11 vulnerabilities classified as CWE-691 (不充分的控制流管理). AI Chinese analysis included.
CWE-691 represents a critical architectural weakness where software fails to properly manage its execution path, allowing control flow to be altered unexpectedly. This vulnerability typically arises when applications lack robust state management or error handling mechanisms, enabling attackers to manipulate internal logic by injecting malicious inputs or exploiting race conditions. By bypassing intended security checks or triggering unintended code paths, adversaries can achieve unauthorized access, data corruption, or denial of service. To mitigate this risk, developers must implement strict state validation and enforce deterministic execution models. Utilizing formal verification techniques, comprehensive input sanitization, and rigorous exception handling ensures that the application’s control flow remains predictable and secure. Additionally, adopting defensive programming practices and conducting thorough code reviews helps identify and rectify logic flaws before deployment, thereby preventing attackers from exploiting these structural inconsistencies.
