CVE-2023-41151

Updated contingency plans include current procedures to detect, contain, and recover from resource exhaustion, limiting an attacker's ability to sustain impact from uncontrolled consumption.

MTTF monitoring plus ready substitutes directly mitigate sustained resource exhaustion by allowing component swap before or at failure.

Limiting concurrent sessions directly prevents uncontrolled resource consumption by capping the number of active sessions per user or account.

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

Analysis identifies uncontrolled resource consumption indicative of denial-of-service or abuse attempts.

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

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

Contingency plan testing includes resource exhaustion scenarios to verify recovery, making it harder for attackers to sustain exploits that cause uncontrolled consumption.

Pre-agreed severity-based prioritization and resource allocation during incident triage reduce the likelihood that an attacker-induced resource exhaustion will overwhelm the organization before corrective action is taken.

Documented operating procedures may specify exception handling but do not guarantee implementation.

Early notification of anomalous resource consumption or system malfunctions enables throttling or isolation before availability is lost.

Logging captures unhandled exceptions, aiding detection but not preventing the weakness.

Monitoring can surface unhandled exceptions but does not enforce proper handling.

A.8.20 implements network-level protections (firewalls, segmentation, protocol hardening, monitoring, authentication of systems/devices) that can limit abuse of a resource-consuming weakness but do not stop the weakness from being exploitable; the flaw remains present in the product and can still be triggered from an authorized or internal context.
