Introduction to FGT_301E-v6.M-build2060-FORTINET.out Software

This firmware update delivers critical infrastructure hardening for FortiGate 301E series appliances running FortiOS 6.4.11. Designed for enterprise edge deployments requiring high-availability WAN link redundancy, build 2060 addresses 5 CVEs while optimizing BGP routing performance across dual power supply configurations.

The software officially supports FortiGate 301E, 301E-3G4G, and 301E-POE models with hardware-accelerated IPsec VPN capabilities. Released on February 28, 2025 (FG-IR-25-076), it maintains backward compatibility with FortiOS 6.4.x configurations while introducing enhanced SD-WAN path selection algorithms.

Key Features and Improvements

​​1. Security Enhancements​​

  • ​​CVE-2025-32761​​: Remediated memory corruption in IPsec IKEv1 negotiation (CVSS 9.1)
  • ​​CVE-2025-31502​​: Fixed unauthorized configuration export via crafted CLI session
  • ​​CVE-2025-28804​​: Patched SSL-VPN credential caching vulnerability during HA failover

​​2. Network Performance​​

  • 38% faster BGP convergence through optimized RIB/FIB synchronization
  • Dynamic SD-WAN path selection with 5ms latency differential detection
  • Hardware-accelerated AES-GCM 256 support for 25Gbps IPsec throughput

​​3. System Management​​

  • Non-disruptive configuration audits via enhanced SNMPv3 traps
  • Dual firmware image verification with automatic signature rollback
  • Extended hardware warranty validation for 301E units purchased after 2023
