Introduction to Cisco_FTD_Patch-6.7.0.1-13.sh.REL.tar Software
The Cisco_FTD_Patch-6.7.0.1-13.sh.REL.tar is a critical security maintenance package for Firepower Threat Defense (FTD) 6.7.x deployments, designed to address vulnerabilities in web service interfaces and VPN configurations. Released in Q4 2025 under Cisco’s Extended Security Maintenance program, this patch specifically targets Firepower 4100/9300 series appliances and FTDv virtual instances running in VMware/KVM environments.
This patch maintains compatibility with Cisco’s Adaptive Security Appliance (ASA) feature sets while introducing enhanced validation protocols for SSL/TLS certificate chains. It serves as a mandatory update for environments utilizing AnyConnect Secure Mobility Client 5.0+ with IKEv2/IPsec configurations.
