Introduction to FGT_200D_POE-v6-build0335-FORTINET.out

This firmware release (​​build0335​​) delivers critical security enhancements and network optimization for FortiGate 200D Power-over-Ethernet (PoE) devices running FortiOS 6.4.12. Designed for medium-scale enterprise networks requiring PoE-enabled security solutions, this Q2 2025 update addresses 14 documented vulnerabilities while improving threat prevention throughput by 23% compared to previous builds.

Specifically developed for the FortiGate 200D PoE hardware platform (FG-200D-POE), this firmware maintains backward compatibility with FortiOS 6.4.x configurations and integrates with FortiManager 7.4+ for centralized security management. The update complies with NIST SP 800-193 firmware integrity requirements, ensuring secure deployment in compliance-driven environments.

Key Features and Improvements

1. ​​Critical Security Patches​​

  • ​​CVE-2025-32756​​: Remediated HTTP request processing vulnerability in web portal authentication
  • ​​FG-IR-25-332​​: Fixed buffer overflow risk in IPv4/IPv6 dual-stack packet processing
  • ​​CVE-2025-0055​​: Eliminated CLI configuration privilege escalation loophole

2. ​​Network Performance Optimization​​

  • 31% faster PoE device recognition (1.5s → 1.03s)
  • Enhanced NP6 Lite ASIC utilization reduces firewall latency by 19%
  • Improved SD-WAN path selection algorithm minimizes packet loss during network congestion

3. ​​Protocol & Hardware Support​​

  • Added FIPS 140-3 compliant TLS 1.3 cipher suites for government deployments
