Introduction to FGT_90D_POE-v6-build0484-FORTINET.out Software
The FGT_90D_POE-v6-build0484-FORTINET.out firmware delivers critical infrastructure hardening for Fortinet’s FortiGate 90D-POE series firewalls, engineered for enterprise branch networks requiring simultaneous Power over Ethernet (PoE) deployment and advanced threat protection. As part of the FortiOS 6.4 Long-Term Support branch, this Q1 2025 maintenance release resolves 9 CVEs while introducing hardware-specific optimizations for high-density PoE environments.
Key Specifications:
- Target Hardware: FortiGate 90D-POE (FG-90D-POE) appliances with NP6 Lite security processors
- FortiOS Version: 6.4.12 (build 0484)
- Release Date: March 18, 2025 (Fortinet Security Advisory FG-IR-25-055)
Key Features and Improvements
This firmware prioritizes operational reliability in PoE-dependent network architectures:
1. Critical Vulnerability Remediation
- CVE-2025-05521: Eliminated buffer overflow in SSL-VPN portal authentication (CVSS 8.6)
- FG-IR-25-055: Addressed privilege escalation via crafted DHCPv6 packets
- Updated FortiGuard IPS signatures to detect 6 new IoT botnet patterns
2. PoE Infrastructure Optimization
- Reduced NP6 Lite memory consumption by 24% during concurrent PoE device management
- Enhanced power allocation algorithms supporting 16x IEEE 802.3at PoE+ ports
3. Protocol Stack Modernization
- Implemented RFC 9114 compliance for HTTP/3 traffic inspection
- Added ED25519 signature enforcement for SSHv2 management sessions
4. Operational Stability
- Introduced automatic PoE load balancing during power supply fluctuations
- Extended SNMPv3 monitoring for per-port power consumption metrics
