Introduction to ciscocm.postUpgradeCheck-00045.k4.cop.sha512

This critical validation package provides automated post-upgrade diagnostics for Cisco Unified Communications Manager (CUCM) 14.x environments, designed to ensure system integrity after major version migrations. Released on May 10, 2025 as part of Cisco’s Q2 maintenance cycle, the tool performs 78 essential checks spanning service configurations, certificate chains, and database consistency. The SHA-512 cryptographic verification ensures file integrity during deployment, aligning with Cisco’s Enhanced Software Validation Framework for collaboration systems.

Key Features and Improvements

    • Detects mismatched TLS 1.3 cipher suite configurations between CUCM nodes
    • Validates SIP trunk security profiles against NIST SP 800-52 Rev.3 standards

  2. ​​Security Enhancements​​

    • Identifies deprecated SHA-1 certificates in call processing subsystems
    • Flags unpatched CVE-2023-20048 vulnerabilities in FTD integration modules

  3. ​​Performance Optimization​​

    • Reduces database consistency check duration by 35% through optimized SQL queries
    • Supports parallel validation of up to 5 cluster nodes simultaneously

  4. ​​Protocol Compliance​​

    • Verifies SSHD host-key algorithm configurations per RFC 8332 specifications
    • Ensures proper implementation of hmac-sha2-512 message authentication codes
