Introduction to Cisco_FTD_SSP_FP1K_Patch-7.1.0.3-108.sh.REL.tar

This hotfix package addresses critical vulnerabilities and operational improvements for Cisco Firepower Threat Defense (FTD) software running on Firepower 1000 Series appliances. Designed for SSP (Secure Firewall Platform) deployments, the patch resolves 9 documented CVEs while optimizing traffic inspection capabilities for enterprise networks. Cisco released this update in Q3 2024 as part of its quarterly security advisory cycle, with specific focus on mitigating directory traversal risks in web service interfaces.

Compatible with FTD versions 7.1.x, this hotfix maintains continuity with Cisco’s Adaptive Security Appliance (ASA) feature sets while enhancing next-generation firewall capabilities. The patch applies to both physical Firepower 1010/1140 appliances and virtual FTD instances managed through Firepower Management Center (FMC).
