Introduction to UCSInstall_CER_15.0.1.11900-15.sha512.iso
This SHA512-validated installation package provides critical security updates for Cisco Emergency Responder (CER) 15.0.1 systems, addressing vulnerabilities identified in NIST Special Publication 800-175B compliance audits. Designed for enterprises requiring CJIS-compliant emergency communication systems, the ISO file contains FIPS 140-3 validated cryptographic modules and firmware patches for Cisco Unified Computing System (UCS) C-Series servers.
The update bundle resolves CVE-2025-11900 session hijacking vulnerabilities in CER’s location-based routing protocols while maintaining backward compatibility with Cisco Unified Communications Manager 15.0 SU1 and later. Certified for deployment on UCS C220 M6 rack servers with TPM 2.0 chipsets, it implements quantum-resistant encryption algorithms for SIP emergency call authentication.
