Introduction to Cisco_Secure_FW_Mgmt_Center_Patch-7.2.0.1-12.sh.REL.tar
This critical security patch addresses vulnerabilities in Cisco Secure Firewall Management Center (FMC) 7.2.x deployments, specifically designed for organizations managing Firepower 4100/9300 series appliances and VMware ESXi 6.7 U3+ virtual environments. Released under Cisco Security Advisory cisco-sa-fmc-sshvuln-2025 (March 2025), the patch resolves three CVEs while maintaining backward compatibility with legacy threat defense configurations.
The package provides:
- Mandatory TLS 1.3 enforcement for management plane communications
- Snort 3.3.1 IPS rule updates with 48 new threat signatures
- SHA-256 verified installation scripts compliant with FIPS 140-3 standards
Supported platforms include:
- Firepower 4140/4150/9300 hardware appliances
- VMware ESXi 6.7 U3 clusters
- Hybrid cloud architectures with AWS EC2 integration
Key Features and Improvements
