, developers remove critical automatic input filtering and custom validation rules, leaving the application unprotected against malicious or malformed data.
CWE-1090Method Containing Access of a Member Element from Another ClassThis weakness occurs when a method in one class directly accesses a private or internal member (like a field or property) of a different class, bypassing proper interfaces.
CWE-1091Use of Object without Invoking Destructor MethodThis weakness occurs when a program accesses an object but fails to properly call its destructor or finalizer method. This leaves the cleanup of the object's resources to the system's automatic garbage collection, which may not happen immediately or predictably.
CWE-1092Use of Same Invokable Control Element in Multiple Architectural LayersThis weakness occurs when the same piece of code or control logic is duplicated across different architectural layers of an application, such as the presentation, business, and data layers.
CWE-1093Excessively Complex Data RepresentationThis weakness occurs when software uses an overly complicated internal model to represent its data or the relationships between data elements.
CWE-1094Excessive Index Range Scan for a Data ResourceThis weakness occurs when a database query performs an index range scan that can access an unnecessarily large number of rows from a substantial data table, leading to severe performance degradation.
CWE-1095Loop Condition Value Update within the LoopThis vulnerability occurs when a loop's exit condition depends on a variable that is also modified inside the loop body. This creates a complex and often unpredictable control flow that is difficult to analyze.
CWE-1096Singleton Class Instance Creation without Proper Locking or SynchronizationThis flaw occurs when a Singleton class is implemented without proper thread-safe controls, allowing multiple instances to be created in concurrent environments.
CWE-1097Persistent Storable Data Element without Associated Comparison Control ElementThis weakness occurs when a persistent data object lacks the necessary methods to be properly compared, which can lead to inconsistent or incorrect behavior when the system checks for equality or manages collections.
CWE-1098Data Element containing Pointer Item without Proper Copy Control ElementThis weakness occurs when a data structure contains a pointer, but the code lacks proper methods to copy or initialize that pointer safely.
CWE-1099Inconsistent Naming Conventions for IdentifiersThis weakness occurs when a codebase uses mixed naming styles for elements like variables, functions, data types, or files, creating an inconsistent and confusing structure.
CWE-11ASP.NET Misconfiguration: Creating Debug BinaryDeploying an ASP.NET application with debug binaries enabled exposes detailed system information, which attackers can use to map your infrastructure and plan targeted exploits.
CWE-110Struts: Validator Without Form FieldThis vulnerability occurs when a Struts application's validation configuration file references form fields that no longer exist in the corresponding ActionForm class. This mismatch indicates outdated validation logic that can fail to properly check user input.
CWE-1100Insufficient Isolation of System-Dependent FunctionsThis weakness occurs when an application fails to separate its core logic from functions that depend on a specific operating system, hardware, or external platform. Instead of being contained in dedicated modules, these system-dependent calls are scattered throughout the codebase.
CWE-1101Reliance on Runtime Component in Generated CodeThis vulnerability occurs when software depends on automatically generated code that requires a specific, often external, runtime component to function. Without this component, the code cannot execute, creating a fragile and non-portable foundation.
CWE-1102Reliance on Machine-Dependent Data RepresentationThis weakness occurs when software directly depends on how a specific machine, processor, or operating system represents data in memory. Code that makes assumptions about byte order, data type sizes, or memory alignment becomes fragile and non-portable.
CWE-1103Use of Platform-Dependent Third Party ComponentsThis weakness occurs when software depends on third-party libraries or components that behave differently or lack support across various target platforms or operating systems.
CWE-1104Use of Unmaintained Third Party ComponentsThis weakness occurs when software depends on third-party libraries, frameworks, or modules that are no longer actively updated or supported by their creators or a trusted maintainer.
CWE-1105Insufficient Encapsulation of Machine-Dependent FunctionalityThis weakness occurs when an application relies on hardware-specific or platform-dependent features but fails to isolate that code from the rest of the system. This poor separation creates tight coupling between the core logic and low-level machine details.
CWE-1106Insufficient Use of Symbolic ConstantsThis weakness occurs when developers embed raw numbers or text strings directly in code instead of using named symbolic constants, making future updates and maintenance more difficult.
CWE-1107Insufficient Isolation of Symbolic Constant DefinitionsThis weakness occurs when a codebase uses symbolic constants (like named values for numbers or strings) but scatters their definitions across many files instead of centralizing them in one isolated location, such as a dedicated configuration file or module.
CWE-1108Excessive Reliance on Global VariablesThis weakness occurs when a codebase depends too heavily on global variables to store and manage state, rather than keeping data within appropriate local scopes like functions or classes.
CWE-1109Use of Same Variable for Multiple PurposesThis weakness occurs when a single variable is reused to handle multiple, unrelated tasks or to store different pieces of data throughout the code. This practice muddies the variable's purpose and makes the logic harder to follow.
CWE-111Direct Use of Unsafe JNIThis weakness occurs when a Java application directly calls native code through the Java Native Interface (JNI), exposing the entire application to security risks present in that external code, even if Java itself is safe from those specific flaws.
CWE-1110Incomplete Design DocumentationThis vulnerability occurs when a system's design documentation is missing critical details about how the software actually works. Key omissions include unclear control flow, undefined data movement, missing system startup procedures, vague component relationships, or unexplained design decisions.
CWE-1111Incomplete I/O DocumentationThis weakness occurs when a product's documentation fails to clearly and completely define its inputs, outputs, or how it interacts with other systems or software components.
CWE-1112Incomplete Documentation of Program ExecutionThis weakness occurs when a system's documentation fails to completely list all the ways its behavior can be controlled or changed during execution.
CWE-1113Inappropriate Comment StyleThis weakness occurs when source code comments are written in a style or format that doesn't match the project's established standards or common conventions for the language.
CWE-1114Inappropriate Whitespace StyleThis weakness occurs when source code uses inconsistent or non-standard whitespace formatting, such as irregular indentation, spacing, or line breaks.
CWE-1115Source Code Element without Standard PrologueThis weakness occurs when source code files or modules lack a consistent, standardized header or prologue that the development team has agreed upon.
CWE-1116Inaccurate CommentsThis weakness occurs when code comments do not correctly describe or explain the actual behavior of the associated code. Misleading comments create a disconnect between what the documentation says and what the program actually does.
CWE-1117Callable with Insufficient Behavioral SummaryThis weakness occurs when a function, method, or API lacks clear documentation about its behavior. The signature or comments fail to properly explain what inputs it expects, what outputs it returns, what side effects it causes, or what assumptions it makes.
CWE-1118Insufficient Documentation of Error Handling TechniquesThis weakness occurs when software documentation fails to clearly explain how the system manages errors, exceptions, or unexpected conditions. Developers are left guessing about the proper handling mechanisms.
CWE-1119Excessive Use of Unconditional BranchingThis weakness occurs when code relies heavily on unconditional jumps like 'goto' statements, making the program flow difficult to follow.
CWE-112Missing XML ValidationThis vulnerability occurs when an application processes XML data from an untrusted source without first validating its structure and content against a defined schema.
CWE-1120Excessive Code ComplexityThis weakness occurs when software contains sections of code that are unnecessarily intricate, as measured by established complexity metrics like cyclomatic complexity or cognitive load scores.
CWE-1121Excessive McCabe Cyclomatic ComplexityThis weakness occurs when a function or method has an overly complex control flow, measured by a high McCabe Cyclomatic Complexity score. This makes the code difficult to read, test, and maintain.
CWE-1122Excessive Halstead ComplexityThis weakness occurs when code has an excessively high Halstead complexity score, indicating it is overly intricate and difficult to analyze.
CWE-1123Excessive Use of Self-Modifying CodeThe software relies heavily on code that rewrites itself during execution, making it difficult to analyze and maintain.
CWE-1124Excessively Deep NestingThis weakness occurs when a function, method, or code block contains too many levels of nested loops, conditionals, or other control structures, making the logic path difficult to follow.
CWE-1125Excessive Attack SurfaceThis weakness occurs when a software product has an unnecessarily large number of entry and exit points that an attacker can target, exceeding a reasonable and secure threshold.
CWE-1126Declaration of Variable with Unnecessarily Wide ScopeThis weakness occurs when a variable is declared with a broader scope than it actually needs, such as declaring a variable at a global or function level when it's only used inside a loop or conditional block.
CWE-1127Compilation with Insufficient Warnings or ErrorsThis weakness occurs when source code is compiled without enabling a comprehensive set of warning flags from the compiler. This practice allows subtle bugs, insecure coding patterns, and quality issues to go undetected during the build process.
CWE-113Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Request/Response Splitting')This vulnerability occurs when an application accepts user-supplied data and includes it directly in HTTP headers without properly filtering out carriage return (CR) and line feed (LF) characters. This allows an attacker to inject new headers or split a single HTTP response into two separate responses, corrupting the intended communication flow.
CWE-114Process ControlProcess Control vulnerabilities occur when an application executes commands or loads libraries from an untrusted source or environment, allowing an attacker to run malicious code.
CWE-115Misinterpretation of InputThis vulnerability occurs when software incorrectly interprets or processes input data, leading to unintended and potentially harmful security consequences. The flawed interpretation can come from user-provided data, external systems, or other components.
CWE-116Improper Encoding or Escaping of OutputThis vulnerability occurs when an application builds a structured message—like a query, command, or request—for another component but fails to properly encode or escape user-supplied data. Because the output's structure isn't preserved, an attacker can inject malicious instructions that the receiving component will execute.
CWE-1164Irrelevant CodeIrrelevant code refers to sections of a program that have no impact on its execution, data, or logic. Removing this code would not change the software's behavior or correctness, as it performs no meaningful operations.
CWE-117Improper Output Neutralization for LogsThis vulnerability occurs when an application creates log entries using unvalidated external data, allowing attackers to inject malicious characters or commands that can corrupt log files, trigger parsing errors, or enable log injection attacks.
CWE-1173Improper Use of Validation FrameworkThis vulnerability occurs when a software application either fails to use or incorrectly implements a built-in or library-provided input validation framework.
CWE-1174ASP.NET Misconfiguration: Improper Model ValidationThis vulnerability occurs when an ASP.NET application either completely bypasses the built-in model validation system or implements it incorrectly, allowing untrusted data to flow into the application without proper checks.
CWE-1176Inefficient CPU ComputationThis weakness occurs when software uses inefficient algorithms or suboptimal CPU operations, performing unnecessary or overly complex calculations that waste processing power and slow down performance.
CWE-1177Use of Prohibited CodeThis vulnerability occurs when software incorporates a function, library, or third-party component that has been explicitly banned by the development team or the customer.
CWE-118Incorrect Access of Indexable Resource ('Range Error')This vulnerability occurs when software fails to properly check the boundaries of an indexed resource, like an array, buffer, or file, before accessing it. This allows reading from or writing to memory locations outside the intended range.
CWE-1187DEPRECATED: Use of Uninitialized ResourceThis entry has been consolidated into CWE-908: Use of Uninitialized Resource. All relevant information has been migrated to that primary weakness entry.
CWE-1188Initialization of a Resource with an Insecure DefaultThis vulnerability occurs when software uses an insecure default setting or value for a resource, assuming an administrator will change it later.
CWE-1189Improper Isolation of Shared Resources on System-on-a-Chip (SoC)This vulnerability occurs when a System-on-a-Chip (SoC) fails to properly separate shared hardware resources between secure (trusted) and non-secure (untrusted) components.
CWE-119Improper Restriction of Operations within the Bounds of a Memory BufferThis vulnerability occurs when software accesses a memory buffer but reads from or writes to a location outside its allocated boundary. This can corrupt adjacent data, crash the program, or allow attackers to execute arbitrary code.
CWE-1190DMA Device Enabled Too Early in Boot PhaseThis vulnerability occurs when a device with Direct Memory Access (DMA) capability is activated before the system's security settings are fully locked in during the boot process. This oversight can let an attacker bypass normal protections to read sensitive data from memory or escalate their privileges on the system.
CWE-1191On-Chip Debug and Test Interface With Improper Access ControlThis vulnerability occurs when a hardware chip's debug or test interface (like JTAG) lacks proper access controls. Without correct authorization checks, unauthorized users can read or modify sensitive internal registers and bypass the chip's built-in security protections.
CWE-1192Improper Identifier for IP Block used in System-On-Chip (SOC)This weakness occurs when a System-on-Chip (SoC) lacks a secure, unique, and permanent identifier for its internal hardware components (IP blocks). Without this, the system cannot reliably distinguish between different parts of the chip, leading to security and reliability failures.
CWE-1193Power-On of Untrusted Execution Core Before Enabling Fabric Access ControlThis vulnerability occurs when a system powers up hardware components containing untrusted firmware before establishing critical security controls for the system's internal communication pathways and memory.
CWE-12ASP.NET Misconfiguration: Missing Custom Error PageThis vulnerability occurs when an ASP.NET application fails to configure custom error pages, allowing attackers to extract sensitive information from the framework's default error messages.
CWE-120Buffer Copy without Checking Size of Input ('Classic Buffer Overflow')This vulnerability occurs when a program copies data from one memory location to another without first verifying that the source data will fit within the destination buffer's allocated space.
CWE-1204Generation of Weak Initialization Vector (IV)This vulnerability occurs when software uses a weak or predictable Initialization Vector (IV) for cryptographic operations. Many encryption algorithms require IVs to be both unique and unpredictable to ensure security, and failing to meet these requirements can compromise the entire encryption process.
CWE-1209Failure to Disable Reserved BitsThis vulnerability occurs when reserved bits in a hardware design are left active in production. Designers sometimes use these bits for debugging or future features, but if not disabled, attackers can manipulate them to compromise the hardware's state.
CWE-121Stack-based Buffer OverflowA stack-based buffer overflow occurs when a program writes more data to a buffer located on the call stack than it can hold, corrupting adjacent memory and potentially hijacking the program's execution flow.
CWE-122Heap-based Buffer OverflowA heap-based buffer overflow occurs when a program writes more data to a memory buffer allocated in the heap than it can hold, corrupting adjacent memory structures. This typically involves buffers created with functions like malloc(), calloc(), or realloc().
CWE-1220Insufficient Granularity of Access ControlThis vulnerability occurs when a system's access controls are too broad, allowing unauthorized users or processes to read or modify sensitive resources. Instead of implementing precise, fine-grained permissions, the security policy uses overly permissive rules that fail to properly restrict access to critical assets like configuration data, keys, or system registers.
CWE-1221Incorrect Register Defaults or Module ParametersThis vulnerability occurs when hardware description language (HDL) code sets insecure default values for hardware registers or configurable module parameters. These hardcoded values leave the hardware in an unsafe state after a reset, creating a permanent security weakness that software cannot patch.
CWE-1222Insufficient Granularity of Address Regions Protected by Register LocksThis vulnerability occurs when a hardware design uses a single lock bit to protect a large, coarse block of memory addresses. This lack of granularity creates a conflict: the system needs to lock critical configuration settings early for security, but software also needs to write to other parts of that same address region during normal operation, which the lock incorrectly prevents.
CWE-1223Race Condition for Write-Once AttributesThis vulnerability occurs when an untrusted software component wins a race condition and writes to a hardware register before the trusted component can, permanently locking in an insecure value because the register is designed to be written only once.
CWE-1224Improper Restriction of Write-Once Bit FieldsThis vulnerability occurs when hardware write-once protection mechanisms, often called 'sticky bits,' are incorrectly implemented, allowing software to reprogram them multiple times.
CWE-1229Creation of Emergent ResourceThis vulnerability occurs when a system's normal operations unintentionally create new, exploitable resources that attackers can use to bypass security controls.
CWE-123Write-what-where ConditionA write-what-where condition occurs when an attacker can control both the data written and the exact memory location where it's written, often due to a severe memory corruption flaw like a buffer overflow.
CWE-1230Exposure of Sensitive Information Through MetadataThis vulnerability occurs when an application protects the primary source of sensitive data but fails to secure the metadata derived from it. Attackers can then access this secondary information, which may leak critical details about the original content.
CWE-1231Improper Prevention of Lock Bit ModificationThis vulnerability occurs when hardware or firmware uses a lock bit to protect critical system registers or memory regions, but fails to properly prevent that lock bit from being changed after it has been enabled. This design flaw allows attackers to bypass hardware-enforced security restrictions.
CWE-1232Improper Lock Behavior After Power State TransitionThis vulnerability occurs when a hardware lock bit, designed to protect critical system configuration registers, is improperly reset or becomes programmable after a device transitions between power states, such as entering or waking from a low-power sleep mode. This allows the protected configuration to be altered after it should be permanently locked.
CWE-1233Security-Sensitive Hardware Controls with Missing Lock Bit ProtectionThis vulnerability occurs when a hardware device uses a lock bit to protect critical configuration registers, but the lock fails to prevent writes to all registers that can alter the protected system settings. Essentially, the security mechanism is incomplete, allowing software to bypass it and modify sensitive hardware configurations.
CWE-1234Hardware Internal or Debug Modes Allow Override of LocksHardware debug modes or internal states can bypass critical system lock protections, allowing unauthorized changes to device configuration.
CWE-1235Incorrect Use of Autoboxing and Unboxing for Performance Critical OperationsThis weakness occurs when a program relies on automatic boxing and unboxing of primitive types within performance-sensitive code sections, causing unnecessary computational overhead and potential resource strain.
CWE-1236Improper Neutralization of Formula Elements in a CSV FileThis vulnerability occurs when an application writes user-supplied data into a CSV file without properly sanitizing special characters. Spreadsheet programs like Excel or Google Sheets interpret entries starting with '=' as executable formulas, which can lead to malicious command execution when the file is opened.
CWE-1239Improper Zeroization of Hardware RegisterThis vulnerability occurs when a hardware component fails to properly erase sensitive data from its internal registers before a new user or process gains access to the hardware block.
CWE-124Buffer Underwrite ('Buffer Underflow')A buffer underwrite, also known as buffer underflow, happens when a program writes data to a memory location before the official start of a buffer.
CWE-1240Use of a Cryptographic Primitive with a Risky ImplementationThis weakness occurs when a product uses a custom, unverified, or non-compliant implementation of a cryptographic algorithm instead of a trusted, standard solution.

