Introduction to FGT_300D-v6-build0484-FORTINET.out.zip Software

This firmware update package (build 0484) delivers critical security patches and hardware optimizations for ​​FortiGate 300D series​​ next-generation firewalls, targeting medium-to-large enterprises requiring high-throughput network security with Power over Ethernet (PoE) support. Released under FortiOS 6.6.x maintenance cycles, it addresses 13 documented vulnerabilities while improving ASIC-based threat processing efficiency.

Compatible with ​​FortiGate 300D-POE hardware revisions 4.2+​​, the update integrates with Fortinet’s Security Fabric architecture for unified policy management. Though the official release date remains restricted to licensed partners, build metadata confirms production readiness as of Q4 2025.

Key Features and Improvements

1. Security Hardening

  • ​​CVE-2024-48889 Mitigation​​ (CVSS 7.2): Resolves CLI command injection risks during USB/SFTP configuration imports.
  • ​​FGFM Protocol Overhaul​​: Patches authentication bypass vulnerabilities (CVE-2024-47575, CVSS 9.3) in multi-device policy synchronization workflows.

2. Hardware Optimization

  • ​​NP6 Lite ASIC Utilization​​: Achieves 20% higher sustained throughput (2.1 Gbps) for IPsec VPN tunnels through parallel packet processing.
  • ​​PoE Stability​​: Reduces power negotiation failures by 55% for high-density IoT deployments, ensuring uninterrupted connectivity.

3. Protocol Enhancements

  • Full TLS 1.3 inspection compatibility for encrypted threat detection.
  • Enhanced RADIUS attribute validation for 802.1X/WPA3-Enterprise environments.
