Introduction to Cisco_FTD_SSP_FP2K_Patch-7.1.0.3-108.sh.REL.tar
This emergency hotfix package addresses critical memory management vulnerabilities in Firepower Threat Defense (FTD) 7.1.0.3 deployments on Cisco Firepower 2100/4100 series appliances. Designed for enterprise network perimeter security, it resolves CVE-2020-3452 (CVSS 7.5) – a path traversal vulnerability in WebVPN services that allowed limited unauthorized file access.
Compatible exclusively with FTD 7.1.0.3 base images, this hotfix maintains operational continuity while hardening SSL/TLS inspection workflows. Cisco Security Vulnerability Response team released this patch on August 15, 2020, as part of their Extended Security Maintenance (ESM) commitments for high-risk vulnerabilities.
