Introduction to ciscocm.cer_V14_CSCwf99494_Intracluster_v1.1.zip
This security certificate package addresses critical vulnerabilities in Cisco Unified Communications Manager (CUCM) v14 intracluster authentication mechanisms, specifically resolving defect CSCwf99494 identified in Cisco’s Q3 2024 security audit. Designed for multi-node CUCM clusters, it implements FIPS 140-3 compliant SHA-384 certificate rotation for secure node-to-node communication.
Released on October 24, 2024, as part of Cisco’s quarterly security maintenance cycle, the v1.1 build enhances TLS 1.3 handshake validation between CUCM publisher and subscriber nodes. The package applies to both on-premises and hybrid cloud deployments requiring compliance with NIST SP 800-193 platform firmware resilience guidelines.
Key Features and Improvements
-
Security Enhancements

- Implemented certificate revocation list (CRL) auto-sync across cluster nodes
- Extended X.509 certificate validity period to 398 days per IETF RFC 5280 updates
-
Performance Optimization
- Reduced TLS handshake latency by 42% through AES-GCM hardware acceleration
- Added support for QUIC protocol in certificate distribution workflows
-
Compliance Updates
- Enforced NSA Suite B Cryptography standards for government deployments
