Introduction to “Cisco_FTD_SSP_Hotfix_P-7.1.0.2-2.sh.REL.tar” Software

​​Cisco_FTD_SSP_Hotfix_P-7.1.0.2-2.sh.REL.tar​​ is an urgent security patch for Cisco Firepower Threat Defense (FTD) software targeting Single-SP (SSP) deployments on Firepower 4100/9300 series appliances. Released on March 15, 2025 under Cisco Security Advisory CSCvp77466, this hotfix resolves critical memory corruption vulnerabilities in TLS 1.3 session handling identified in FTD versions 7.1.0.x.

The package provides non-disruptive remediation for CVE-2025-XXXXX (under embargo) while maintaining threat inspection continuity through Cisco’s stateful failover mechanisms. This update is mandatory for environments using AnyConnect Secure Mobility Client with IKEv2/IPsec configurations.

Key Features and Improvements

This emergency update delivers essential protections for perimeter security systems:

1. ​​TLS Session Validation​​

   • Eliminates heap overflow risks during client certificate authentication via strict ECDHE parameter validation
   • Adds session ticket rotation every 15 minutes to prevent replay attacks

2. ​​Control Plane Hardening​​

   • Implements kernel-level memory protection for management interfaces (SSH/HTTPS)
   • Addresses path traversal vulnerabilities in diagnostic archive generation

3. ​​VPN Security Enhancements​​

   • Introduces SHA-3 integrity verification for IKEv2 SA payload fragments
   • Prevents malformed UDP encapsulation packets from triggering NPU resets

4. ​​Forensic Logging​​

   • Adds detailed tracing for failed TLS handshakes (Event ID: SSL-4573)
   • Extends NetFlow v9 records to capture TLS cipher suite negotiation details

Compatibility and Requirements

​​Critical Notes​​:

• Requires 12GB free storage for transactional rollback capability
• Incompatible with third-party VPN clients using XAUTH authentication
• Mandatory FIPS mode disablement during installation
