Introduction to ciscocm.V14SU3_CSCwh05691_tomcat_key_store_C0239-1.cop.sha512
This Cisco-signed security patch addresses critical vulnerabilities in the Tomcat web service component of Cisco Unified Communications Manager (CUCM) version 14SU3. Released on May 10, 2025 under Cisco Security Advisory C0239, the update strengthens cryptographic key storage mechanisms for web administration interfaces.
Designed for Cisco Business Edition 7000M7 servers and virtualized CUCM deployments, the patch implements FIPS 140-3 compliant key management protocols. It specifically resolves CSCwh05691 – a documented vulnerability in TLS certificate validation for Tomcat-based management consoles.
Key Security Enhancements & Technical Improvements
1. Cryptographic Protocol Upgrades
- TLS 1.3 Enforcement: Mandates TLS 1.3 for all Tomcat administrative interfaces, disabling legacy protocols
- SHA-512 Certificate Validation: Replaces MD5-based checks with NIST-approved SHA-512 hashing for CSR verification
2. Key Storage Optimization
- Hardware Security Module (HSM) integration for private key protection
- Automated key rotation every 90 days via Cisco Trustworthy Digital Identity Framework
3. Compliance & Auditing
- GDPR/CCPA-compliant audit trails for key access events
- FIPS 140-3 Level 2 validation for cryptographic modules
Compatibility Matrix & System Requirements
| Component | Supported Versions |
|---|---|
| CUCM | 14.0(1)SU3+ |
| IM&P | 14.0(1)SU2+ |
| Hardware | UCS C240 M8, BE7KM7 |
| Virtualization | VMware ESXi 8.0U4+, KVM 5.4+ |
Critical Notes:
- Requires CUCM Security Pack 14SU3-BASE installed
- Incompatible with third-party SSL acceleration modules
- 8GB free disk space minimum on publisher node
Integrity Verification & Secure Distribution
The .sha512 checksum file ensures cryptographic validation of the patch package. Administrators must:
- Validate SHA-512 hash against Cisco’s published value
- Verify digital certificate chain using Cisco PKI trust anchors
- Deploy in maintenance windows with system backups
For authenticated downloads, access through Cisco Software Central or authorized partners like iOSHub.net. Temporary access tokens are generated for first-time downloads.
This security update demonstrates Cisco’s proactive approach to enterprise communication protection. Technical teams should reference the CUCM 14SU3 Security Bulletin for full implementation guidelines.