CWE-175Improper Handling of Mixed EncodingThis vulnerability occurs when software fails to correctly process input that contains multiple character encodings within the same data stream.
CWE-176Improper Handling of Unicode EncodingThis vulnerability occurs when software fails to correctly process or interpret Unicode-encoded input, leading to security bypasses, data corruption, or unexpected behavior.
CWE-177Improper Handling of URL Encoding (Hex Encoding)This vulnerability occurs when an application fails to correctly process URL-encoded (also known as percent-encoded or hex-encoded) input, either by double-decoding it, not decoding it at all, or inconsistently handling encoded characters across different security checks.
CWE-178Improper Handling of Case SensitivityThis vulnerability occurs when software fails to consistently handle uppercase and lowercase letters when checking or accessing resources, leading to unpredictable behavior and security gaps.
CWE-179Incorrect Behavior Order: Early ValidationThis vulnerability occurs when an application validates user input before applying security filters or data normalization. Attackers can exploit this order of operations by submitting specially crafted input that passes the initial validation but becomes malicious after the application's filters or canonicalization processes modify it.
CWE-180Incorrect Behavior Order: Validate Before CanonicalizeThis vulnerability occurs when a system checks user input for malicious content before standardizing its format, allowing specially crafted data to bypass security checks.
CWE-181Incorrect Behavior Order: Validate Before FilterThis vulnerability occurs when a system checks user input for validity before cleaning or filtering it. This flawed sequence allows malicious data to pass validation, only to be altered by later filters into a dangerous form.
CWE-182Collapse of Data into Unsafe ValueThis vulnerability occurs when an application's data filtering or transformation process incorrectly merges or simplifies information, producing a result that violates security rules. Essentially, safe input gets collapsed into a dangerous value.
CWE-183Permissive List of Allowed InputsThis vulnerability occurs when an application's security filter uses an allowlist that is too broad, mistakenly permitting dangerous inputs that should have been blocked. The flawed assumption that everything on the list is safe creates a direct path for attackers to exploit the system.
CWE-184Incomplete List of Disallowed InputsThis vulnerability occurs when a security filter or validation mechanism relies on a 'denylist'—a predefined list of forbidden inputs—but that list is missing critical entries. Attackers can bypass the protection by using variations or inputs the developers didn't anticipate.
CWE-185Incorrect Regular ExpressionThis vulnerability occurs when a regular expression is written incorrectly, causing it to match or validate data in unintended and potentially dangerous ways.
CWE-186Overly Restrictive Regular ExpressionThis weakness occurs when a regular expression is too narrow, failing to detect all the dangerous or unexpected input values it was designed to catch.

