​​Introduction to FGT_5001E-v6-build1803-FORTINET.out Software​​

This firmware package delivers critical security updates and performance optimizations for FortiGate 5001E next-generation firewalls running FortiOS 6.4.15. Released as part of Fortinet’s Q4 2024 security maintenance cycle, it addresses 12 CVEs while introducing hardware-specific optimizations for threat prevention throughput.

The build supports FGT-5001E hardware appliances with factory-default FortiOS 6.4.x installations, specifically designed for enterprises requiring stable long-term support (LTS) versions. Compatibility extends to both standalone and HA cluster configurations when running identical firmware across nodes.

​​Key Features and Improvements​​

​​1. Critical Vulnerability Mitigation​​

  • ​​CVE-2024-48721 (CVSS 9.1)​​: Patches buffer overflow vulnerability in IPsec VPN daemon
  • ​​CVE-2024-49005 (CVSS 8.9)​​: Resolves privilege escalation risk through crafted CLI commands
  • ​​CVE-2024-49512 (CVSS 7.5)​​: Fixes XSS vulnerability in FortiView network topology display

​​2. Hardware-Specific Enhancements​​

  • 18% improvement in IPSec VPN throughput (8.9 Gbps → 10.5 Gbps)
  • Reduced memory consumption during deep packet inspection (23% decrease at 95% rule capacity)
  • Enhanced NP6XLite ASIC utilization for SSL/TLS 1.3 bulk encryption

​​3. Protocol Support Updates​​

  • QUIC protocol classification improvements (v2 support)
  • Extended SD-WAN SLA probe compatibility with Azure ExpressRoute
  • BGP route reflector support for IPv6 multicast networks
