Mitigating Controls

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

AU-5 Response to Audit Logging Process Failures
addresses: CWE-755

Provides defined handling (alert and additional actions) for the exceptional condition of audit logging failure.

CP-12 Safe Mode
addresses: CWE-755

Supplies a concrete handling action (safe mode) for exceptional conditions, mitigating risks from improper or absent handling that could allow continued attacks.

CP-3 Contingency Training
addresses: CWE-755

By preparing users for contingency scenarios, the control promotes proper handling of exceptional conditions instead of default or unsafe behaviors.

CP-5 Contingency Plan Update
addresses: CWE-755

An updated contingency plan defines current actions for exceptional conditions, reducing the window for attackers to exploit improper handling leading to system failure.

IR-1 Policy and Procedures
addresses: CWE-755

Procedures ensure proper handling of exceptional conditions to support effective incident response.

IR-3 Incident Response Testing
addresses: CWE-755

Incident response testing confirms proper handling of exceptional conditions to limit exploit impact.

IR-7 Incident Response Assistance
addresses: CWE-755

Gives users guidance on incident handling, reducing improper handling of exceptional conditions that could stem from exploited weaknesses.

SC-24 Fail in Known State
addresses: CWE-755

Enforces structured response to exceptional conditions so the system cannot remain in an unsafe state.

Hardening callouts derived

DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.

  • No fine-grained STIG row for CWE-755, a class-level weakness. Rules are authored against its narrower children: CWE-274, CWE-280, CWE-333.
