CWE-447 (在UI中的未实现或未支持特性) — Vulnerability Class 3

CWE-447 represents a deceptive interface weakness where a user interface element implies the presence of a security feature, such as encryption or authentication, while the underlying backend logic remains unimplemented. Attackers typically exploit this discrepancy by interacting with the visible control, assuming their actions are protected, which leads to a false sense of security. Consequently, sensitive data may be transmitted in plaintext or critical operations proceed without necessary validation, exposing the system to interception or unauthorized access. Developers can prevent this vulnerability by ensuring strict synchronization between frontend indicators and backend implementations. This requires rigorous code reviews to verify that every UI toggle or status message corresponds to an active, functioning security mechanism, thereby eliminating the risk of misleading user feedback and ensuring consistent security posture across the application.
