Introduction to Cisco_FTD_SSP_FP2K_Patch-7.2.5.1-29.sh.REL.tar Software
This cumulative security patch resolves 3 critical vulnerabilities (CVE-2025-20356 class risks) identified in Cisco Firepower Threat Defense (FTD) 7.2.5 deployments on Firepower 2100 series appliances. Designed as a mandatory update for environments using AnyConnect SSL VPN or IKEv2 remote access configurations, the patch implements memory protection mechanisms while maintaining backward compatibility with FMC 7.2.x management systems.
Compatible with Firepower 2110/2130/2140 hardware platforms running FXOS 2.16.1+, this release focuses on preventing directory traversal attacks through enhanced URI validation protocols. The software requires 200GB SSD free space and supports concurrent operation with Cisco SecureX threat intelligence feeds.
