Introduction to FGT_80E_POE-v6-build0335-FORTINET.out Software

This firmware update delivers critical security patches and operational improvements for mid-range FortiGate 80E-POE appliances with Power over Ethernet (PoE) capabilities. Designed for branch offices requiring 1-5 Gbps firewall throughput, build 0335 resolves 9 CVEs identified in FortiOS 6.0 releases while optimizing energy efficiency for PoE device management.

The software exclusively supports FortiGate 80E-POE models manufactured after Q3 2024, featuring hardware revisions 3A+ (serial numbers FG8EP3Axxxxx+). Released via Fortinet’s security response channel on May 10, 2025, this emergency update addresses active exploitation attempts targeting previous builds. A mandatory SHA-384 checksum validation is enforced during installation to prevent firmware tampering.
