CWE-267 (特权定义了不安全动作) — Vulnerability Class 42

CWE-267 represents a design flaw where a defined privilege, role, or capability inherently permits unsafe actions that were not originally intended by the system architects. This weakness arises when the scope of a permission is overly broad or poorly defined, allowing authorized entities to execute operations that compromise security or integrity. Attackers typically exploit this by leveraging legitimate credentials to perform unauthorized activities, such as accessing sensitive data or modifying system configurations, because the privilege itself grants excessive capabilities. Developers can mitigate this risk by adhering to the principle of least privilege, ensuring that each role is granted only the minimum permissions necessary for its specific function. Rigorous threat modeling and regular code reviews help identify and restrict unintended action paths within privilege definitions, thereby preventing abuse even when assigned to correct entities.
