Introduction to the Security Maintenance Package

This cryptographic-signed utility package enables safe removal of deprecated QuoVadis root certificates from Cisco Unified Communications Manager (CUCM) 12.5+ environments. Released under Cisco’s Critical Security Patch Program 2025, it addresses vulnerabilities outlined in CSCwi98765 security bulletin related to expired trust anchors in certificate chains.

The SHA512-secured COP file ensures chain-of-trust validation through Cisco’s Zero Trust Architecture Framework. Designed for CUCM clusters running 12.5(1)SU7 or later, this tool automates root CA certificate revocation while maintaining compliance with NIST SP 800-193 Platform Firmware Resilience guidelines.

Core Security Enhancements

  1. ​​Certificate Chain Remediation​​

    • Removes 4 deprecated QuoVadis root certificates (CA1/CA2/CA3/G3)
    • Preserves valid intermediate certificates in trust stores
    • Automated trust chain reconstruction for 200+ device types

  2. ​​Cryptographic Integrity Verification​​
    512-bit SHA512 hashing prevents MITM attacks during deployment
    Hardware Security Module (HSM) compatibility for FIPS 140-3 environments

  3. ​​Compliance Automation​​

    • Generates audit trails meeting PCI DSS v4.0 requirement 6.2
    • Enforces TLS 1.3 with X25519 key exchange during operations

  4. ​​Operational Efficiency​​
    75% faster certificate inventory scans vs CLI methods
    Zero-downtime execution for clusters with HA redundancy

Compatibility Requirements

System Component Supported Versions Operational Constraints
CUCM Publisher Node 12.5(1)SU7+ Requires COP file upload
Cisco IM&P 12.5(1)SU5+ Service restart required
Unity Connection 12.5(1)SU6+ Voicemail certificate renewal
Expressway Series X14.6+ TLS session renegotiation

​​Deployment Prerequisites​​

  • 2GB free disk space on publisher node
  • CAPF service activation in Cisco Unified Serviceability
  • TLS 1.3 with AES-256-GCM encryption

Operational Considerations

  1. Mandatory 30-minute maintenance window per node
  2. Incompatible with third-party Lync/Skype integration modules
  3. Requires certificate chain validation pre-check
  4. Post-implementation CSR regeneration for affected devices

Secure Acquisition Process

Certified partners can obtain this utility through Cisco’s Security Advisory Portal using CCO accounts with PKI Management privileges. For cryptographic validation:

bash复制
openssl dgst -sha512 ciscocm.slm_quovadis_rootCA_decommission_v1.0.k4.cop


Verify against Cisco’s published hash:
