Introduction to Cisco_FTD_SSP_FP1K_Patch-7.2.5.1-29.sh.REL.tar Software
This critical security patch addresses vulnerabilities identified in Cisco Firepower Threat Defense (FTD) software for 1000 Series appliances. Designed for deployment on Firepower 4100/FTD 2100-3100 platforms, the hotfix resolves multiple CVEs while maintaining compatibility with FXOS 2.12.x environments.
The 7.2.5.1-29 release specifically targets directory traversal vulnerabilities in web services interfaces (CVE-2020-3452) and enhances Secure Boot validation protocols originally impacted by the Thrangrycat hardware exploit (CVE-2019-1649). Cisco TAC recommends immediate deployment for systems running FTD versions 7.0-7.2.5 due to active exploit risks.
