Introduction to ciscocm_CSCvo99233_CSRFFixForCUP_125X.cop.sgn
The ciscocm_CSCvo99233_CSRFFixForCUP_125X.cop.sgn is an official Cisco software patch designed to resolve a critical Cross-Site Request Forgery (CSRF) vulnerability identified in Cisco Unified Presence (CUP) deployments running version 12.5(1)X. This vulnerability, tracked under Cisco bug ID CSCvo99233, could allow unauthorized attackers to execute malicious actions by exploiting unsecured administrative interfaces.
Cisco released this patch as part of its ongoing commitment to addressing security risks in its Unified Communications ecosystem. The fix applies specifically to CUP servers integrated with Cisco Unified Communications Manager (CUCM) environments. Administrators managing CUCM clusters with CUP functionality must prioritize this update to mitigate potential security breaches.
Key Features and Improvements
The ciscocm_CSCvo99233_CSRFFixForCUP_125X.cop.sgn introduces critical security enhancements:
-
CSRF Vulnerability Mitigation
- Addresses CVE-2024-3355, a high-severity CSRF flaw in CUP’s web administration portal. Attackers could manipulate authenticated administrators into unknowingly executing unauthorized commands, such as modifying user privileges or service configurations.
- Implements anti-CSRF tokens to validate legitimate user requests, blocking unauthorized command injections.
-
Session Management Enhancements
- Strengthens session timeout policies for administrative accounts to reduce exposure windows.
- Enforces stricter validation of HTTP referrer headers to prevent cross-origin request attacks.
-
Compatibility with CUCM 12.5(1)SU6
- Validated for integration with CUCM version 12.5(1)SU6 and later, ensuring seamless deployment in existing clusters.
-
Minimal Service Disruption
- The patch applies without requiring a full system restart, maintaining uptime for mission-critical communication services.
Compatibility and Requirements
The following table outlines supported platforms and prerequisites for deploying the patch:
| Component | Supported Versions |
|---|---|
| Cisco Unified Presence (CUP) | 12.5(1)X (pre-patch baseline) |
| Cisco Unified CM (CUCM) | 12.5(1)SU6 or later |
| Operating System | Cisco-approved VMware ESXi 6.7/7.0 |
| Hardware | UCS C-Series servers, M5/M6 blades |
Important Notes:
- The patch is incompatible with CUP deployments running versions earlier than 12.5(1)X. Administrators must first upgrade to the baseline version.
- Verify VMware tools and UCS firmware compatibility using Cisco’s Interoperability Matrix Tool before installation.
