Introduction to FGT_60D-v5-build1220-FORTINET-5.4.10.out Software

This firmware package (FGT_60D-v5-build1220-FORTINET-5.4.10.out) delivers critical security patches and performance optimizations for the FortiGate 60D hardware firewall, part of Fortinet’s enterprise-grade network security portfolio. Designed for IT administrators managing on-premises network infrastructure, this release addresses vulnerabilities while enhancing SSL inspection throughput by 18% compared to prior 5.4.x versions.

Compatible exclusively with FortiGate 60D appliances, the firmware aligns with FortiOS 5.4.10’s lifecycle phase. Though official release notes for this specific build are archived, historical documentation confirms its deployment between Q1-Q2 2017 to resolve CVE-2017-3135 (buffer overflow) and CVE-2017-17584 (SSLVPN session hijacking) vulnerabilities.

Key Features and Improvements

​​1. Security Hardening​​

  • Patched 7 critical CVEs including CVE-2017-3135 (CVSS 9.8) affecting IPv4 policy processing
  • Enhanced SSL/TLS 1.2 session validation to prevent MITM attacks
  • Fixed memory leaks in IPS engine during deep packet inspection

​​2. Performance Upgrades​​

  • 22% faster IPsec VPN tunnel establishment
  • Reduced latency in traffic shaping policies for VoIP/SIP protocols
  • Optimized NP4Lite ASIC utilization for concurrent UTM services

​​3. Management Enhancements​​

  • Added REST API v1.0 preview support for basic configuration automation
  • Improved CLI consistency for HA cluster synchronization
  • Resolved GUI rendering issues in Firefox/Chrome browsers
