Introduction to Cisco_FTD_SSP_FP2K_Patch-7.4.2.2-28.sh.REL.tar
This hotfix package addresses critical vulnerabilities in Firepower Threat Defense (FTD) 7.4.x deployments for 2000/4000 series appliances with Secure Software Provisioning (SSP) architecture. The .tar file contains security updates resolving CVE-2025-0211 (directory traversal vulnerability) and CVE-2025-0472 (memory exhaustion flaw), both identified in Cisco’s Q2 2025 security advisories.
Designed for organizations requiring zero-downtime patching, this build maintains compatibility with Firepower Management Center (FMC) 7.6+ while introducing hardware-accelerated threat inspection capabilities for encrypted traffic analysis.
Key Features and Improvements
1. Vulnerability Mitigation
- Complete remediation for WebVPN directory traversal vulnerabilities
- Memory allocation fixes preventing denial-of-service (DoS) attacks
- Enhanced XML parser validation for management plane communications
2. Performance Enhancements
- 45Gbps sustained throughput on Firepower 4140 appliances
- 32% reduction in SSL decryption latency using Intel QAT v2.5
- Hot-patch deployment completes in <90 seconds without service interruption
3. Operational Upgrades
- REST API response times improved from 680ms to 210ms (avg)
- SNMPv3 engine ID persistence during high-availability failovers
- Pre-provisioned threat intelligence templates for FMC 7.6.2+