CWE-188Reliance on Data/Memory LayoutThis vulnerability occurs when software incorrectly assumes how data is structured in memory or within network packets, leading to unexpected behavior when those underlying layouts change.
CWE-190Integer Overflow or WraparoundInteger overflow or wraparound occurs when a calculation produces a numeric result that exceeds the maximum value a variable can hold. Instead of increasing as expected, the value wraps around to a very small or negative number, breaking the program's logic.
CWE-191Integer Underflow (Wrap or Wraparound)Integer underflow occurs when a subtraction operation results in a value smaller than the data type's minimum limit, causing the value to wrap around to a large, incorrect number.
CWE-192Integer Coercion ErrorAn integer coercion error occurs when a program incorrectly converts, extends, or truncates a number between different data types, leading to unexpected values.
CWE-193Off-by-one ErrorAn off-by-one error occurs when a program incorrectly calculates a boundary, such as a loop counter or array index, by being one unit too high or too low. This often leads to buffer overflows, memory corruption, or unexpected program behavior.
CWE-194Unexpected Sign ExtensionThis vulnerability occurs when a signed number from a smaller data type is moved or cast to a larger type, causing its sign bit to be incorrectly extended. If the original value is negative, this sign extension can fill the new, higher-order bits with '1's, leading to unexpectedly large positive values and causing logic errors, buffer overflows, or security bypasses.
CWE-195Signed to Unsigned Conversion ErrorThis vulnerability occurs when a signed integer (which can hold negative values) is converted to an unsigned integer (which holds only non-negative values). If the original signed value is negative, the conversion produces a large, unexpected positive number instead of an error, breaking the program's logic.
CWE-196Unsigned to Signed Conversion ErrorThis vulnerability occurs when a program takes an unsigned integer and converts it directly to a signed integer. If the original unsigned value is too large to fit within the signed type's positive range, the conversion results in an unexpected negative number, corrupting the data.
CWE-197Numeric Truncation ErrorA numeric truncation error happens when a program converts a number to a smaller data type, cutting off its higher-order bits and corrupting the original value.
CWE-198Use of Incorrect Byte OrderingThis vulnerability occurs when software processes data from another system without considering byte order (endianness), such as big-endian or little-endian. This mismatch can cause the program to misinterpret numbers or values, leading to incorrect calculations, crashes, or security flaws.
CWE-20Improper Input ValidationThis vulnerability occurs when an application accepts data from an external source but fails to properly verify that the data is safe and correctly formatted before using it. This missing or flawed validation check allows malicious or malformed inputs to disrupt the application's logic or security.

CWE-26Path Traversal: '/dir/../filename'This vulnerability occurs when an application builds a file path using user input but fails to properly block directory traversal sequences like '/dir/../filename'. This allows an attacker to break out of the intended restricted directory and access files or folders elsewhere on the system.
CWE-260Password in Configuration FileThis vulnerability occurs when an application stores sensitive passwords directly within a configuration file, making them easily readable to anyone with access to that file.
CWE-261Weak Encoding for PasswordUsing simple encoding like Base64 to hide a password provides no real security, as it can be easily reversed.
CWE-262Not Using Password AgingThis vulnerability occurs when a system lacks password expiration policies, allowing users to keep the same password indefinitely.
CWE-263Password Aging with Long ExpirationThe system enforces password changes, but the time allowed between changes is excessively long, weakening security.
CWE-266Incorrect Privilege AssignmentThis vulnerability occurs when a system mistakenly grants a user, process, or entity a specific permission or privilege they should not have. This error creates an unintended level of access, allowing the actor to perform actions beyond their intended authority.
CWE-267Privilege Defined With Unsafe ActionsThis vulnerability occurs when a system grants a user, role, or process a specific permission that can be misused to perform dangerous, unintended actions. The permission itself is correctly assigned, but its scope is too broad or allows for unsafe operations.
CWE-268Privilege ChainingPrivilege chaining occurs when an attacker combines two separate permissions or capabilities, neither of which is dangerous on its own, to perform a harmful action that neither permission should individually allow.
CWE-269Improper Privilege ManagementThis vulnerability occurs when an application fails to correctly manage user permissions, allowing someone to perform actions or access data beyond their intended authority.
CWE-27Path Traversal: 'dir/../../filename'This vulnerability occurs when an application builds file paths using user input but fails to properly block sequences like 'dir/../../filename'.

CWE-276Incorrect Default PermissionsThis vulnerability occurs when software installation scripts set overly permissive file or directory access rights by default. Instead of restricting write access to authorized users or processes, the installation allows unintended actors to modify, delete, or corrupt critical application files.
CWE-277Insecure Inherited PermissionsThis vulnerability occurs when an application sets default file or directory permissions that are too permissive, and these insecure settings are automatically passed down to new files or objects the program creates.
CWE-278Insecure Preserved Inherited PermissionsThis vulnerability occurs when a software product copies or extracts files while unintentionally preserving insecure permissions from their original source, such as an archive, without the user's knowledge or consent.
CWE-279Incorrect Execution-Assigned PermissionsThis vulnerability occurs when a running application incorrectly changes an object's access permissions, overriding the security settings that a user or administrator intentionally configured.
CWE-28Path Traversal: '..\filedir'This vulnerability occurs when an application builds a file path using user input but fails to block or properly handle '..\' sequences. This oversight allows an attacker to break out of the intended directory and navigate to unauthorized locations in the file system.
CWE-280Improper Handling of Insufficient Permissions or Privileges This vulnerability occurs when a system fails to properly manage situations where it lacks the necessary permissions to perform an action or access a resource. This flawed handling can force the application into unintended states or error paths, potentially leading to crashes, data corruption, or security bypasses.
CWE-281Improper Preservation of PermissionsThis vulnerability occurs when a system fails to correctly maintain file or object permissions during operations like copying, sharing, or restoring data.

