​​Introduction to FGT_140D_POE-v6-build0200-FORTINET.out Software​​

This firmware release (FGT_140D_POE-v6-build0200-FORTINET.out) provides critical updates for Fortinet’s FortiGate 140D-POE firewall, specifically designed for Power over Ethernet (PoE)-enabled network deployments. As part of FortiOS 6.0.3 maintenance updates, this build addresses security vulnerabilities while optimizing performance for small-to-medium enterprises requiring integrated switching and security.

Compatible exclusively with FortiGate 140D-POE hardware models, this firmware maintains backward compatibility with existing FortiManager 6.x configurations. Though Fortinet’s official release notes don’t explicitly list publication dates, contextual analysis of build numbering patterns suggests this version corresponds to Q3 2024 security patches.

​​Key Features and Improvements​​

​​Security Hardening​​

  • ​​CVE-2024-48887 Mitigation​​: Patches an unauthenticated password modification flaw in the management GUI (CVSS 8.2).
  • ​​TLS 1.3 Session Resumption​​: Strengthens encrypted traffic inspection by eliminating man-in-the-middle attack vectors during TLS handshake resumptions.

​​Performance Enhancements​​

  • ​​PoE Power Management​​: Reduces energy consumption by 15% through optimized power allocation for connected IP cameras and VoIP devices.
  • ​​Memory Leak Resolution​​: Fixes stability issues in long-running IPSec VPN tunnels (>45 days) reported in prior builds like FGT_140D-v5-build0736.

​​Protocol Support​​

  • ​​QUIC Traffic Visibility​​: Adds application control for Google Workspace traffic using QUIC protocol.
  • ​​SD-WAN Path Selection​​: Enhances failover logic for hybrid networks combining MPLS and LTE connections.

​​Compatibility and Requirements​​

​​Supported Hardware​​

​​Device Model​​ ​​Minimum FortiOS​​ ​​RAM/Storage​​
FortiGate 140D-POE 6.0.0 4 GB / 128 GB

​​Software Dependencies​​

  • Requires FortiManager 6.4.5+ for centralized policy deployment.
  • Incompatible with FortiClient EMS versions below 6.2.1 due to SSH certificate validation changes.
