1. Introduction to Cisco_FTD_SSP_FP2K_Hotfix_Y-6.7.0.3-7.sh.REL.tar Software

This hotfix package addresses critical vulnerabilities in Cisco Firepower Threat Defense (FTD) 6.7.x deployments on Firepower 2000 Series security appliances. Released in Q3 2020 as part of Cisco’s Extended Security Maintenance cycle, the patch specifically resolves CVE-2020-3452 (CVSS 7.5) – a directory traversal vulnerability affecting WebVPN services, and CVE-2018-0101 (CVSS 10.0) – a double-free memory corruption flaw in SSL VPN handlers.

Designed for Firepower 2100/4100/9300 series hardware, this .REL.tar archive contains both security updates and performance enhancements validated through Cisco’s Secure Package Authentication protocol. The hotfix maintains compatibility with Firepower Management Center 6.7.x while introducing TLS 1.3 support for encrypted traffic inspection.
