Introduction to ciscocm.cuc.V14SU3_CSCwf62081-2.zip
This SHA512-validated software package provides critical security enhancements for Cisco Unity Connection (CUC) 14.0(1)SU3 deployments. Officially released on May 10, 2025, it addresses authentication protocol vulnerabilities identified in Cisco’s Q2 2025 security advisory cycle. The update specifically targets certificate management workflows in multi-node collaboration environments, ensuring compliance with NIST SP 800-131B cryptographic standards.
Key Features and Improvements
- Security Protocol Updates
- Resolves CSCwf62081 vulnerability in X.509 certificate chain validation logic
- Implements RFC 7469 Extended Validation Certificate requirements
- Enhances SHA512-based signature verification for SIP trunk configurations
- Authentication System Overhauls
- Strengthens TLS 1.3 handshake protocols for REST API endpoints
- Updates OpenSSL libraries to 3.2.1a (FIPS 140-3 compliant)
- Adds certificate revocation list (CRL) auto-refresh capabilities
- Administrative Control Enhancements
- Introduces granular permission controls for SSO certificate management
- Improves audit logging for cryptographic operations
- Enables automatic backup of pre-update security configurations
Compatibility and Requirements
| Component | Supported Versions | Minimum Patch Level |
|---|---|---|
| CUCM | 14.0(1)SU2a – 14.0(3) | 14.0(1.13024-2) |
| CUC | 14.0(1)SU3 | 14.0(1.12900-69 |
| IM&P | 14.0(1)SU1 – 14.0(2) | 14.0(1.12901-1 |
System Prerequisites:
- 500MB free space on primary CUC publisher node
- Cisco Prime Collaboration 12.9+ for centralized deployment
- Active NTP synchronization (±30ms tolerance)
Limitations and Restrictions
- Deployment Constraints
- Requires manual service restarts on all cluster nodes post-installation
- Incompatible with legacy SSO configurations using SHA1 signatures
- Operational Considerations
- Disables TLS 1.0/1.1 protocols by default during upgrade
- Requires reissuance of self-signed certificates older than 2048-bit RSA
