CWE-279 (不安全的运行时授予权限) — Vulnerability Class 15

CWE-279 represents a critical configuration weakness where software incorrectly assigns execution permissions to objects, violating the user’s intended security policy. This flaw typically arises when developers fail to properly validate or apply access control lists during runtime, resulting in files or processes inheriting overly permissive settings. Attackers exploit this by manipulating these misconfigured permissions to escalate privileges, execute unauthorized code, or access sensitive data that should remain restricted. To mitigate this risk, developers must implement strict least-privilege principles, ensuring that permissions are explicitly defined and verified before assignment. Rigorous input validation, automated security testing, and comprehensive code reviews are essential practices to detect these discrepancies early. By enforcing precise permission controls and regularly auditing system configurations, organizations can prevent unintended access, thereby maintaining the integrity and confidentiality of their digital assets against potential exploitation.
