​​Introduction to ciscocm.slm_quovadis_rootCA_decommission_v1.1.k4.cop.sha512​​

This critical security package addresses the phased decommissioning of QuoVadis root CA certificates in Cisco Unified Communications Manager (CUCM) environments. Designed per Cisco Security Advisory CSCwh65432, it systematically removes trust from deprecated certificates to comply with NIST SP 800-57 key rotation standards and mitigate MITM attack vectors.

The ​​v1.1.k4​​ iteration supports CUCM 14.0.1+ systems deployed under EU eIDAS compliance frameworks, with SHA-512 validation ensuring package integrity during distribution. Cisco’s Q1 2025 security bulletin confirms resolution of CVE-2025-12804 related to expired CA certificate handling.

​​Key Features and Improvements​​

  1. ​​Certificate Lifecycle Enforcement​​

    • Revokes 3 expired QuoVadis root CAs (QVCA 2016/2020/2023) from CUCM trust stores
    • Implements RFC 5280-compliant certificate revocation list (CRL) validation workflows

  2. ​​Crypto-agility Enhancements​​

    • Migrates TLS 1.2 sessions to ECDHE_ECDSA with secp384r1 curves
    • Updates FIPS 140-3 validated cryptographic modules

  3. ​​Compliance Automation​​

    • Generates audit-ready reports per ISO/IEC 27001 Annex A.10.1.2 controls
    • Preserves historical encrypted call records during CA transition
