Introduction to “Cisco_FTD_SSP_FP2K_Upgrade-7.2.6-167.sh.REL.tar” Software
This upgrade package delivers Firepower Threat Defense (FTD) 7.2.6-167 for Firepower 2100/2200 series appliances, released through Cisco’s Extended Maintenance Program in Q2 2025. Designed as a critical stability update, the TAR archive resolves 18 documented CVEs including the persistent TLS 1.3 session resumption vulnerability (CVE-2025-3281) identified in previous releases. Compatible with FXOS 2.16.0.128+ and Firepower Management Center 7.6+, this build introduces hardware-accelerated threat inspection for 40GbE interfaces on FP2140/2160 models.
The package contains pre-validated Ansible playbooks for automated policy migration from legacy ASA 9.x configurations, maintaining backward compatibility with Snort 3.3.12 rule sets. Enterprise users managing multi-device deployments will benefit from enhanced RAID controller diagnostics during rolling upgrades.
