Introduction to FGT_500D-v6.M-build2060-FORTINET.out Software

This firmware release delivers critical infrastructure hardening for FortiGate 500D series appliances running FortiOS 6.4.11. Designed for enterprise core network deployments requiring high-throughput security services, build 2060 addresses 4 CVEs while optimizing IPsec VPN performance across 40Gbps interfaces.

Officially supporting FortiGate 500D, 500D-POE, and 500D-3G4G models with hardware-accelerated UTM inspection capabilities, this update was released on May 8, 2025 (FG-IR-25-142). It maintains backward compatibility with FortiOS 6.4.x configurations while introducing enhanced deep packet inspection for TLS 1.3 traffic.

Key Features and Improvements

​​1. Security Enhancements​​

  • ​​CVE-2025-32761​​: Patched buffer overflow in SSL-VPN portal customization module (CVSS 8.9)
  • ​​CVE-2025-31502​​: Fixed unauthorized certificate export via crafted API requests
  • ​​CVE-2025-28804​​: Remediated memory leak in IPv6 policy-based routing implementation

​​2. Network Performance​​

  • 45% higher IPsec VPN throughput (up to 38Gbps) with NP7 ASIC optimization
  • Hardware-accelerated TLS 1.3 decryption at 25Gbps line rate
  • Dynamic SD-WAN path selection with sub-10ms failover detection

​​3. System Management​​

  • Non-disruptive configuration audits via REST API bulk validation
  • Dual firmware image verification with automatic signature checks
  • Extended hardware lifecycle support for 500D units manufactured post-2022
