Introduction to ciscocm_CSCvo42306_CSRFFix_12_5X_v1.8.cop.sgn

This Cisco Options Package (COP) file addresses critical ​​CVE-2023-20198​​ vulnerabilities in Cisco Unified Communications Manager (CUCM) 12.5(x) systems, specifically targeting Cross-Site Request Forgery (CSRF) attack vectors in administrative web interfaces. Designed for on-premises deployments, it implements OWASP-recommended security headers and session token validation enhancements for Cisco Unified Reporting and Real-Time Monitoring Tool interfaces.

The “v1.8” designation confirms cumulative updates since its initial 2022 release, now supporting FIPS 140-3 validated cryptography modules for government/military installations. Compatible with virtualized and physical UCS servers running CUCM 12.5(1) SU3+, it maintains backward compatibility with Cisco Business Edition 6000/7000 series appliances.
