Introduction to Cisco_Secure_FW_Mgmt_Center_Upgrade-7.2.3-77.sh.REL.tar
This hotfix package addresses critical vulnerabilities in Cisco Firepower Management Center (FMC) 7.2.x deployments, specifically targeting command injection risks in backup workflows (CVE-2024-20275) and SQL injection flaws in policy synchronization interfaces (CVE-2024-20340). Released as part of Cisco’s Q2 2025 security maintenance cycle, it maintains backward compatibility with Firepower Threat Defense (FTD) 7.0.1-7.2.x devices while introducing enhanced TLS 1.3 inspection capabilities.
Designed for hybrid infrastructure management, the update supports physical appliances (Firepower 2100/9300 series) and virtual deployments on VMware ESXi 7.0+/KVM 6.2+ platforms. Cisco mandates this upgrade for environments requiring compliance with NIST SP 800-193 platform integrity standards.
Key Features and Improvements
1. Critical Security Updates
- CVE-2024-20275 Mitigation: Eliminates command injection vectors in cluster backup processes via sanitized user input validation.
- CVE-2024-20340 Resolution: Implements parameterized SQL queries to prevent unauthorized database access during policy synchronization.
2. Operational Enhancements
- TLS 1.3 Full Handshake Support: Enables RFC 8446 compliance with ECDHE-ECDSA-AES256-GCM-SHA384 cipher prioritization for SSL decryption workflows.
- Database Optimization: Reduces policy deployment latency by 22% through PostgreSQL index reorganization for large rule sets.
3. Platform Integration
- VMware vSphere 8.0 U2 Compatibility: Validates VM hardware version 20 support with paravirtualized SCSI controllers.
- Azure Stack Hub Readiness: Includes preconfigured ARM templates for hybrid cloud deployments.
Compatibility and Requirements
Supported Platforms
| FMC Model | Virtualization Platform | Minimum Resources |
|---|---|---|
| FMCv250 | VMware ESXi 7.0+ | 8 vCPUs, 24GB RAM |
| FMCv300 | KVM 6.2+ | 12 vCPUs, 32GB RAM |
| FMC 4500 | Physical Appliance | 16 cores, 64GB RAM |
Critical Constraints:
- Incompatible with AMD EPYC 7002-series CPUs due to AES-NI instruction set limitations.
- Requires OpenSSL 3.0.12+ for secure boot validation.
