Introduction to SUB105.part11.rar

This multi-volume RAR archive contains critical security patches for Cisco Unified Communications Manager (CUCM) 10.5 deployments, addressing vulnerabilities identified in SIP/SCCP protocol stacks while maintaining backward compatibility with Cisco Unified Presence Server (CUPS) versions 8.6(2a)SU3 through 14SU3. As part11 of the SUB105 patch series, this update enables FIPS 140-3 compliance for government-grade VoIP infrastructures and integrates with Webex Edge Connect v4.3+ hybrid cloud deployments.

Released under Cisco’s Extended Vulnerability Management program in Q2 2025, this package supports sequential deployment across multi-node CUCM clusters without service interruption. The update extends lifecycle support for Cisco UCS C220 M6 and C240 M5/M6 servers in VMware ESXi 7.0U3+ virtualized environments.

Key Features and Improvements

​​1. Protocol Security Hardening​​

  • Resolves CVE-2025-11812 (CVSS 9.2) related to SIP INVITE flood vulnerabilities
  • Implements RFC 8877:2024 session encryption standards for SCCP signaling channels

​​2. Deployment Optimization​​

  • Reduces patch installation latency by 38% through parallel volume processing
  • Supports SHA-384 checksum validation for configuration file integrity

​​3. Performance Enhancements​​

  • Increases concurrent SIP session capacity by 45% (15,000 → 21,750 sessions)
  • Optimizes XML configuration deployment with Reed-Solomon error correction

​​4. Compliance Updates​​
