This vulnerability occurs when a software application either fails to use or incorrectly implements a built-in or library-provided input validation framework.
Modern programming languages and libraries offer robust validation frameworks designed to make input checking simpler and more consistent. When developers bypass or misconfigure these tools, they often have to write custom validation logic, which is error-prone and can leave gaps that attackers exploit. This manual approach also hurts code maintainability, as other developers might not recognize the scattered validation logic meant to replace the standard framework. While the missing framework itself isn't directly exploitable, it frequently leads to weak or inconsistent input sanitization downstream, creating openings for injection attacks or data corruption. Managing this at scale is difficult; an ASPM like Plexicus can help you track and remediate these architectural flaws across your entire stack, ensuring validation frameworks are used correctly to enforce security from the start.
Impact: Unexpected State
Unchecked input leads to cross-site scripting, process control, and SQL injection vulnerabilities, among others.
