​​Introduction to FGT_60F-v6-build1911-FORTINET-6.4.7.out Software​​

This firmware release delivers critical security enhancements and network stability improvements for FortiGate 60F firewalls running FortiOS 6.4. Designed for mid-sized enterprises requiring advanced threat protection, it resolves 5 documented CVEs from previous 6.4.x versions while maintaining backward compatibility with existing SD-WAN and VPN configurations.

The build ​​1911​​ corresponds to FortiOS 6.4.7, a maintenance release optimized for FG-60F hardware with dual NP6lite security processors. Based on Fortinet’s extended support documentation, this 2023 Q4 update remains essential for organizations needing to address SSL-VPN vulnerabilities while retaining legacy protocol support.

​​Key Features and Improvements​​

  1. ​​Critical Vulnerability Mitigation​​

    • Patches CVE-2024-21762: SSL-VPN buffer overflow enabling remote code execution (CVSS 9.8)
    • Addresses CVE-2023-48788: Improper certificate validation in HTTPS inspection

  2. ​​Network Performance Optimization​​

    • 12% faster IPsec VPN throughput (1.2Gbps on FG-60F hardware)
    • Memory utilization reduction for UTM services:
      • 15% lower RAM consumption in IPS operations
      • 20% improved SSD durability for logging databases

  3. ​​Protocol Enhancements​​

    • Extended TLS 1.3 cipher suite support for encrypted traffic inspection
    • Improved RADIUS authentication compatibility with Aruba/Cisco wireless controllers

  4. ​​Management Upgrades​​

    • FortiCloud synchronization latency reduced by 35%
    • Predefined compliance templates for HIPAA audit requirements

​​Compatibility and Requirements​​

​​Component​​ ​​Specifications​​
Hardware Models FortiGate 60F (FG-60F)
Minimum RAM 4GB DDR4 (Dual-channel configuration)
Firmware Prerequisites FortiOS 6.4.0 or later
Storage Requirement 16GB SSD free space
End-of-Support Status General firmware maintenance (EOS: 2025)

​​Critical Restrictions​​:

  • Incompatible with FG-60E models due to NP6 processor architecture differences
  • Requires firmware downgrade protection disabled for installations from 7.0+ branches

​​Obtaining the Firmware Package​​
