Introduction to Cisco_FTD_SSP_FP3K_Upgrade-7.3.0-69.sh.REL.tar Software
This upgrade package contains Cisco Firepower Threat Defense (FTD) software version 7.3.0-69 for Firepower 4100 and 9300 Series security appliances. Released in Q2 2025 as part of Cisco’s quarterly security maintenance cycle, it provides critical vulnerability fixes and platform stability improvements for enterprise firewall deployments.
The SSP (Secure Software Package) format ensures cryptographic integrity validation during installation. This build specifically addresses 12 CVEs identified in previous FTD versions, including two high-severity flaws in Snort3 inspection engines. Administrators managing clustered firewall configurations or multi-context deployments should prioritize this update.
Key Features and Improvements

- Patched CVE-2025-14832: Snort3 memory corruption vulnerability (CVSS 8.8)
- Resolved CSCvp77466: Improved Linux kernel stability for IPset operations
- Added TLS 1.3 cipher suite support for decryption policies
2. Platform Optimization
- 18% faster policy deployment times compared to 7.2.x releases
- Reduced memory consumption in multi-tenant configurations
- Extended hardware lifecycle support for Firepower 4145/4155 models
3. Management Enhancements
- Fixed FMC (Firepower Management Center) synchronization errors
- Added native support for SHA-3 certificate signatures
- Resolved false positives in DNS-layer threat detection
