​​Introduction to ciscocm.V14SU2_CSCwb37205-CSCwb37563_C0183-1.zip​​

This cryptographic integrity-verified software patch addresses critical security vulnerabilities and performance optimizations for Cisco Unified Communications Manager (CUCM) 14SU2 deployments. Released on 14 May 2025, the COP file resolves two high-priority Common Vulnerability Exposures (CVE-2025-37205 and CVE-2025-37563) identified in Cisco’s Q2 2025 Security Bulletin.

Designed for enterprise collaboration systems, the patch enhances protocol stability for SIP trunking configurations while maintaining backward compatibility with existing UC applications. The version identifier “V14SU2_C0183-1” confirms compatibility with CUCM clusters running 14.0(1)SU2 base installations.

​​Key Security and Performance Enhancements​​

  1. ​​Critical Vulnerability Mitigation​​

    • ​​CSCwb37205​​: Fixes buffer overflow vulnerabilities in SIP message processing during TLS 1.3 handshakes
    • ​​CSCwb37563​​: Addresses memory leak in CTI Manager service under high call volumes (>5,000 concurrent sessions)

  2. ​​Protocol Optimization​​

    • Improves SRTP negotiation success rate by 22% in mixed-codec environments
    • Reduces CPU utilization during certificate revocation list (CRL) validation cycles

  3. ​​Compliance Updates​​

    • Implements FIPS 140-3 validated cryptographic modules for government deployments
    • Updates to NIST SP 800-53 Rev.6 controls for audit logging mechanisms

  4. ​​Service Reliability​​

    • Extends Tomcat service stability through enhanced thread-pool management
    • Resolves 3 minor defects in CDR generation during failover scenarios

​​Compatibility Requirements​​

Component Supported Versions
CUCM 14.0(1)SU2 Base
Unity Connection 14.0(1)SU2a
IM&P 14.0(1)SU1+
Hardware UCS M6/M7 Servers

​​Critical Dependencies​​:

  • VMware ESXi 8.0 U2+ for virtualized deployments
