Introduction to FGT_60F-v6-build6665-FORTINET.out.zip

The ​​FGT_60F-v6-build6665-FORTINET.out.zip​​ firmware package delivers critical security updates and operational optimizations for FortiGate 60F series next-generation firewalls. As part of FortiOS 6.4.18, this build addresses multiple vulnerabilities while maintaining compliance for small-to-medium businesses (SMBs) requiring extended hardware lifecycles. Though Fortinet officially transitions support to newer FortiOS 7.x branches, build6665 remains essential for organizations prioritizing stability in legacy environments.

This firmware exclusively supports ​​FortiGate 60F appliances​​, including the 60F, 60F-POE, and 60F-3G4G models. Designed for networks with 11-25 users, it balances 10 Gbps firewall throughput and 700 Mbps threat protection capacity, making it ideal for retail branches, clinics, and remote offices.


Key Features and Improvements

​1. Critical Vulnerability Remediation​

  • ​CVE-2024-55591 Mitigation​​: Eliminates authentication bypass risks in management interfaces that allowed unauthorized super-admin access.
  • ​CVE-2025-24472 Resolution​​: Addresses privilege escalation vulnerabilities in Security Fabric trust hierarchies.

​2. Network Performance Enhancements​

  • ​SD-WAN Optimization​​: Reduces packet loss by 33% in multi-WAN failover scenarios through improved path selection algorithms.
  • ​SSL Inspection Efficiency​​: Boosts TLS 1.3 inspection throughput by 18% via NP6lite ASIC optimizations.

​3. Protocol & Compliance Updates​

  • ​Zero Trust Network Access (ZTNA)​​: Enhances certificate-based authentication for hybrid workforce security.
  • ​BGP Route Stability​​: Fixes AS_PATH attribute corruption in dual-stack IPv4/IPv6 environments.
