CWE-424 (对候选路径的不恰当保护) — Vulnerability Class 28

CWE-424, Improper Protection of Alternate Path, is a security weakness where a system fails to adequately secure all potential access routes to restricted resources or functionality. This vulnerability typically arises when developers implement access controls for primary interfaces but neglect secondary channels, such as administrative backdoors, debug modes, or alternative API endpoints. Attackers exploit this oversight by bypassing standard authentication mechanisms through these unprotected alternate paths, gaining unauthorized access to sensitive data or system privileges. To mitigate this risk, developers must adopt a comprehensive security architecture that enforces consistent access control policies across every possible interaction point. This involves rigorous threat modeling to identify all entry vectors, coupled with automated testing to verify that no alternate paths remain exposed. By ensuring uniform protection standards, organizations can prevent attackers from circumventing security measures through overlooked system components.
