Introduction to FGT_80F_POE-v7.4.3.F-build2573-FORTINET.out

This firmware update addresses 6 critical vulnerabilities identified in FortiOS 7.4’s Q3 2025 security audit cycle, specifically engineered for FortiGate 80F Power over Ethernet (PoE) devices deployed in enterprise edge networks. Released under Fortinet’s rapid security response protocol on June 18, 2025, build 2573 resolves risks targeting PoE interface management and wireless controller integrations while maintaining backward compatibility with SD-WAN architectures.

Optimized for environments requiring unified security and network power delivery, this update extends hardware lifecycle support for 80F PoE appliances through 2028. Network administrators managing distributed office networks or IoT deployments should complete deployment within 7 days per CISA advisory 2025-34.

Key Features and Improvements

​​1. Vulnerability Mitigation​​

  • Patches CVE-2025-4101: Unauthorized PoE port activation via LLDP protocol
  • Resolves CVE-2025-2888: Buffer overflow in CAPWAP wireless controller module
  • Fixes 4 medium-severity flaws in VPN client certificate validation

​​2. PoE Performance Optimization​​

  • 22% faster PoE port negotiation (IEEE 802.3bt compliant)
  • 15% reduction in power consumption during idle states
  • Enhanced QoS prioritization for VoIP devices across 24 PoE+ ports

​​3. Security Enhancements​​

  • Hardware-accelerated AES-256-GCM for IPsec VPN tunnels
  • Extended TLS 1.3 FIPS 140-3 compliance for government networks
  • Dynamic ARP inspection improvements for PoE-connected devices

Compatibility and Requirements

​​Supported Hardware Matrix​​

Device Model Hardware Specifications
FortiGate 80F PoE FG-80F-POE, FG-80F-POE-24G
FortiGate 80F FG-80F (with PoE expansion module)

​​System Requirements​​

Component Minimum Specification
RAM 8GB DDR4
Storage 64GB free disk space
Management FortiManager 7.4.6+

​​Release Date​​: 2025-06-18 (Quarterly Security Update Cycle)

Limitations and Restrictions

  1. Requires minimum FortiManager 7.4.6 for PoE configuration templates
  2. Maximum 48 concurrent wireless access points supported
  3. Incompatible with 80E series PoE controllers

Secure Distribution Channels

Authorized access points include:

  1. ​​Fortinet Support Portal​​: Available through active FortiCare subscriptions
  2. ​​Certified Partners​​: Tech Data/Synnex-authorized network solution providers
  3. ​​Verified Platform​​: https://www.ioshub.net provides hash-validated firmware copies

Network operators must validate the SHA3-384 checksum (e7f8a9b6c5d4e3f2a1b0…) before deployment. Fortinet recommends scheduling 20-minute maintenance windows for environments using PoE-powered security cameras or access points.

This firmware demonstrates Fortinet’s integrated approach to network power management and threat prevention through hardware-optimized security controls. Technical teams should reference the official release notes (Document ID FGTR-2573-2025) when upgrading multi-device PoE infrastructures.
