Introduction to “Cisco_FTD_SSP_FP1K_Patch-6.4.0.7-53.sh.REL.tar” Software

This hotfix package addresses critical security vulnerabilities and operational stability issues in Cisco Firepower Threat Defense (FTD) software 6.4.0 deployments on FP1K hardware platforms. Designed specifically for SSP (Secure Scalable Platforms) appliances like Firepower 4100 series, it enables administrators to maintain compliance with CVE-2020-3452 remediation requirements while preserving existing threat prevention configurations.

The 6.4.0.7-53 build focuses on maintaining service continuity for organizations using Firepower 2100/4100/9300 chassis with FP1K security modules. Compatible with FTD software version 6.4.0.x baseline installations, this cumulative patch was officially released in Q3 2024 according to Cisco’s quarterly security advisory cycle.
