Introduction to ciscocm.ciscocm.V14SU3_CSCwe89928_sql-injection_C0194-1.zip

This cryptographic security patch addresses critical SQL injection vulnerabilities (CSCwe89928) identified in Cisco Unified Communications Manager (CUCM) 14.0 Service Update 3 environments. Designed under Cisco PSIRT advisory C0194-1, it implements parameterized query enforcement and input validation across CUCM administration portals to prevent unauthorized database access.

Validated for CUCM clusters running 14.0.1.2000-1 or later, the patch supports physical deployments on UCS C240 M5 servers and virtualized environments using VMware ESXi 8.0U3. Cisco officially released this emergency update on August 12, 2024, as part of its Q3 security maintenance cycle.

Key Features and Improvements

​​1. Vulnerability Mitigation​​

  • Eliminates SQL injection vectors in LDAP synchronization modules
  • Implements prepared statements for all SQL query operations
  • Restricts database permissions to read-only access for web UI components

​​2. Security Enhancements​​

  • SHA512 checksum validation for tamper-proof installations
  • TLS 1.3 encrypted distribution via Cisco CDN
  • Integration with Cisco Hypershield runtime protection framework

​​3. Compliance Updates​​

  • Meets NIST SP 800-53 revision 5 database security requirements
  • Aligns with ISO/IEC 27001:2022 access control standards
  • Implements PCI-DSS 4.0 parameterized query mandates

Compatibility and Requirements

Component Supported Versions Notes
CUCM 14.0.1.2000-1 to 14.0.3.1000-5 Requires SU3 baseline installation
IM&P 14.0.1.1000-4+ Presence service hardening
Virtualization VMware ESXi 8.0U3
