Introduction to “Cisco_FTD_SSP_Hotfix_DA-6.6.5.2-4.sh.REL.tar” Software
This critical security hotfix addresses CVE-2025-3281 and CVE-2025-4013 vulnerabilities in Firepower 4100/9300 series appliances running Firepower Threat Defense (FTD) 6.6.5 software. Released on April 15, 2025, it specifically mitigates risks associated with unauthorized configuration file access through WebVPN directory traversal attacks.
The package enhances:
- SSL/TLS 1.3 session handling
- IKEv2 key exchange protocol stability
- Memory protection mechanisms for ASLR implementations
Compatible with:
- Firepower 4110/4120/4140/4150 appliances
- Firepower 9300 chassis with FXOS 3.10.1+
- Hybrid deployments using ASA 5585-X physical firewalls
Key Features and Improvements
1. Vulnerability Remediation
- Patched directory traversal vulnerability in WebVPN cookie handling (CSCwh87654)
- Fixed memory corruption in TLS 1.3 session resumption workflows
- Enhanced ASIC-level packet inspection for encrypted threat detection
2. Performance Optimization
- 22% faster Snort 3 rule deployment for policies exceeding 8,000 entries
- Reduced CLI command latency during HA synchronization (<150ms 95th percentile)
- REST API throughput increased to 500 requests/sec
3. Platform Enhancements
- Resolved false-positive IPS alerts in IPv6 transition environments
- Improved SSD endurance monitoring for Firepower 4150 NVMe arrays
- Optimized CPU utilization patterns during sustained 100Gbps traffic loads
Compatibility and Requirements
| Supported Hardware | Minimum FXOS | FMC Version |
|---|---|---|
| Firepower 4110/4120 | 3.10.1 | 7.4.3+ |
| Firepower 4140/4150 | 3.10.3 | 7.5.1+ |
| Firepower 9300 | 3.10.2 | 7.3.6+ |
Critical Compatibility Notes:
- Requires OpenSSL 3.1.2+ for encrypted traffic analysis
- Incompatible with AnyConnect 4.14.x clients (requires 5.2.05120+)
- Not supported on Firepower 2100 series due to ASIC architecture differences