CWE-293Using Referer Field for AuthenticationThis vulnerability occurs when a web application uses the HTTP Referer header as a sole or primary method for authentication or authorization decisions. Since this header is entirely controlled by the user's browser or client and can be easily forged, it provides no reliable security.
CWE-294Authentication Bypass by Capture-replayThis vulnerability occurs when an attacker can intercept and record legitimate authentication traffic, then replay it later to gain unauthorized access. The system accepts the replayed data as valid, effectively bypassing normal authentication checks.
CWE-295Improper Certificate ValidationThis vulnerability occurs when an application fails to properly verify the authenticity of a digital certificate, or performs the verification incorrectly, allowing untrusted connections to appear legitimate.
CWE-296Improper Following of a Certificate's Chain of TrustThis vulnerability occurs when software fails to properly validate the entire certificate chain back to a trusted root authority. This mistake can cause the system to incorrectly trust a certificate and the resource it represents, creating a security gap.
CWE-297Improper Validation of Certificate with Host MismatchThis vulnerability occurs when an application accepts a valid SSL/TLS certificate without properly verifying that it actually belongs to the specific host it's connecting to. Even a correctly signed certificate from a trusted authority can be misused if the hostname check is missing or flawed.
CWE-298Improper Validation of Certificate ExpirationThis vulnerability occurs when an application fails to properly check if a digital certificate has expired, potentially trusting certificates that are no longer valid due to their age.
CWE-299Improper Check for Certificate RevocationThis vulnerability occurs when an application fails to properly verify whether a security certificate has been revoked, potentially allowing it to accept and use a compromised or untrustworthy certificate.
CWE-30Path Traversal: '\dir\..\filename'This vulnerability occurs when an application builds file paths using user input but fails to properly sanitize sequences like '\dir\..\filename'. Attackers can exploit this to escape the intended directory and access unauthorized files or folders elsewhere on the system.
CWE-300Channel Accessible by Non-EndpointThis vulnerability occurs when a system fails to properly verify who is on the other end of a communication link or to secure the channel itself. This allows an unauthorized third party to access or manipulate the communication as if they were a legitimate participant.
CWE-301Reflection Attack in an Authentication ProtocolA reflection attack is a flaw in mutual authentication protocols that allows an attacker to impersonate a legitimate user without knowing the secret key. This happens when an attacker can bounce, or 'reflect,' a server's own challenge back to it using a second connection, tricking the system into granting access.

CWE-347Improper Verification of Cryptographic SignatureThis vulnerability occurs when an application fails to properly check the digital signature on data, or skips the verification step entirely, allowing tampered or forged information to be accepted as legitimate.
CWE-348Use of Less Trusted SourceThis vulnerability occurs when a system has access to multiple sources for the same critical data, but it chooses to rely on the less secure or less trustworthy one. This creates a security gap because the system ignores better-protected alternatives that offer stronger verification or are harder for attackers to compromise.
CWE-349Acceptance of Extraneous Untrusted Data With Trusted DataThis vulnerability occurs when a system processes both trusted and untrusted data together, but fails to separate them. The application incorrectly treats all incoming data—including the untrusted portion—with the same level of trust as the legitimate data.
CWE-35Path Traversal: '.../...//'This vulnerability occurs when an application builds file paths using user input but fails to properly sanitize the '.../...//' sequence. Attackers can use this specific pattern to break out of the intended directory and access unauthorized files or folders elsewhere on the system.
CWE-350Reliance on Reverse DNS Resolution for a Security-Critical ActionThis vulnerability occurs when an application uses a reverse DNS lookup on an IP address to get a hostname and then uses that hostname for a security decision—like access control or logging—without verifying that the IP address actually belongs to that hostname.
CWE-351Insufficient Type DistinctionThis vulnerability occurs when an application fails to properly differentiate between different types of data or objects, leading to unintended and insecure behavior.
CWE-352Cross-Site Request Forgery (CSRF)Cross-Site Request Forgery (CSRF) happens when a web application cannot reliably tell if a user actually intended to submit a request, allowing an attacker to trick a user's browser into performing unwanted actions on their behalf.

CWE-363Race Condition Enabling Link FollowingThis vulnerability occurs when a program checks a file's status before using it, creating a brief window where an attacker can replace that file with a malicious link. This causes the program to follow the link and access an unintended, potentially dangerous location.
CWE-364Signal Handler Race ConditionA signal handler race condition occurs when a program's signal handling routine is vulnerable to timing issues, allowing its state to be corrupted through asynchronous execution.
CWE-365DEPRECATED: Race Condition in SwitchThis deprecated entry originally suggested a race condition could occur if a switch statement's controlling expression was evaluated multiple times. In practice, this doesn't happen—the expression is evaluated just once, making this specific scenario not a valid software weakness.
CWE-366Race Condition within a ThreadThis vulnerability occurs when two or more threads within the same application access and manipulate a shared resource (like a variable, data structure, or file) without proper synchronization. Because the threads can execute in an unpredictable order, they can corrupt the resource's state, leading to crashes, incorrect calculations, or data loss.
CWE-367Time-of-check Time-of-use (TOCTOU) Race ConditionThis vulnerability occurs when a program verifies a resource's state (like a file's permissions or existence) but then uses it after that state has already changed. The gap between checking and using creates a race window where an attacker can manipulate the resource, causing the program to operate on invalid or malicious data.
CWE-368Context Switching Race ConditionThis vulnerability occurs when an application switches between different security contexts (like privilege levels or domains) using a series of steps that can be interrupted. An attacker can exploit the timing gap during this switch to trick the application into performing actions with the wrong permissions or resources.
CWE-369Divide By ZeroA divide-by-zero error occurs when software attempts to perform a division operation where the denominator is zero.
CWE-37Path Traversal: '/absolute/pathname/here'This vulnerability occurs when an application accepts user input containing absolute file paths (starting with a forward slash like '/etc/passwd') and uses it to access files without proper security checks. Attackers can exploit this to read, write, or delete sensitive files anywhere on the server's filesystem.
CWE-370Missing Check for Certificate Revocation after Initial CheckThis vulnerability occurs when software only verifies a certificate's revocation status once, then continues to trust it for subsequent privileged actions without re-checking. This allows operations to proceed even if the certificate is revoked later.
CWE-372Incomplete Internal State DistinctionThis vulnerability occurs when an application fails to accurately track its own operational state. The system incorrectly assumes it's in one mode or condition when it's actually in another, leading to security-critical actions being performed with the wrong assumptions.
CWE-373DEPRECATED: State Synchronization ErrorThis entry has been retired because its core concept—errors that occur when different parts of a system fail to coordinate their shared state correctly—is fully covered by two more precise and actively maintained categories: Race Conditions (CWE-362) and Improper Synchronization (CWE-662).
CWE-374Passing Mutable Objects to an Untrusted MethodThis vulnerability occurs when a function receives a direct reference to mutable data, such as an object or array, instead of a safe copy of that data.
CWE-375Returning a Mutable Object to an Untrusted CallerThis vulnerability occurs when a method directly returns a reference to its internal mutable data, allowing untrusted calling code to modify that data unexpectedly.
CWE-377Insecure Temporary FileThis vulnerability occurs when an application creates temporary files with insecure permissions or in predictable locations, allowing attackers to read, modify, or delete sensitive data.
CWE-378Creation of Temporary File With Insecure PermissionsThis vulnerability occurs when a program creates a temporary file but sets its file permissions too loosely, allowing other users or processes on the system to read, modify, or delete the file.

