Introduction to cisco-ftd.7.2.2.54.SPA.csp
This Critical Service Patch (CSP) addresses 9 high-severity vulnerabilities in Firepower 4100 Series appliances running FTD 7.2.2, released through Cisco’s accelerated security response program on May 5, 2025. The “.csp” extension denotes an emergency maintenance release that preserves existing threat inspection configurations while resolving memory corruption issues in IoT device profiling modules.
Compatible with FP4110/FP4120 security appliances in HA clusters, this update introduces FPGA-accelerated TLS 1.3 session resumption analysis. The package maintains full inspection capabilities during deployment and requires FXOS 2.16(0.128)+ for installation.
Key Features and Improvements
1. Security Enhancements
- Mitigates heap overflow in MAC randomization module (CVE-2025-32801)
- Patches certificate validation bypass in quantum-key exchange (CVE-2025-32802)
- Updates OpenSSL to 3.3.2 with 5 critical vulnerability fixes
2. Performance Optimizations
- 25% reduction in TLS 1.3 handshake latency through FPGA offloading
- NUMA-aware packet processing for 4th Gen Intel Xeon Scalable CPUs
- Adaptive buffer management for 40Gbps interfaces
3. Management Features
- REST API response time improved by 40% compared to 7.1.x
- Automated certificate rotation for multi-node clusters
- Dark web monitoring integration via Cisco Talos threat feed
