Introduction to FGT_140E_POE-v7.0.4-build0301-FORTINET.out Software

The ​​FGT_140E_POE-v7.0.4-build0301-FORTINET.out​​ firmware package delivers critical updates for Fortinet’s FortiGate 140E Power over Ethernet (PoE) series firewalls, designed for mid-sized enterprise networks requiring integrated security and power delivery capabilities. Released under FortiOS 7.0.4 maintenance updates in Q1 2025, this build targets vulnerabilities identified in legacy SD-WAN and VPN services while enhancing energy efficiency for PoE device management.

Compatible exclusively with the FortiGate 140E PoE hardware platform, this firmware (version 7.0.4 build 0301) resolves 14 documented CVEs, including 3 critical risks affecting SSL-VPN and captive portal services. Network administrators managing campus networks or distributed IoT deployments will benefit from its improved integration with FortiSwitch PoE controllers and dynamic power allocation algorithms.
