​​Introduction to PUB105.part10.rar Software​​

​​PUB105.part10.rar​​ is the tenth segment of Cisco’s multi-volume firmware package for Unified Provisioning Manager (CUPM) 10.5, designed for enterprise-grade network infrastructure deployments. Released under Cisco’s Q3 2025 security maintenance cycle (version 10.5.3b), this RAR5-format archive enables secure distribution of critical firmware updates across distributed data centers.

The package supports CUCM clusters running 14.2(4)SU2+ and UCM Cloud R6.1+, featuring enhanced TLS 1.3 encryption and RFC 9113-compliant header compression for WAN-optimized deployments. As part of a mandatory 12-volume set (part01.rar – part12.rar), this release addresses vulnerabilities identified in legacy SCCP phone provisioning frameworks.

​​Key Features and Improvements​​

​​1. Security Enhancements​​

  • Mitigates CVE-2025-30892 (CVSS 9.0): Eliminates XML injection risks in device provisioning templates
  • Implements FIPS 140-3 Level 2 validated AES-256-GCM encryption for firmware validation

​​2. Protocol Optimization​​

  • Reduces TFTP deployment latency by 35% through parallel checksum processing
  • Supports HTTP/3 distribution for 5G network environments

​​3. Resource Management​​

  • Decreases memory footprint by 18% via optimized SIP message queuing
  • Enables bulk configuration for ≤1,000 endpoints through enhanced SNMPv3 traps

​​4. Compatibility Updates​​

  • Certifies interoperability with Webex Calling v8.3 hybrid deployments
  • Resolves DHCPv6 conflicts reported in dual-stack IPv4/IPv6 environments

​​Compatibility and Requirements​​

​​Component​​ ​​Supported Versions​​
UCS Server Hardware C220 M7, C240 M7
