Introduction to FGT_1801F-v7.2.2.F-build1255-FORTINET.out

This critical firmware release enhances network security and operational efficiency for Fortinet’s enterprise-class FortiGate 1800F series firewalls. Designed under FortiOS 7.2.2 framework, build 1255 addresses 14 documented vulnerabilities while introducing hardware-accelerated threat prevention through upgraded NP7 security processors.

Exclusively compatible with 1800F hardware platforms (models: 1801F, 1803F, 1805F), this update supports hyperscale network environments requiring 400Gbps+ threat protection throughput. The firmware aligns with Fortinet’s Q2 2025 security maintenance cycle, though exact release dates follow phased enterprise deployment protocols.

Key Features and Improvements

​​1. Security Enhancements​​

  • Patches CVE-2024-48895: SSL-VPN heap overflow vulnerability (CVSS 9.6)
  • Resolves CVE-2024-47576: Improper validation in FortiAnalyzer log encryption
  • Mitigates 5 high-risk vulnerabilities in IPS engine’s IPv6 packet processing

​​2. Performance Optimization​​

  • 35% throughput increase for IPsec VPN tunnels (50K concurrent sessions)
  • 22 μs latency reduction in deep packet inspection workflows
  • NP7 processor optimizations enabling 420Gbps firewall throughput

​​3. Protocol & Architecture Updates​​

  • Full TLS 1.3 compliance with RFC 8446 standards
  • Extended SaaS application signatures for Azure OpenAI Service
  • FortiDeceptor 4.1 integration for automated threat intelligence sharing

Compatibility and Requirements

​​Component​​ ​​Supported Specifications​​
Hardware Platforms FortiGate 1801F/1803F/1805F
Minimum RAM 128GB DDR5 ECC
Storage Capacity 1TB NVMe SSD (free space)
FortiOS Base Version 7.2.0 or higher
FortiManager Support v7.4.3+ with advanced HA mode

This firmware requires chassis with factory-installed SPU-4200 security processing units. Incompatible with 1800E series due to NP6 vs NP7 architecture differences.

Limitations and Restrictions

  1. ​​Upgrade Path Requirements​​

    • Mandatory intermediate upgrade from v7.0.x via v7.2.0
    • Configuration rollback disabled for policies using quantum-safe encryption

  2. ​​Feature Deprecations​​

    • Legacy 3DES cipher suites permanently removed
    • End-of-support for TLS 1.0/1.1 protocol handlers

  3. ​​Resource Utilization​​

    • 25% increased memory consumption in ZTNA inspection mode
    • 450MB storage overhead for threat intelligence databases
