Introduction to “Cisco_FTD_SSP_FP1K_Upgrade-6.7.0-65.sh.REL.tar” Software
The Cisco_FTD_SSP_FP1K_Upgrade-6.7.0-65.sh.REL.tar is an essential upgrade package for Cisco Firepower 4100 Series appliances running Firepower Threat Defense (FTD) software. Released in Q1 2025, this maintenance update resolves 12 critical CVEs identified in previous FTD versions while introducing hardware-specific optimizations for the Secure Firewall 4100/9300 chassis platform.
This shell-relocatable archive enables seamless migration from FTD 6.6.x to 6.7.x code trains without requiring full system reimaging. The “FP1K” designation confirms compatibility with Firepower 4110/4120/4140 models equipped with SSP-10/20/40 security modules. Enterprise users managing clustered deployments will benefit from the package’s non-disruptive upgrade capability during production hours.
