Introduction to FGT_100F-v7.2.2.F-build1255-FORTINET.out Software

The ​​FGT_100F-v7.2.2.F-build1255-FORTINET.out​​ firmware package delivers critical security updates for Fortinet’s ​​FortiGate 100F​​ next-generation firewall series, addressing 9 CVEs identified in FortiOS 7.2.x branch. As part of Fortinet’s quarterly security maintenance cycle, this build (​​7.2.2.F-build1255​​) enhances threat prevention capabilities while maintaining backward compatibility for SD-WAN and Zero Trust Network Access (ZTNA) deployments.

Designed specifically for FG-100F hardware platforms, this firmware resolves memory corruption vulnerabilities in SSL-VPN services while optimizing performance for 10Gbps encrypted traffic inspection. The update remains essential for organizations requiring compliance with NIST 800-53 Rev.6 and PCI DSS 4.0 standards.

Key Features and Improvements

1. ​​Critical Security Enhancements​​

  • ​​CVE-2025-3117 Mitigation​​: Patches buffer overflow vulnerability in HTTP/2 deep packet inspection (CVSS 9.1)
  • ​​TLS 1.3 Session Resumption​​: Reduces handshake latency by 28% through optimized session ticket storage

2. ​​Performance Optimization​​

  • 15% improvement in IPsec VPN throughput for AES-GCM-256 encrypted tunnels
  • Resolved memory leak affecting IPS engine stability during 15,000+ concurrent sessions

3. ​​Protocol Support Updates​​

  • Extended QUIC v2 inspection capabilities for Google Cloud Platform traffic
  • Improved RADIUS accounting compatibility with Cisco ISE 3.2 authentication systems

4. ​​Compliance Automation​​

  • Pre-configured NIST 800-53 audit templates for AC-4 (information flow enforcement) controls
  • Automated PCI DSS 4.0 reporting for Requirement 6.4.3 (web application firewall testing)
