What is CWE-1263?

This vulnerability occurs when a device or system has areas meant to be physically secure, but the safeguards in place are too weak to stop someone with direct physical access from reaching restricted components or data.
Physical security flaws happen when the locks, seals, enclosures, or tamper-proofing on a device are not strong enough for its intended use. A consumer router, a medical implant, and an industrial control panel all need different levels of protection. Choosing the right physical barrier—like a robust casing or tamper-evident seals—is the first critical step in the design process. However, selecting a good mechanism isn't enough; it must be correctly implemented during manufacturing and assembly. A weak point, such as a poorly installed screw or an easily bypassed panel, can render the entire protection scheme useless. Ultimately, physical security fails when the design, implementation, and production do not work together to create a unified defense against hands-on tampering.

Cómo lo explotan los atacantes

Ruta del atacante paso a paso

  1. 1

    Identifica una ruta de código que maneje entrada no confiable sin validación.

  2. 2

    Crea un payload que ejercite el comportamiento inseguro — inyección, traversal, overflow o abuso de lógica.

  3. 3

    Envía el payload a través de una solicitud normal y observa la reacción de la aplicación.

  4. 4

    Itera hasta que la respuesta filtre datos, ejecute código del atacante o escale privilegios.

Ejemplo de código vulnerable

Vulnerable pseudo

MITRE no ha publicado un ejemplo de código para esta CWE. El patrón siguiente es ilustrativo — consulta Recursos para referencias canónicas.

Vulnerable pseudo 
// Example pattern — see MITRE for the canonical references.
function handleRequest(input) {
  // Untrusted input flows directly into the sensitive sink.
  return executeUnsafe(input);
}
Ejemplo de código seguro

Secure pseudo

Seguro pseudo 
// Validate, sanitize, or use a safe API before reaching the sink.
function handleRequest(input) {
  const safe = validateAndEscape(input);
  return executeWithGuards(safe);
}
What changed: the unsafe sink is replaced (or the input is validated/escaped) so the same payload no longer triggers the weakness.
Lista de prevención

How to prevent CWE-1263

  • Architecture and Design Specific protection requirements depend strongly on contextual factors including the level of acceptable risk associated with compromise to the product's protection mechanism. Designers could incorporate anti-tampering measures that protect against or detect when the product has been tampered with.
  • Testing The testing phase of the lifecycle should establish a method for determining whether the protection mechanism is sufficient to prevent unauthorized access.
  • Manufacturing Ensure that all protection mechanisms are fully activated at the time of manufacturing and distribution.
Señales de detección

How to detect CWE-1263

SAST High

Ejecuta análisis estático (SAST) sobre el código buscando el patrón inseguro en el flujo de datos.

DAST Moderate

Ejecuta pruebas dinámicas de seguridad de aplicaciones (DAST) contra el endpoint en vivo.

Runtime Moderate

Vigila los logs en tiempo de ejecución para detectar trazas de excepción inusuales, entradas malformadas o intentos de bypass de autorización.

Code review Moderate

Revisión de código: marca cualquier código nuevo que maneje entrada desde esta superficie sin usar los helpers validados del framework.
