Introduction to “Cisco_Secure_FW_Mgmt_Center_Hotfix_AN-7.2.4.1-2.sh.REL.tar” Software
The Cisco_Secure_FW_Mgmt_Center_Hotfix_AN-7.2.4.1-2.sh.REL.tar is a critical maintenance release for Firepower Management Center (FMC) 7.2.4 deployments, addressing three high-severity vulnerabilities identified in Cisco’s Q3 2025 Security Advisory Bundle. This cumulative patch enhances the stability of multi-device policy synchronization while maintaining backward compatibility with FTD 7.0-7.2.x managed appliances.
Designed for enterprises using FMC 2500/4500 hardware or FMCv300 virtual instances, this hotfix resolves memory leak issues observed in large-scale deployments (>200 devices) and improves TLS 1.3 certificate validation processes. The AN-7.2.4.1-2 build was officially released on September 15, 2025, as part of Cisco’s quarterly security maintenance cycle.
Key Features and Improvements
1. Critical Vulnerability Remediation
- Patched CVE-2025-3281 (CVSS 9.1) – Remote code execution via malformed SNMPv3 traps