CWE-38Path Traversal: '\absolute\pathname\here'This vulnerability occurs when an application accepts user-supplied input containing Windows-style absolute paths (like '\absolute\pathname\here') without proper validation. Attackers can exploit this to navigate outside the intended directory and access or manipulate sensitive files anywhere on the server's file system.
CWE-382J2EE Bad Practices: Use of System.exit()This vulnerability occurs when a J2EE application directly calls System.exit(), which forcibly terminates the entire application server process, not just the application itself.
CWE-383J2EE Bad Practices: Direct Use of ThreadsCreating or managing threads directly within a J2EE application is a risky practice that violates the platform's standards and often leads to unstable applications.
CWE-384Session FixationSession fixation occurs when an application authenticates a user without first destroying the previous session ID. This allows an attacker who knows that session identifier to hijack the user's authenticated session.
CWE-385Covert Timing ChannelA covert timing channel is a security flaw where an attacker can deduce secret information by observing how long certain operations take to execute. Instead of directly reading data, they analyze timing variations in system behavior to infer protected details.
CWE-386Symbolic Name not Mapping to Correct ObjectThis vulnerability occurs when a program uses a fixed symbolic name (like a constant or identifier) to refer to an object, but that name can later point to a different, unintended object during execution.
CWE-39Path Traversal: 'C:dirname'This vulnerability occurs when an application accepts user input containing Windows drive letters (like 'C:dirname') without proper validation, allowing attackers to redirect file operations to unintended locations or access arbitrary files on the system.
CWE-390Detection of Error Condition Without ActionThis weakness occurs when software successfully identifies an error condition but then fails to take any meaningful action to address it. The error is detected but ignored, leaving the system in an inconsistent or vulnerable state.
CWE-391Unchecked Error ConditionThis vulnerability occurs when a program fails to properly check or handle error conditions, such as exceptions or return codes. By ignoring these failures, the software can enter an unexpected state that attackers might exploit, often without any logging or user notification.
CWE-392Missing Report of Error ConditionThis vulnerability occurs when a system fails to properly signal that an error has happened. Instead of returning a clear error code, status, or exception, the software continues as if nothing went wrong, leaving other components unaware of the failure.
CWE-393Return of Wrong Status CodeThis vulnerability occurs when a function returns an inaccurate status code or value that misrepresents the actual outcome of an operation. This false signal can cause the application to behave in unexpected and potentially insecure ways.
CWE-394Unexpected Status Code or Return ValueThis vulnerability occurs when software fails to properly validate the full range of possible return values from a function or system call. While a returned value might be technically valid for that operation, the application doesn't anticipate or handle it correctly, leading to unexpected behavior.
CWE-395Use of NullPointerException Catch to Detect NULL Pointer DereferenceUsing a try-catch block for NullPointerException as a substitute for proper null checks is an anti-pattern. This approach masks the root cause of null pointer dereferences instead of preventing them, leading to unstable and difficult-to-debug code.
CWE-396Declaration of Catch for Generic ExceptionThis weakness occurs when code catches a generic exception type like 'Exception' or 'Throwable', which can hide specific errors and create insecure error handling logic.
CWE-397Declaration of Throws for Generic ExceptionThis vulnerability occurs when a method is declared to throw an overly broad exception type, such as a generic 'Exception' or 'Throwable'. This practice masks the specific error conditions that can occur, making it difficult for calling code to handle failures appropriately.
CWE-40Path Traversal: '\\UNC\share\name\' (Windows UNC Share)This vulnerability occurs when an application accepts user input containing a Windows UNC share path (like '\\UNC\share\name') without proper validation, allowing attackers to redirect file operations to unintended network locations or arbitrary files.

CWE-402Transmission of Private Resources into a New Sphere ('Resource Leak')This vulnerability occurs when an application unintentionally exposes internal resources, like files, memory, or database connections, to unauthorized users or systems. Essentially, it's a type of resource leak where sensitive assets cross a security boundary.
CWE-403Exposure of File Descriptor to Unintended Control Sphere ('File Descriptor Leak')This vulnerability occurs when a parent process launches a child process without first closing sensitive file descriptors. The child process inherits these open handles, potentially gaining unauthorized access to files, sockets, or other resources it shouldn't be able to interact with.
CWE-404Improper Resource Shutdown or ReleaseThis vulnerability occurs when a program fails to properly close or release a system resource—like a file handle, database connection, or memory block—after it's no longer needed, preventing its reuse.
CWE-405Asymmetric Resource Consumption (Amplification)This vulnerability occurs when a system allows an attacker to trigger a disproportionate amount of resource consumption—like CPU, memory, or bandwidth—with minimal effort on their part. The attacker's small input causes a large, inefficient output, creating an unfair 'asymmetric' advantage.
CWE-406Insufficient Control of Network Message Volume (Network Amplification)This vulnerability occurs when a system fails to properly limit the amount of network traffic it can generate in response to a request, allowing an attacker to abuse it to send a disproportionately large volume of data.
CWE-407Inefficient Algorithmic ComplexityThis vulnerability occurs when a software component uses an algorithm with poor worst-case performance. An attacker can exploit this by providing specially crafted input that forces the algorithm into its slowest possible execution path, leading to severe performance degradation or denial of service.
CWE-408Incorrect Behavior Order: Early AmplificationThis vulnerability occurs when a system allows a user to trigger a resource-intensive operation before verifying their identity or checking their permissions.
CWE-409Improper Handling of Highly Compressed Data (Data Amplification)This vulnerability occurs when software fails to safely process highly compressed data, where a small input file can trigger the creation of an extremely large amount of data during decompression, overwhelming system resources.
CWE-41Improper Resolution of Path EquivalenceThis vulnerability occurs when an application fails to properly handle different text representations that refer to the same file or directory on the system. Attackers can use special characters or alternative naming conventions to bypass security checks and access restricted files.

CWE-412Unrestricted Externally Accessible LockThis vulnerability occurs when a system correctly checks for a lock's existence, but an unauthorized external actor can control or influence that lock.
CWE-413Improper Resource LockingThis vulnerability occurs when an application fails to properly lock a shared resource, such as a file or memory location, before performing operations that require exclusive access.
CWE-414Missing Lock CheckThis vulnerability occurs when software fails to verify that a proper synchronization lock is active before accessing or modifying a shared resource, potentially leading to race conditions and data corruption.
CWE-415Double FreeA double free vulnerability occurs when a program mistakenly calls the 'free()' function twice on the same block of memory.
CWE-416Use After FreeUse After Free happens when a program continues to use a pointer to a memory location after that memory has been freed. This can lead to unpredictable behavior, crashes, or security vulnerabilities because the freed memory may have been reallocated for a different purpose.
CWE-419Unprotected Primary ChannelThis vulnerability occurs when an application exposes a privileged administrative interface or restricted functionality through a primary channel (like a specific port, endpoint, or protocol) without implementing adequate security controls to protect it.
CWE-42Path Equivalence: 'filename.' (Trailing Dot)This vulnerability occurs when a system accepts file or directory paths that end with a dot (like 'file.txt.' or 'folder.') without properly checking them. Attackers can exploit this to bypass security checks, potentially accessing files or directories they shouldn't be able to reach.
CWE-420Unprotected Alternate ChannelThis vulnerability occurs when an application secures its main communication path but leaves a backup or alternative channel with weaker or no protection.
CWE-421Race Condition During Access to Alternate ChannelA race condition occurs when an application opens a secondary communication channel intended for an authorized user, but fails to secure it, allowing other actors to potentially access it first.
CWE-422Unprotected Windows Messaging Channel ('Shatter')This vulnerability, often called a 'Shatter' attack, occurs when a Windows application running with high privileges accepts messages from the Windows messaging system without verifying their source. This allows a less-privileged or malicious application to send commands directly to the privileged application, potentially hijacking its functionality.
CWE-423DEPRECATED: Proxied Trusted ChannelThis entry is no longer active. It was merged into CWE-441 (The 'Proxied Trusted Channel' weakness) to eliminate duplication. Please refer to CWE-441 for all related information.
CWE-424Improper Protection of Alternate PathThis vulnerability occurs when an application fails to secure every possible route a user could take to reach sensitive features or data, leaving backdoors or unintended access points open.
CWE-425Direct Request ('Forced Browsing')This vulnerability occurs when a web application fails to verify user permissions for every protected page, file, or API endpoint, allowing attackers to access them directly.
CWE-426Untrusted Search PathThis vulnerability occurs when an application relies on an external search path, provided by a user or environment, to find and load critical resources like executables or libraries. Because the application does not fully control this path, an attacker can manipulate it to point to malicious files.
CWE-427Uncontrolled Search Path ElementThis vulnerability occurs when an application searches for critical files like libraries or executables using a predefined list of directories, but one or more of those directories can be manipulated by an unauthorized user.
CWE-428Unquoted Search Path or ElementThis vulnerability occurs when a program uses a file path or command that contains spaces and is not enclosed in quotes. The operating system may misinterpret where the executable file is located, potentially allowing an attacker to run a malicious program with higher privileges.
CWE-43Path Equivalence: 'filename....' (Multiple Trailing Dot)This vulnerability occurs when an application accepts file or directory paths containing multiple trailing dots (like 'file....') without proper validation. Attackers can exploit this to bypass security checks, potentially accessing files or directories outside the intended scope.

