Introduction to Cisco_FTD_SSP_Upgrade-7.0.3-37.sh.REL.tar
This cumulative security update addresses critical vulnerabilities in Cisco Firepower Threat Defense (FTD) 7.0.3 deployments for Secure Firewall Platform (SSP) appliances. Designed for 2100/4100 series hardware, the patch resolves 5 CVEs identified in Cisco’s Q4 2024 security advisory, including memory leakage in SSL decryption modules and policy synchronization conflicts in multi-device management environments. The “-37” build suffix indicates enhanced cloud integration capabilities with Cisco SecureX threat intelligence feeds.
Compatible with Firepower Management Center (FMC) 7.4+ and Cisco Defense Orchestrator (CDO) 3.1+, this maintenance release follows Cisco’s quarterly security update cycle. The update optimizes resource allocation for environments handling over 20Gbps of encrypted traffic while maintaining backward compatibility with existing threat detection policies.
