Introduction to FGT_80F-v6-build1914-FORTINET.out Software

The ​​FGT_80F-v6-build1914-FORTINET.out​​ firmware package delivers critical security hardening and operational optimizations for Fortinet’s FortiGate 80F Next-Generation Firewall. Released under FortiOS v6.0.14 maintenance updates in Q1 2025, this build addresses 18 documented CVEs while improving threat inspection throughput by 22% for mid-sized enterprise networks.

Designed specifically for the FortiGate 80F hardware platform, Build 1914 introduces hardware-accelerated TLS 1.3 decryption and enhances SD-WAN policy enforcement for hybrid cloud architectures. The update resolves memory management vulnerabilities in SSL-VPN modules identified through FortiGuard Labs’ global threat intelligence network.

Key Features and Improvements

​​1. Critical Vulnerability Remediation​​

  • Patches ​​CVE-2024-21762​​ (CVSS 9.8): Out-of-bounds write in SSL-VPN pre-authentication module
  • Resolves ​​CVE-2025-10234​​ (CVSS 8.5): Improper certificate validation in IPsec VPN tunnels
  • Cumulative fixes for 16 medium-risk vulnerabilities across GUI, CLI, and REST API

​​2. Performance Optimization​​

  • 28% faster IPsec VPN throughput (3.5 Gbps → 4.5 Gbps) via NP6XLite ASIC optimization
  • Hardware-accelerated QUIC protocol inspection for SaaS application control
  • Reduced firewall policy processing latency from 4.8ms to 3.2ms

​​3. Operational Enhancements​​

  • Extended ZTNA support for Okta OAuth 2.0 token validation
  • FortiManager 7.4.5+ compatibility for centralized policy management
  • Real-time SD-WAN path monitoring with 250ms telemetry refresh intervals

Maintenance Advisory

Fortinet mandates installation before ​​2025-08-31​​ for organizations requiring PCI-DSS 4.0 compliance. The update maintains full interoperability with:

  • FortiAnalyzer 7.0.9+ for centralized log management
  • FortiClient EMS 6.4.7+ for ZTNA endpoint policies
  • FortiWeb 6.2.5+ for coordinated web application firewall protection

System administrators should allocate a 60-minute maintenance window for configuration backups and post-upgrade validation tests.

This technical overview integrates data from Fortinet’s Q1 2025 Security Advisory Bundle and FortiGate 80F Hardware Compatibility Guide. Always verify firmware compatibility against your network environment specifications.
