DescriptionCVE.org

Executive ViewAI

Why It Matters

Entrust nShield hardware security modules (HSM) contain a vulnerability allowing physically proximate attackers with elevated privileges to falsify tamper detection events, potentially masking unauthorized access or tampering. Organizations using affected nShield models must immediately assess their physical security posture and implement compensating controls, as no patch is currently available.

Business Impact: High

Compensating Controls

Implement strict physical access controls and badge/biometric authentication to HSM locations; enforce dual-control procedures requiring two authorized personnel for any physical HSM access; enhance environmental monitoring and closed-circuit video surveillance of HSM areas; increase frequency of tamper event log audits and forward logs to centralized immutable storage; disable remote management features if operationally feasible; consider air-gapped network segmentation for affected HSMs; establish regular key rotation schedules independent of tamper event validation.

What every action level means

Emergency Immediate action required. Criteria: CRITICAL + in CISA KEV (actively exploited) without patch, OR CRITICAL + EPSS > 30% without patch, OR CRITICAL + active threat signals without patch.

Act Now Prioritize within 24-48h. Criteria: in KEV with patch available, OR CRITICAL + public POC, OR HIGH + EPSS > 10%, OR CRITICAL + active threat, OR any CRITICAL severity.

This Week Schedule remediation this week. Criteria: HIGH severity (CVSS 7.0-8.9). Patch within normal change window.

This Month Plan within 30 days. Criteria: MEDIUM severity (CVSS 4.0-6.9), lower exploitation probability. Include in regular patch cycle.

Monitor Track and reassess. Criteria: LOW severity (CVSS 0.1-3.9), minimal exploitation risk. No immediate action needed.
