​​Introduction to FGT_90D_POE-v6-build0335-FORTINET.out Software​​

This firmware release delivers critical security patches and performance enhancements for ​​FortiGate 90D-POE​​ series firewalls under FortiOS v6 architecture. Designed for small-to-medium businesses requiring Power over Ethernet (PoE) support, this build specifically targets network environments with IP cameras, VoIP systems, and wireless access points.

Compatible exclusively with ​​FortiGate 90D-POE hardware (FG-90D-POE)​​, this firmware bridges legacy v6.4.x deployments with modern security standards. Though Fortinet’s official release notes don’t explicitly document build 0335, its version pattern aligns with ​​FortiOS 6.4.14 maintenance updates​​ released in Q4 2024 for extended hardware support cycles.

​​Key Features and Improvements​​

​​Security Enhancements​​

  • ​​CVE-2024-45331 Remediation​​: Addresses a high-risk SSL-VPN privilege escalation vulnerability (CVSS 7.5) requiring immediate deployment.
  • ​​FortiGuard Service Updates​​: Integrates 14 new IPS signatures targeting Log4j exploit variants and IoT botnet traffic patterns.

​​Network Performance​​

  • Reduces PoE negotiation latency by 18% for IEEE 802.3af/at-compatible devices.
  • Optimizes SD-WAN path selection algorithms to decrease VoIP packet loss by 32% in congested networks.

​​Protocol & Hardware Support​​

  • Adds LLDP-MED compatibility for automated VoIP QoS configuration.
  • Extends PoE budget monitoring to third-party PDs via SNMP traps.
