Introduction to “cisco-ftd.7.0.4.55.SPA.csp”
This software package delivers Firepower Threat Defense (FTD) 7.0.4.55 for Firepower 4100/9300 series appliances, specifically addressing CVE-2024-20356 – a critical memory leak vulnerability in IPsec VPN session handling. Designed for enterprise-grade threat prevention, it introduces hardware-accelerated TLS 1.3 cipher suites and improves SSL inspection throughput by 35% through AES-NI optimization.
Compatible with FXOS 2.14.1.131+ firmware, this Q4 2024 release supports both standalone deployments and high-availability clusters with sub-second failover capabilities. The package maintains backward compatibility with Firepower Management Center (FMC) 7.0.4.x while introducing enhanced REST API support for bulk policy deployments.
Key Features and Improvements
1. Critical Vulnerability Mitigation
- Resolves control plane memory exhaustion in IKEv2 processing (CSCsg58854)
- Eliminates false-positive intrusion events in Snort 3.1.22.0 rulesets
2. Throughput Optimization
- Achieves 40Gbps SSL inspection capacity on FP4115 appliances
- Reduces HA failover latency to <900ms through stateful session mirroring
3. Management Modernization
- Implements REST API batch processing for 500+ rule deployments
- Fixes SNMPv3 trap generation failures during traffic surges
