Introduction to UCSInstall_CUP_10.5.1.11900-5.sgn.iso Software
The UCSInstall_CUP_10.5.1.11900-5.sgn.iso is a critical security enhancement package for Cisco Unified Communications Manager (UCM) IM & Presence Service deployments, designed to address cryptographic vulnerabilities in real-time collaboration systems. This ISO image integrates 15 security patches identified in Cisco’s 2024 Q4 Threat Response Report while maintaining backward compatibility with UCM clusters running version 10.5(1) or later.
Released in Q3 2024 as part of Cisco’s Extended Security Maintenance (ESM) program, this update specifically targets session encryption improvements for Jabber clients and Webex hybrid messaging services. It supports VMware virtualization environments on Cisco UCS C-Series servers (C220 M5/M6 and C240 M5/M6 models) with 64GB RAM or higher configurations.
Key Features and Improvements

- SIP/SIMPLE protocol exchanges
- Resolves critical vulnerabilities:
- CVE-2024-20356 (Persistent XSS in Cisco Unified IM)
- CVE-2024-20358 (Jabber certificate validation bypass)
Protocol Optimization
- 35% faster TLS 1.3 handshake negotiation for mobile clients
- Extended support for ECDSA-521 bit certificates in federation topologies
Hybrid Deployment Improvements
- Automatic synchronization between:
- Cisco Expressway Core 14.0.1+
- Webex Hybrid Message Service 3.1
- Unified diagnostic portal for cross-cluster presence status monitoring
