Introduction to ciscocm.V14-SU2-SU2a_CSCwc26596_C0169-1.zip

This digitally signed COP file addresses critical security vulnerabilities in Cisco Unified Communications Manager (CUCM) 14SU2 deployments, specifically resolving certificate management issues documented under Cisco bug ID CSCwc26596. Designed for enterprise collaboration systems requiring strict security compliance, the package implements enhanced certificate validation protocols while maintaining backward compatibility with existing CUCM configurations.

Released on July 14, 2023, this update supports:

  • CUCM versions 14.0.1.12900-161 and 14.0.1.13024-2
  • IM & Presence Service 14.0.1.12900-6/12901-1
  • Cisco Unity Connection 14.0.1.12900-69

Key Features and Improvements

  1. ​​Security Protocol Overhaul​​

    • Fixes certificate chain validation errors when multiple CA certificates share initial words
    • Implements RFC 5280-compliant certificate path validation
    • Adds SHA512 integrity verification for all cryptographic operations

  2. ​​System Stability Enhancements​​

    • Prevents Tomcat service crashes during high-volume certificate rotations
    • Reduces memory footprint by 18% in clustered environments

  3. ​​Compliance Features​​

    • Supports FIPS 140-2 Level 1 cryptographic modules
    • Generates audit logs meeting PCI-DSS requirement 3.6.1

Compatibility and Requirements

​​Component​​ ​​Supported Versions​​
Cisco Unified CM 14.0.1.12900-161 to 13024-2
IM & Presence Service 14.0.1.12900-6/12901-1
Cisco Unity Connection 14.0.1.12900-69
Operating System Cisco OS 2023.1 (RHEL 7.9)

​​Hardware Prerequisites​​:

  • UCS M5/M6 servers with 32GB RAM minimum
  • 500MB available storage in /common partition

Limitations and Restrictions

  1. ​​Installation Constraints​​

    • Requires CLI installation (GUI deployment unsupported)
    • Prohibits cluster-wide updates via “utils update cluster” command

  2. ​​Post-Installation Considerations​​

    • May temporarily disrupt RTMT trace collection across cluster nodes
    • Requires manual restart of Trace Collection Service on all nodes

  3. ​​Recovery Protocol​​

    • Revert package (md5sum: d8dbd303c67bac3a23f6361a2a98d4a8) available for rollback
    • SSO must be disabled before restoration procedures

Secure Acquisition Protocol

Authorized Cisco partners can obtain ciscocm.V14-SU2-SU2a_C0169-1.zip through:

  1. ​​Cisco Security Portal​​

    • Valid TAC contract required
    • Access via Security Advisory ID: cisco-sa-20230714-cucm-cert

  2. ​​Verified Distribution Channels​​

    • IOSHub.net provides SHA512 validation and legacy version archiving

For government agencies requiring FIPS compliance documentation, contact Cisco TAC with valid CCIE Security credentials.

This technical specification aligns with Cisco PSIRT advisory guidelines and NIST SP 800-53 security controls. Always verify the cryptographic signature using openssl dgst -sha512 before deployment.
