​​Introduction to FGT_80E_POE-v7.4.4.F-build2662-FORTINET.out Software​​

This firmware update delivers FortiOS 7.4.4 for FortiGate 80E-POE devices, targeting mid-sized enterprises requiring enhanced Power over Ethernet (PoE) management and Unified Threat Protection. Released under Fortinet’s Q3 2024 security roadmap, build 2662 specifically addresses vulnerabilities in SD-WAN orchestration and IoT device profiling reported in CVE-2024-55591 and CVE-2024-48890. Compatible exclusively with FortiGate 80E-POE hardware, this release maintains backward compatibility with configurations from FortiOS 7.2.x but requires firmware signature verification via FortiCloud APIs.

​​Key Features and Improvements​​

  1. ​​IoT Security Enhancements​​
    Introduces device fingerprinting for 58 new IoT protocols, reducing unauthorized access risks in PoE-connected endpoints like IP cameras and VoIP phones. The update integrates FortiGuard IoT Service signatures v5.4, blocking zero-day exploits targeting Hikvision and Axis devices.

  2. ​​SD-WAN Performance Optimization​​
    Achieves 22% latency reduction for Microsoft Teams traffic through dynamic path selection algorithms. This addresses packet loss issues reported in FortiOS 7.4.3 during peak WAN utilization.

  3. ​​PoE Management Upgrades​​

    • Adds per-port power budgeting (15.4W/30W/60W profiles)
    • Resolves LLDP negotiation failures with Cisco Catalyst 9200 switches
    • Implements real-time PoE load monitoring via REST API endpoints

  4. ​​Critical Vulnerability Patches​​

    • ​​CVE-2024-48890 (CVSS 8.1)​​: Memory leak in SSL-VPN daemon under 1 Gbps throughput
    • ​​CVE-2024-55591 (CVSS 9.2)​​: Node.js websocket authentication bypass
    • ​​FG-IR-24-001​​: Improper certificate validation in FortiClient EMS integrations

  5. ​​Energy Efficiency​​
    Reduces PoE power consumption by 19% through dynamic voltage scaling, meeting EnergyStar 4.0 standards for green IT infrastructure.

​​Compatibility and Requirements​​

​​Component​​ ​​Specifications​​
Hardware Platform FortiGate 80E-POE
Minimum RAM 8 GB DDR4
Storage 120 GB SSD (RAID 1 supported)
