The ​​FGT_800D-v6-build1828-FORTINET.out​​ firmware package delivers critical security patches and performance optimizations for Fortinet’s FortiGate 800D series, a high-availability firewall designed for enterprise data centers and large-scale networks. This release addresses 11 documented vulnerabilities while enhancing operational stability for environments requiring high-throughput threat prevention.

​​Compatible Devices​​:

  • FortiGate 800D appliances running FortiOS 6.4.x
  • Validated variants: FG-800D with dual power supply configurations

​​Version Details​​:

  • Build version: ​​v6-build1828​​ (released Q3 2024 per Fortinet’s firmware lifecycle documentation)
  • Base OS compatibility: FortiOS 6.4.5 with backward configuration support for 6.2.16+

​​Key Features and Improvements​​

This firmware resolves critical vulnerabilities observed in recent network attacks while introducing enterprise-grade operational refinements:

  1. ​​Critical Security Updates​​:

    • Patches ​​CVE-2024-23125​​ (CVSS 9.1): SSL-VPN portal buffer overflow vulnerability
    • Fixes ​​CVE-2024-24580​​ (CVSS 8.9): HTTP/2 session hijacking exploit

  2. ​​Performance Enhancements​​:

    • 20% throughput increase for IPsec VPN tunnels (validated at 60 Gbps on 800D hardware)
    • 25% reduction in memory consumption during deep packet inspection workflows

  3. ​​Protocol Modernization​​:

    • TLS 1.3 FIPS 140-3 compliance for government/military deployments
    • Enhanced BGP route processing for networks with 30,000+ routing entries

  4. ​​Management System Upgrades​​:

    • FortiManager 7.4.5+ synchronization stability improvements
    • REST API response acceleration (35% faster than build 1700)
