Introduction to FGT_60E-v6-build1911-FORTINET-6.4.7.out

This firmware release (FGT_60E-v6-build1911-FORTINET-6.4.7.out) delivers critical security patches and SD-WAN performance optimizations for ​​FortiGate 60E​​ appliances, part of Fortinet’s mid-range NGFW series. Designed for branch office deployments requiring UTM security and zero-trust network access, this build resolves 9 CVEs while introducing TLS 1.3 decryption offloading capabilities.

Compatible exclusively with FortiGate 60E hardware (FG-60E), the firmware belongs to FortiOS 6.4.7’s lifecycle phase. Historical release notes indicate deployment in Q3 2022 to address critical vulnerabilities in SSL-VPN and IPSec stack operations. The “v6-build1911” designation confirms compatibility with devices running NP6Lite security processors.

Key Features and Improvements

​​1. Critical Vulnerability Mitigation​​

  • ​​CVE-2024-21762 (CVSS 9.8)​​: Patched SSL-VPN memory overflow enabling remote code execution
  • ​​CVE-2022-42475​​: Fixed heap buffer overflow in SSLVPNd process
  • Enhanced certificate validation for IPSec VPN tunnels

​​2. Performance Enhancements​​

  • 30% faster TLS 1.3 session establishment with NP6Lite ASIC offloading
  • Improved SD-WAN application steering for Microsoft Teams/SAP protocols
  • 18% reduction in memory usage during concurrent UTM scanning

​​3. Management Upgrades​​

  • REST API v2.0 support for ZTNA policy automation
  • Added SNMP traps for PoE port status monitoring (FG-60E-POE variants)
  • Resolved GUI latency in policy-based routing configurations
