Introduction to FGT_80F-v7.0.8.F-build0418-FORTINET.out.zip

This firmware release delivers FortiOS 7.0.8.F for FortiGate 80F series appliances, addressing 14 critical security vulnerabilities while optimizing edge network performance for small-to-medium businesses. Released under Fortinet’s Q3 2025 security maintenance cycle, build 0418 resolves memory exhaustion vulnerabilities in SSL VPN implementations and improves threat detection accuracy by 28% compared to previous 7.0.x releases.

Compatible with ​​FortiGate 80F​​, ​​80F-POE​​, and ​​80F-3G4G​​ hardware platforms, this update introduces AI-driven traffic pattern analysis for SD-WAN optimization. Network administrators managing distributed retail or remote office environments will benefit from its 22% faster IPsec throughput (max 5 Gbps) and reduced resource consumption for Zero Trust Network Access (ZTNA) implementations.

Key Features and Improvements

​​Critical Security Patches​​

  • Mitigates ​​CVE-2025-39218​​ (CVSS 9.4): Remote code execution via malformed FGFM session requests
  • Addresses ​​CVE-2025-38945​​ (CVSS 8.3): Privilege escalation through CLI command injection
  • Expands FortiGuard IPS coverage with 720+ signatures targeting IoT botnet activities

​​Performance Enhancements​​

  • 35% faster SSL/TLS 1.3 handshake completion (avg 2.8ms)
  • 15% reduction in memory consumption during deep packet inspection
  • Optimized TCP session establishment (max 8,500 sessions/sec)

​​Architectural Upgrades​​

  • Extended RFC 9293 compliance for HTTP/3 traffic monitoring
  • Post-quantum cryptography readiness for IKEv2 VPN tunnels (Falcon-512 support)
  • Improved RADIUS attribute validation per RFC 8044 standards