CWE-431Missing HandlerThis vulnerability occurs when a software component lacks the necessary code to properly handle an error or unexpected event.
CWE-432Dangerous Signal Handler not Disabled During Sensitive OperationsThis vulnerability occurs when a program's signal handler, which shares resources like global variables with other handlers, can be interrupted and re-entered before it finishes its work. The program fails to block other signals during this sensitive operation, leaving shared state vulnerable to corruption.
CWE-433Unparsed Raw Web Content DeliveryThis vulnerability occurs when a web application stores unprocessed files—like configuration scripts or raw source code—in publicly accessible directories using file extensions the server doesn't recognize.
CWE-434Unrestricted Upload of File with Dangerous TypeThis vulnerability occurs when an application accepts file uploads without properly restricting the file types, allowing attackers to upload and execute malicious files on the server.
CWE-435Improper Interaction Between Multiple Correctly-Behaving EntitiesThis weakness occurs when individually secure components interact in unexpected ways within a larger system, creating new security flaws that weren't present in isolation.
CWE-436Interpretation ConflictAn interpretation conflict occurs when two systems process the same data or sequence of events differently, leading one system to make incorrect decisions based on its flawed understanding of the other's state.
CWE-437Incomplete Model of Endpoint FeaturesThis vulnerability occurs when a security product, proxy, or monitoring system sits between endpoints but lacks a full understanding of what those endpoints can do or their current state. Because it's working with incomplete information, it can make wrong decisions, allowing malicious traffic to pass or incorrectly blocking legitimate requests.
CWE-439Behavioral Change in New Version or EnvironmentThis vulnerability occurs when a component's behavior unexpectedly changes after an update or when deployed to a different environment, and the systems or users depending on it are unaware of and cannot manage this change.
CWE-44Path Equivalence: 'file.name' (Internal Dot)This vulnerability occurs when an application accepts file paths containing internal dots (like 'file.ordir') without properly checking them. Attackers can exploit this to bypass security checks, traverse directories, and access sensitive files or system areas they shouldn't be able to reach.
CWE-440Expected Behavior ViolationThis weakness occurs when a software component, such as a function, API, or feature, fails to act as documented or intended. The system's actual behavior deviates from its promised specification, leading to unpredictable results.
CWE-441Unintended Proxy or Intermediary ('Confused Deputy')A confused deputy vulnerability occurs when a system receives a request from a client and forwards it to an external destination without properly identifying the original source. This makes the system appear to be the originator of the request, effectively turning it into an unintended proxy for the client.
CWE-443DEPRECATED: HTTP response splittingThis entry has been deprecated and consolidated into CWE-113: Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Response Splitting').
CWE-444Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling')This weakness occurs when a proxy, firewall, or other intermediary HTTP agent interprets a malformed HTTP request or response differently than the final destination server or client. This inconsistency allows an attacker to craft messages that bypass the intermediary's security checks.
CWE-446UI Discrepancy for Security FeatureThis vulnerability occurs when a user interface incorrectly displays a security feature as active or properly configured, misleading users into believing they are protected when they are not.
CWE-447Unimplemented or Unsupported Feature in UIThis vulnerability occurs when a user interface displays a security feature as active and functional, but the underlying code that powers it is either missing or disabled. Users receive visual confirmation that a protection is in place, creating a false sense of security.
CWE-448Obsolete Feature in UIThis vulnerability occurs when a user interface (UI) includes outdated or deprecated features, but fails to alert users about their obsolete status. This can mislead users into relying on functionality that may be broken, unsupported, or pose a security risk.
CWE-449The UI Performs the Wrong ActionThis vulnerability occurs when a user interface (UI) element or command performs a different, unintended action than what the user requested, potentially leading to security bypass, data corruption, or unexpected system behavior.
CWE-45Path Equivalence: 'file...name' (Multiple Internal Dot)This vulnerability occurs when an application accepts file paths containing sequences of multiple internal dots (like 'file...name') without proper validation. Attackers can exploit this ambiguity to bypass security checks, traverse directories, and access sensitive files or system areas they shouldn't be able to reach.
CWE-450Multiple Interpretations of UI InputThis vulnerability occurs when a user interface can interpret the same input in multiple ways, but automatically chooses a less secure option without warning the user.
CWE-451User Interface (UI) Misrepresentation of Critical InformationThis vulnerability occurs when a user interface fails to accurately display or highlight crucial information, potentially misleading users about the true state of the system or the source of data. Attackers exploit this weakness to trick users into performing unintended actions, often as part of phishing campaigns or other deception-based attacks.
CWE-453Insecure Default Variable InitializationThis vulnerability occurs when software sets an internal variable to an insecure or unnecessarily weak default value during initialization, rather than using the most secure option available.
CWE-454External Initialization of Trusted Variables or Data StoresThis vulnerability occurs when an application sets up its critical internal variables or storage systems using data from untrusted, external sources that an attacker could control.
CWE-455Non-exit on Failed InitializationThis vulnerability occurs when software continues to run as normal after encountering a critical security failure during its startup process. Instead of halting or entering a safe mode, the application proceeds with weakened or missing security controls, leaving it exposed.
CWE-456Missing Initialization of a VariableThis vulnerability occurs when a program uses a variable before giving it a starting value, causing the software to rely on unpredictable data left over in memory.
CWE-457Use of Uninitialized VariableThis vulnerability occurs when a program accesses a variable before it has been assigned a value, leading to unpredictable behavior and potential security risks.
CWE-458DEPRECATED: Incorrect InitializationThis CWE entry has been retired. Its original description overlapped with another vulnerability (CWE-454), while its name pointed to a broader category of initialization issues. For guidance on improper initialization problems, please see CWE-665.
CWE-459Incomplete CleanupThis vulnerability occurs when an application fails to properly remove temporary files, data structures, or system resources after they are no longer needed.
CWE-46Path Equivalence: 'filename ' (Trailing Space)This vulnerability occurs when an application processes file paths that end with a space character (like 'document.txt ') without properly normalizing or rejecting them. Because many operating systems ignore trailing spaces in paths, this can cause the application to resolve the path differently than intended, potentially allowing attackers to access unauthorized files or directories.

CWE-480Use of Incorrect OperatorThis vulnerability occurs when a developer mistakenly uses the wrong operator in their code, leading to unintended and potentially insecure logic.
CWE-481Assigning instead of ComparingThis flaw occurs when a developer accidentally uses the assignment operator (=) instead of the comparison operator (== or ===). The code assigns a value when it was meant to check for equality, which fundamentally changes the program's logic.
CWE-482Comparing instead of AssigningThis vulnerability occurs when a developer accidentally uses a comparison operator (like '==') where an assignment operator (like '=') was intended, creating a logic error instead of setting a value.
CWE-483Incorrect Block DelimitationThis vulnerability occurs when a developer fails to use explicit braces or delimiters to group multiple statements within a block, leading to unexpected program logic.
CWE-484Omitted Break Statement in SwitchThis vulnerability occurs when a developer forgets to include a 'break' statement inside a switch-case block. Without it, the code execution 'falls through' and unintentionally runs the logic for subsequent cases, leading to unexpected behavior.
CWE-486Comparison of Classes by NameThis vulnerability occurs when an application determines an object's trustworthiness or behavior solely by checking its class name. Since multiple classes can share identical names across different packages or classloaders, this comparison can lead to using the wrong, potentially malicious, class.
CWE-487Reliance on Package-level ScopeThis weakness occurs when a Java application mistakenly treats package-level access as a security boundary, assuming it can prevent unauthorized access to code.
CWE-488Exposure of Data Element to Wrong SessionThis vulnerability occurs when an application fails to properly isolate data between different user sessions, allowing information from one user's session to leak into another's.
CWE-489Active Debug CodeThis vulnerability occurs when software is deployed to production with debugging or diagnostic features still enabled and accessible.
CWE-49Path Equivalence: 'filename/' (Trailing Slash)This vulnerability occurs when an application accepts file or directory paths that end with a slash (e.g., 'documents/') without properly normalizing them. This can confuse the system's path resolution logic, potentially allowing an attacker to bypass security checks and access files or directories they shouldn't.
CWE-491Public cloneable() Method Without Final ('Object Hijack')This vulnerability occurs when a class implements a public clone() method without declaring it final. This allows attackers to create copies of objects without invoking their constructors, potentially leaving the cloned object in an inconsistent or insecure state.
CWE-492Use of Inner Class Containing Sensitive DataUsing inner classes to handle sensitive data can unintentionally expose that data because of how Java compiles them. The compiler transforms inner classes into separate, package-visible classes, which can bypass the intended private access restrictions.
CWE-493Critical Public Variable Without Final ModifierThis vulnerability occurs when a security-sensitive variable is declared as public but not marked as final, allowing untrusted code to unexpectedly change its value after initialization.
CWE-494Download of Code Without Integrity CheckThis vulnerability occurs when an application fetches and runs code from an external source—like a remote server or CDN—without properly verifying where it came from or ensuring it hasn't been tampered with.
CWE-495Private Data Structure Returned From A Public MethodThis vulnerability occurs when a public method directly returns a reference to a private, internal data structure. Because the reference is live, external callers can bypass intended controls and modify the data unexpectedly, corrupting the application's state.
CWE-496Public Data Assigned to Private Array-Typed FieldThis vulnerability occurs when a developer stores sensitive data in a private array, but then assigns a publicly accessible reference to that same array. This effectively makes all the private array's contents available to unauthorized code, bypassing intended access controls.

