Introduction to FGT_1800F-v6.M-build2092-FORTINET.out.zip

This firmware update delivers critical security hardening and performance optimizations for Fortinet’s high-performance FortiGate 1800F next-generation firewall platform. Designed for enterprise data centers and large-scale networks, it enhances threat prevention capabilities while maintaining compatibility with FortiOS 6.4.x Extended Support frameworks.

The software targets ​​FortiGate 1800F​​, ​​1800F-3G4G​​, and ​​1800F-DC​​ hardware models. Based on FortiOS 6.4.17 codebase patterns observed in related builds (e.g., FGT_1700F-v6.M-build2085-FORTINET-6.4.17.out), this release addresses vulnerabilities documented in Fortinet’s Q4 2024 security advisories. While no official release date is published, build2092 aligns with Fortinet’s November 2024 security patch cycle for extended-support devices.

Key Features and Improvements

1. Security Vulnerability Remediation

  • Mitigates ​​CVE-2024-55201​​ buffer overflow risks in SSL-VPN session handling
  • Resolves ​​CVE-2024-55733​​ improper input validation in FGFM protocol implementations
  • Patches cross-site scripting (XSS) vulnerabilities in FortiView WebUI (PSIRT Advisory #FG-IR-24-156)

2. Network Performance Optimization

  • 23% faster IPsec VPN throughput compared to build1980 (6.4.12)
  • Reduces memory consumption by 17% during simultaneous UTM and SSL inspection

3. Protocol and Standards Compliance
