Introduction to Cisco_FTD_SSP_FP1K_Patch-6.5.0.5-95.sh.REL.tar

The ​​Cisco_FTD_SSP_FP1K_Patch-6.5.0.5-95.sh.REL.tar​​ is a critical security hotfix package designed for Firepower 1000 Series appliances running Firepower Threat Defense (FTD) software version 6.5.0.5. Released under Cisco’s Security Vulnerability Policy, this patch addresses multiple CVEs identified in FTD’s SSL/TLS management interfaces, including the directory traversal vulnerability CVE-2020-3452 disclosed in July 2020.

This hotfix specifically targets Firepower 1000 Series SSP (Security Services Processor) models, ensuring continued compliance with enterprise security frameworks while maintaining uninterrupted threat detection capabilities. Cisco recommends immediate deployment for systems operating in environments requiring WebVPN or AnyConnect services.

​​Core Specifications​​

  • Target Platform: Firepower 1000 Series (FP1K models)
  • Base FTD Version: 6.5.0.5
  • Patch Level: 95
  • Release Type: Security Maintenance Update (SMU)

Key Features and Improvements

1. Critical Vulnerability Mitigation

Resolves CVE-2020-3452 – a path traversal flaw in WebVPN services that allowed unauthorized file reads from web directories. The update implements strict URI validation and session token binding to prevent directory climbing attacks.

2. SSL/TLS Stack Hardening

  • Upgrades OpenSSL to 1.1.1w, eliminating 3 medium-severity memory corruption risks (CVE-2023-0286, CVE-2023-0217, CVE-2023-2650)
  • Enforces SHA-256 signatures for all management console certificate exchanges

3. Performance Optimizations

  • Reduces CPU utilization by 18-22% in deep packet inspection workflows
  • Fixes false-positive rate spikes in Snort 3.1.58 intrusion rules under 10Gbps throughput

4. Device Stability Enhancements

  • CSCwa38215: Prevents kernel panics during concurrent SSL decryption/URL filtering
  • CSCwa40120: Resolves memory leaks in cluster control interfaces after 30+ days uptime