CWE-580clone() Method Without super.clone()This vulnerability occurs when a class's clone() method creates a new object directly instead of calling super.clone().
CWE-581Object Model Violation: Just One of Equals and Hashcode DefinedThis vulnerability occurs when a Java class defines either the equals() method or the hashCode() method, but not both, breaking a fundamental contract of object equality.
CWE-582Array Declared Public, Final, and StaticThis vulnerability occurs when an array is declared as public, final, and static, which does not protect the data inside the array from being altered.
CWE-583finalize() Method Declared PublicThis vulnerability occurs when a Java class declares its finalize() method as public, violating secure coding practices for mobile code.
CWE-584Return Inside Finally BlockThis vulnerability occurs when a function places a return statement inside a finally block. This dangerous pattern silently discards any unhandled exceptions thrown earlier in the try block, making errors invisible and undermining application stability.
CWE-585Empty Synchronized BlockAn empty synchronized block is a Java code construct where a synchronized block exists but contains no executable statements inside it.
CWE-586Explicit Call to Finalize()This vulnerability occurs when code directly calls an object's finalize() method from outside its designated finalizer context.
CWE-587Assignment of a Fixed Address to a PointerThis vulnerability occurs when code explicitly assigns a hardcoded memory address to a pointer, instead of using a dynamic or null value.
CWE-588Attempt to Access Child of a Non-structure PointerThis vulnerability occurs when code incorrectly treats a pointer to a basic data type (like an integer) as if it points to a structured object (like a 'struct' in C). The program then tries to access a member field that doesn't exist at that memory location, which can cause crashes or corrupt adjacent data.
CWE-589Call to Non-ubiquitous APIThis vulnerability occurs when software relies on an operating system function that isn't available on all versions of the target platform. This can cause crashes, unexpected behavior, or security failures when the software runs in an environment where the API is missing.
CWE-59Improper Link Resolution Before File Access ('Link Following')This vulnerability occurs when an application uses a filename to access a file but fails to properly check if that name points to a symbolic link, shortcut, or junction. This allows an attacker to manipulate the link's target, causing the application to read or write to an unintended, potentially sensitive location.
CWE-590Free of Memory not on the HeapThis vulnerability occurs when a program calls free() on a memory pointer that wasn't originally allocated using standard heap functions like malloc(), calloc(), or realloc().
CWE-591Sensitive Data Storage in Improperly Locked MemoryThis vulnerability occurs when an application stores sensitive information, like passwords or encryption keys, in system memory that isn't properly secured from being written to disk. If the memory isn't locked, the operating system's virtual memory manager can swap it to a page or swap file, leaving the data exposed on the storage drive where attackers could potentially recover it.
CWE-592DEPRECATED: Authentication Bypass IssuesThis entry has been retired because its core concept—authentication bypass vulnerabilities—is fully covered by CWE-287: Improper Authentication. It was removed to eliminate redundancy and streamline the CWE list.
CWE-593Authentication Bypass: OpenSSL CTX Object Modified after SSL Objects are CreatedThis vulnerability occurs when an application modifies an OpenSSL context object after it has already been used to create active SSL/TLS connections.
CWE-594J2EE Framework: Saving Unserializable Objects to DiskThis vulnerability occurs when a J2EE application framework attempts to save objects to disk that cannot be properly serialized, risking application failure.
CWE-595Comparison of Object References Instead of Object ContentsThis vulnerability occurs when code incorrectly checks if two object references point to the same memory location, rather than comparing the actual data or values contained within the objects. This mistake prevents the software from correctly identifying when two separate objects hold equivalent content.
CWE-596DEPRECATED: Incorrect Semantic Object ComparisonThis CWE entry has been retired. It was originally created to describe a specific type of bug where code incorrectly compares two objects that should be considered the same, but the description was too vague and overlapped with other weaknesses. It has been consolidated into CWE-1023.
CWE-597Use of Wrong Operator in String ComparisonThis vulnerability occurs when a developer incorrectly compares string values, typically by using reference equality operators (like == or !=) instead of dedicated string comparison methods (like .equals()).
CWE-598Use of GET Request Method With Sensitive Query StringsThis vulnerability occurs when a web application handles sensitive data, like passwords or session tokens, by passing them within the URL's query string using an HTTP GET request.
CWE-599Missing Validation of OpenSSL CertificateThis vulnerability occurs when an application uses OpenSSL but fails to properly verify server certificates by not calling SSL_get_verify_result(). Without this validation, the application may accept insecure or fraudulent certificates.

CWE-602Client-Side Enforcement of Server-Side SecurityThis vulnerability occurs when a server incorrectly trusts the client to enforce critical security rules, such as input validation or access controls, instead of performing these checks itself.
CWE-603Use of Client-Side AuthenticationThis vulnerability occurs when an application places its authentication logic solely within the client-side code, such as in a mobile app or web browser, without enforcing the same checks on the server. Attackers can bypass authentication by modifying the client to skip these checks entirely.
CWE-605Multiple Binds to the Same PortThis vulnerability occurs when a system's socket configuration allows multiple applications to bind to the same network port simultaneously. This can let a malicious process hijack or impersonate legitimate services running on that port.
CWE-606Unchecked Input for Loop ConditionThis vulnerability occurs when an application fails to properly validate or limit user-supplied values that control loop iterations. Without these checks, malicious input can force the program into an endless or excessively long loop, consuming system resources and leading to denial of service or application instability.
CWE-607Public Static Final Field References Mutable ObjectThis vulnerability occurs when a class exposes a public or protected static final field that points to a changeable object. Because the field's reference is constant but the object itself is not, malicious code or even accidental code in other packages can modify the object's contents, violating the intended immutability.
CWE-608Struts: Non-private Field in ActionForm ClassThis vulnerability occurs when an Apache Struts ActionForm class exposes a field without declaring it as private. This allows other parts of the application to directly read or modify the field's data, bypassing the intended setter and getter methods.
CWE-609Double-Checked LockingDouble-checked locking is an insufficient synchronization pattern where a program checks a resource's state, acquires a lock, and checks the state again before initialization, failing to guarantee thread safety across all systems.
CWE-61UNIX Symbolic Link (Symlink) FollowingThis vulnerability occurs when a software application opens files or directories without properly checking if they are symbolic links (symlinks). If an attacker can create or control a symlink, they can redirect file operations to locations outside the intended directory, potentially accessing or modifying unauthorized files.

CWE-66Improper Handling of File Names that Identify Virtual ResourcesThis vulnerability occurs when software incorrectly processes a filename that points to a 'virtual' resource—like a device, pipe, or internal system object—instead of a regular file. The application mistakenly performs file operations (like read, write, or copy) on this non-file resource, which can lead to crashes, data exposure, or unexpected system behavior.
CWE-662Improper SynchronizationThis vulnerability occurs when a multi-threaded or multi-process application allows shared resources to be accessed by multiple threads or processes simultaneously, without proper safeguards to enforce exclusive access.
CWE-663Use of a Non-reentrant Function in a Concurrent ContextThis vulnerability occurs when a program uses a function that is not safe for reentrancy within a concurrent environment, such as multi-threaded code or signal handlers. If another thread or signal handler interrupts and calls the same function, it can corrupt shared data, cause crashes, or create unpredictable behavior.

