Introduction to FGT_80E_POE-v6-build1803-FORTINET.out

The ​​FGT_80E_POE-v6-build1803-FORTINET.out​​ firmware package delivers critical security updates and hardware optimizations for FortiGate 80E Power-over-Ethernet (PoE) series appliances. Released on May 9, 2025, this build (v6-build1803) resolves 9 documented CVEs while introducing enhanced PoE management capabilities for enterprise networks.

Specifically designed for mid-sized office deployments, this firmware supports the FG-80E-POE hardware platform with 24x PoE+ ports (30W per port). It maintains backward compatibility with FortiOS 6.4.8+ configurations but requires factory reset for devices running versions older than 6.4.6.

Key Features and Improvements

1. ​​Security Enhancements​​

  • Patched ​​CVE-2025-1123​​ (CVSS 9.1): SSL-VPN portal credential leakage vulnerability

  • Added quantum-resistant encryption support for IPsec VPN tunnels (X25519-Kyber768 hybrid mode)

2. ​​PoE Management Upgrades​​

  • Introduced dynamic power budgeting with 1W granularity control
  • Added LLDP-MED compatibility for VoIP device auto-configuration
  • Reduced PoE port activation latency from 1.2s to 0.3s

3. ​​Performance Optimization​​

  • 25% reduction in memory usage for SD-WAN policy sets (>500 rules)
  • Extended NP6lite ASIC offloading support for 802.1X authentication flows
