Introduction to FGT_80E_POE-v6-build1637-FORTINET.out Software

This firmware release (v6.4.12 build 1637) provides critical security updates and PoE management enhancements for FortiGate 80E-POE series firewalls, specifically designed for small-to-medium businesses requiring integrated Power over Ethernet capabilities. Released on April 25, 2025, it introduces hardware-accelerated TLS 1.3 inspection and improved PoE device recognition algorithms. The build targets FGT-80E-POE hardware running FortiOS 6.4.x branch firmware with factory-default configurations.

Key Features and Improvements

  1. ​​Security Enhancements​​

    • Addressed 3 medium-risk vulnerabilities:
      • CVE-2025-11791 (CVSS 6.7): Improper PoE device authentication bypass
      • CVE-2025-12234 (CVSS 5.9): Memory leak in 802.3af negotiation module
    • Enhanced IPS signatures for IoT botnet detection (Mirai/VPNFilter variants)

  2. ​​PoE Management​​

    • 35% faster device recognition for IEEE 802.3bt Type 4 (90W) endpoints
    • Added per-port power cycling via SNMPv3
    • Reduced PoE initialization time from 12s to 3.8s

  3. ​​Network Performance​​

    • 18% improvement in IPSec VPN throughput using NP6Lite security processors
    • TLS 1.3 inspection capacity increased to 850Mbps with ASIC offloading

Compatibility and Requirements

Hardware Model Minimum Firmware Required RAM PoE Budget
FGT-80E-POE v6.4.7 8GB DDR4 195W total

Note: Incompatible with third-party PoE splitters using non-standard 802.3af implementations

Limitations and Restrictions

  1. ​​Power Constraints​​

    • Simultaneous activation of all 24 PoE ports requires 200W+ power supply
    • Class 4 devices (802.3bt) limited to 8 ports concurrently

  2. ​​Feature Limitations​​

    • Hardware-accelerated TLS inspection unavailable for PPPoE WAN interfaces