CWE-673External Influence of Sphere DefinitionThe application allows external parties to modify its security boundaries or trusted zones, which should be defined and controlled internally.
CWE-674Uncontrolled RecursionThis vulnerability occurs when an application fails to limit how deeply a function can call itself. Without proper controls, this uncontrolled recursion can exhaust system resources like memory or stack space, leading to crashes or denial-of-service.
CWE-675Multiple Operations on Resource in Single-Operation ContextThis vulnerability occurs when a software component performs the same action on a resource multiple times, even though the action is designed to be executed only once. This redundant execution can lead to unintended side effects, data corruption, or resource exhaustion.
CWE-676Use of Potentially Dangerous FunctionThis vulnerability occurs when code calls a function that can be dangerous if misused, but can also be used safely with proper precautions. The risk lies not in the function itself, but in how it's implemented.
CWE-680Integer Overflow to Buffer OverflowThis vulnerability occurs when a program calculates the size of memory to allocate, but an integer overflow in that calculation results in a much smaller buffer being created than intended. This undersized buffer can then be overflowed by subsequent operations, corrupting adjacent memory.
CWE-681Incorrect Conversion between Numeric TypesThis vulnerability occurs when a program converts a value from one numeric type to another (like a 64-bit integer to a 32-bit integer) and the conversion loses or misinterprets data. If these corrupted values are later used in security-critical operations—like calculating buffer sizes, checking permissions, or performing financial transactions—they can lead to crashes, incorrect behavior, or security bypasses.
CWE-682Incorrect CalculationThis vulnerability occurs when software performs a calculation that produces wrong or unexpected results, which are then used to make security decisions or manage critical resources.

CWE-794Incomplete Filtering of Multiple Instances of Special ElementsThis vulnerability occurs when an application receives data from a source but fails to remove or neutralize every instance of a potentially dangerous element before passing that data to another component.
CWE-795Only Filtering Special Elements at a Specified LocationThis vulnerability occurs when a security filter only checks for dangerous input patterns at specific, predefined locations within the data. It fails to scan the entire input stream, allowing malicious elements that appear outside the expected location to pass through and potentially harm downstream components.
CWE-796Only Filtering Special Elements Relative to a MarkerThis vulnerability occurs when software filters dangerous inputs or characters, but only checks for them in specific, expected locations (like the start or end of a string). It fails to detect and remove the same dangerous elements if they appear elsewhere in the data, allowing them to pass through to critical system components.
CWE-797Only Filtering Special Elements at an Absolute PositionThis vulnerability occurs when software checks for dangerous characters or patterns only at a fixed, hardcoded location in input data. Because it ignores these same elements if they appear anywhere else, attackers can bypass the filter by simply moving the malicious content to a different position.

Consider using either the File Handling Issues category (CWE-1219) or the class Use of Incorrectly-Resolved Name or Reference (CWE-706).
CWE-2277PK - API AbuseThis category represents one of the phyla in the Seven Pernicious Kingdoms vulnerability classification. It includes weaknesses that involve the software using an API in a manner contrary to its intended use. According to the authors of the Seven Pernicious Kingdoms, "An API is a contract between a caller and a callee. The most common forms of API misuse occurs when the caller does not honor its end of this contract. For example, if a program does not call chdir() after calling chroot(), it violates the contract that specifies how to change the active root directory in a secure fashion. Another good example of library abuse is expecting the callee to return trustworthy DNS information to the caller. In this case, the caller misuses the callee API by making certain assumptions about its behavior (that the return value can be used for authentication purposes). One can also violate the caller-callee contract from the other side. For example, if a coder subclasses SecureRandom and returns a non-random value, the contract is violated."

CWE-3617PK - Time and StateThis category represents one of the phyla in the Seven Pernicious Kingdoms vulnerability classification. It includes weaknesses related to the improper management of time and state in an environment that supports simultaneous or near-simultaneous computation by multiple systems, processes, or threads. According to the authors of the Seven Pernicious Kingdoms, "Distributed computation is about time and state. That is, in order for more than one component to communicate, state must be shared, and all that takes time. Most programmers anthropomorphize their work. They think about one thread of control carrying out the entire program in the same way they would if they had to do the job themselves. Modern computers, however, switch between tasks very quickly, and in multi-core, multi-CPU, or distributed systems, two events may take place at exactly the same time. Defects rush to fill the gap between the programmer's model of how a program executes and what happens in reality. These defects are related to unexpected interactions between threads, processes, time, and information. These interactions happen through shared state: semaphores, variables, the file system, and, basically, anything that can store information."
CWE-371State IssuesWeaknesses in this category are related to improper management of system state.
CWE-376DEPRECATED: Temporary File IssuesThis category has been deprecated. It was originally used for organizing the Development View (CWE-699), but it introduced unnecessary complexity and depth to the resulting tree. Consider using the File Handling Issues category (CWE-1219).
CWE-380DEPRECATED: Technology-Specific Time and State IssuesThis entry has been deprecated. It was originally used for organizing the Development View (CWE-699) and some other views, but it introduced unnecessary complexity and depth to the resulting tree.
CWE-381DEPRECATED: J2EE Time and State IssuesThis entry has been deprecated. It was originally used for organizing the Development View (CWE-699) and some other views, but it introduced unnecessary complexity and depth to the resulting tree.
CWE-387Signal ErrorsWeaknesses in this category are related to the improper handling of signals.
CWE-3887PK - ErrorsThis category represents one of the phyla in the Seven Pernicious Kingdoms vulnerability classification. It includes weaknesses that occur when an application does not properly handle errors that occur during processing. According to the authors of the Seven Pernicious Kingdoms, "Errors and error handling represent a class of API. Errors related to error handling are so common that they deserve a special kingdom of their own. As with 'API Abuse,' there are two ways to introduce an error-related security vulnerability: the most common one is handling errors poorly (or not at all). The second is producing errors that either give out too much information (to possible attackers) or are difficult to handle."
CWE-389Error Conditions, Return Values, Status CodesThis category includes weaknesses that occur if a function does not generate the correct return/status code, or if the application does not handle all possible return/status codes that could be generated by a function. This type of problem is most often found in conditions that are rarely encountered during the normal operation of the product. Presumably, most bugs related to common conditions are found and eliminated during development and testing. In some cases, the attacker can directly control or influence the environment to trigger the rare conditions.
CWE-3987PK - Code QualityThis category represents one of the phyla in the Seven Pernicious Kingdoms vulnerability classification. It includes weaknesses that do not directly introduce a weakness or vulnerability, but indicate that the product has not been carefully developed or maintained. According to the authors of the Seven Pernicious Kingdoms, "Poor code quality leads to unpredictable behavior. From a user's perspective that often manifests itself as poor usability. For an adversary it provides an opportunity to stress the system in unexpected ways."
CWE-399Resource Management ErrorsWeaknesses in this category are related to improper management of system resources.
CWE-4DEPRECATED: J2EE Environment IssuesThis entry has been deprecated. It was originally used for organizing the Development View (CWE-699) and some other views, but it introduced unnecessary complexity and depth to the resulting tree.
CWE-411Resource Locking ProblemsWeaknesses in this category are related to improper handling of locks that are used to control access to resources.
CWE-417Communication Channel ErrorsWeaknesses in this category are related to improper handling of communication channels and access paths. These weaknesses include problems in creating, managing, or removing alternate channels and alternate paths. Some of these can overlap virtual file problems and are commonly used in "bypass" attacks, such as those that exploit authentication errors.
CWE-418DEPRECATED: Channel ErrorsThis category has been deprecated because it redundant with the grouping provided by CWE-417.
CWE-429Handler ErrorsWeaknesses in this category are related to improper management of handlers.
CWE-438Behavioral ProblemsWeaknesses in this category are related to unexpected behaviors from code that an application uses.
CWE-442DEPRECATED: Web ProblemsThis entry has been deprecated. It was originally used for organizing the Development View (CWE-699) and some other views, but it introduced unnecessary complexity and depth to the resulting tree.
CWE-445DEPRECATED: User Interface ErrorsThis weakness has been deprecated because it was a duplicate of CWE-355. All content has been transferred to CWE-355.
CWE-452Initialization and Cleanup ErrorsWeaknesses in this category occur in behaviors that are used for initialization and breakdown.
CWE-461DEPRECATED: Data Structure IssuesThis entry has been deprecated. It was originally used for organizing the Development View (CWE-699) and some other views, but it introduced unnecessary complexity and depth to the resulting tree.
CWE-465Pointer IssuesWeaknesses in this category are related to improper handling of pointers.
CWE-4857PK - EncapsulationThis category represents one of the phyla in the Seven Pernicious Kingdoms vulnerability classification. It includes weaknesses that occur when the product does not sufficiently encapsulate critical data or functionality. According to the authors of the Seven Pernicious Kingdoms, "Encapsulation is about drawing strong boundaries. In a web browser that might mean ensuring that your mobile code cannot be abused by other mobile code. On the server it might mean differentiation between validated data and unvalidated data, between one user's data and another's, or between data users are allowed to see and data that they are not."
CWE-490DEPRECATED: Mobile Code IssuesThis entry has been deprecated. It was originally used for organizing the Development View (CWE-699) and some other views, but it introduced unnecessary complexity and depth to the resulting tree.
