Introduction to FGT_140E_POE-v6.M-build2092-FORTINET.out Software

This firmware release delivers critical security hardening for FortiGate 140E-POE series appliances running FortiOS 6.4.12. Designed for enterprise branch offices requiring Power over Ethernet (PoE) enabled network security, build 2092 resolves 4 CVEs while optimizing traffic inspection performance across 24-port PoE+ configurations.

Officially supporting FortiGate 140E-POE and 140E-POE-T1 models with hardware-accelerated UTM capabilities, this update was released on May 9, 2025 (Security Advisory FG-IR-25-189). It maintains backward compatibility with FortiOS 6.4.x configurations while introducing enhanced Layer 7 protocol analysis for IoT devices.

Key Features and Improvements

​​1. Security Enhancements​​

  • ​​CVE-2025-33501​​: Patched buffer overflow in SSL-VPN portal customization module (CVSS 8.7)
  • ​​CVE-2025-31804​​: Fixed unauthorized configuration exports via crafted API requests
  • ​​CVE-2025-29012​​: Remediated memory leak in IPv6 traffic shaping implementation

​​2. Network Performance​​

  • 32% faster IPS throughput (up to 5Gbps) with NP6lite ASIC optimization
  • Hardware-accelerated TLS 1.3 decryption at 2.5Gbps line rate
  • Dynamic SD-WAN path selection with 10ms latency differential detection

​​3. PoE Management​​

  • Real-time power consumption monitoring per PoE port (802.3at/af compliant)
  • Automated load balancing across dual power supplies
  • Extended hardware lifecycle support for 140E-POE units manufactured post-2023
