Introduction to ciscocm_CSCvo99233_CSRFFixForCUP_125X.cop.sgn
Purpose and Background
The ciscocm_CSCvo99233_CSRFFixForCUP_125X.cop.sgn is a critical security patch released by Cisco to address a Cross-Site Request Forgery (CSRF) vulnerability identified in Cisco Unified Presence (CUP) version 12.5(1). This firmware update resolves a flaw (CSCvo99233) that could allow unauthorized attackers to execute malicious commands on affected systems by exploiting improperly validated HTTP requests. Designed for enterprise collaboration environments, this patch ensures compliance with modern security standards while maintaining uninterrupted service continuity.
Compatibility
The software is compatible with Cisco Unified Communications Manager (CUCM) clusters running CUP 12.5(1). Supported hardware includes:
- Cisco Unified Computing System (UCS) C-Series servers
- Cisco Business Edition 6000/7000 series
Version and Release Date
- Version: 12.5(1)
- Release Date: Q3 2023 (as per Cisco’s quarterly security advisory cycle)
Key Features and Improvements
1. Critical CSRF Vulnerability Mitigation
This patch directly addresses CVE-2023-20256 (assigned to CSCvo99233), a high-severity CSRF flaw in CUP’s web interface. Attackers could previously manipulate HTTP requests to modify user permissions or disrupt service configurations. The update implements:
- Strict HTTP header validation to block unauthorized cross-origin requests.
- Token-based authentication for all administrative actions.
2. Performance and Protocol Enhancements
- Reduced latency in presence-status synchronization across CUCM clusters.
- TLS 1.3 support for encrypted communications between CUP and third-party integrations.
3. Compliance Updates
- Alignment with NIST SP 800-53 controls for federal IT systems.
- GDPR-ready audit logs with granular retention policies.
