CVE-2025-13375 has a CVSS 3.1 base score of 9.8 (Critical). CVSS vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H. EPSS exploitation probability: 0.1%.

How to fix or mitigate CVE-2025-13375?

Within 24 hours: Identify all systems running IBM CCA 7.5.52 or 8.4.82 and isolate them from untrusted networks; enable enhanced logging and monitoring for suspicious access patterns. Within 7 days: Implement network-level access controls restricting CCA service ports to authorized systems only; apply any available interim security updates from IBM; engage IBM support for patch timeline. Within 30 days: Deploy patched CCA versions as soon as vendor releases are available; conduct forensic review for signs of compromise; execute full security assessment of affected systems.

DescriptionCVE.org

IBM Common Cryptographic Architecture (CCA) 7.5.52 and 8.4.82 could allow an unauthenticated user to execute arbitrary commands with elevated privileges on the system.

Executive ViewAI

Why It Matters

IBM CCA versions 7.5.52 and 8.4.82 contain a critical vulnerability allowing unauthenticated remote attackers to execute arbitrary commands with system-level privileges. Any organization running affected CCA versions faces immediate risk of complete system compromise, data exfiltration, and operational disruption without immediate mitigation.

Business Impact: Severe

Compensating Controls

Implement strict network segmentation to restrict access to IBM CCA services from untrusted networks; deploy Web Application Firewall (WAF) rules to block suspicious command payloads if CCA exposes web interfaces; disable or restrict remote access to CCA administrative functions; enforce authentication/authorization controls at network perimeter; implement continuous endpoint detection and response (EDR) monitoring; disable CCA services if not actively required until patch is available.

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.
