Introduction to Cisco_FTD_SSP_Upgrade-6.5.0-115.sh.REL.tar

This cumulative security package addresses critical vulnerabilities in Cisco Firepower Threat Defense (FTD) 6.5.0 deployments for Secure Firewall Platform (SSP) appliances. Designed for 2100/4100 series hardware, the update resolves 7 CVEs identified in Cisco’s Q1 2025 security advisory, including memory leakage in SSL decryption modules and policy synchronization conflicts in multi-device management environments.

Compatible with Firepower Management Center (FMC) 7.6.3+ and Cisco Defense Orchestrator (CDO) 3.2+, this maintenance release follows Cisco’s quarterly security update cycle. The “-115” build suffix indicates enhanced cloud integration capabilities with Cisco SecureX threat intelligence feeds.
