CVE-2023-21137

Requires detection and response to audit logging failures as an unusual or exceptional condition.

Implements detection of unusual or exceptional conditions followed by safe mode entry, reducing the window for exploitation of unchecked conditions.

Training ensures users perform required checks for unusual or exceptional conditions as part of contingency roles, limiting attacker leverage from skipped validations.

IR testing directly validates checks for unusual or exceptional conditions that could indicate security incidents.

Requires ongoing monitoring of organization-defined metrics and analysis, enabling checks for unusual or exceptional conditions.

Security testing routinely checks for unusual or exceptional inputs/conditions, identifying missing validation steps that flaw remediation then resolves.

Requires detection of unusual conditions followed by a controlled transition to the defined failure state.

MTTF determination forces explicit checks for conditions that precede predictable component failure.

Logging can record unhandled exceptions but does not prevent the weakness itself.

Monitoring may detect symptoms of unhandled conditions but does not eliminate the root weakness.

Secure development life cycle mandates exception handling and input validation that directly prevent missing checks for unusual conditions.

Application security requirements explicitly call for handling of exceptional conditions and error paths.

A.8.27 mandates security-by-design principles (fail securely, least privilege, distrust external input, security-oriented design reviews) that reach some but not most CWE-754 cases; many exceptional-condition checks live in low-level code paths outside architecture-level engineering.

Secure coding standards directly mandate proper checks for exceptional and unusual conditions.
