Introduction to Cisco_FTD_SSP_FP3K_Upgrade-7.2.0-82.sh.REL.tar
This upgrade package delivers Firepower Threat Defense (FTD) version 7.2.0-82 for Cisco Secure Firewall 3100/4100 series appliances. Designed as a feature-enriched maintenance release, it addresses 9 CVEs including CVE-2020-3452 – a critical directory traversal vulnerability in WebVPN interfaces. The update enhances TLS 1.3 inspection capabilities while maintaining backward compatibility with Firepower Management Center (FMC) 7.2+ deployments.
Cisco officially recommends this version for environments requiring NIST 800-218 compliance and AWS/Azure cloud integration. The package contains both FXOS platform updates and FTD security enhancements, ensuring unified threat prevention across physical/virtual attack surfaces.
