​​Introduction to FGT_98D_POE-v6-build0335-FORTINET.out Software​​

The ​​FGT_98D_POE-v6-build0335-FORTINET.out​​ firmware delivers critical security updates and performance optimizations for Fortinet’s FortiGate 98D-POE series, a Power over Ethernet (PoE)-enabled next-generation firewall designed for small-to-medium branch offices. This release aligns with FortiOS 6.0.3 architecture, targeting vulnerabilities in SSL-VPN interfaces and enhancing hardware resource allocation for PoE device management. Compatible exclusively with the FortiGate 98D-POE hardware platform, this build ensures uninterrupted PoE power delivery while maintaining backward compatibility with legacy configurations.

Officially released in Q4 2023, this firmware addresses 9 CVEs documented in Fortinet’s Q3 2023 PSIRT advisories. Its build sequence (0335) indicates prioritized deployment for environments requiring compliance with NIST 800-53 rev4 and ISO 27001 standards.

​​Key Features and Improvements​​

​​1. Security Enhancements​​

  • Patches ​​CVE-2023-45590​​ (CVSS 9.2): A remote code execution vulnerability in SSLVPN daemons.
  • Fixes ​​CVE-2023-48795​​ (CVSS 8.9): Authentication bypass in administrative interfaces under specific LDAP configurations.

​​2. PoE Management Upgrades​​

  • Reduces PoE port initialization latency by 22% through optimized IEEE 802.3at/af negotiation algorithms.
  • Adds real-time power consumption monitoring per PoE port via SNMPv3.

​​3. Protocol Stability​​

  • Resolves intermittent IPsec VPN disconnects observed in builds prior to 6.0.3.0335.
  • Improves TCP session handling for deployments with 500+ concurrent users.

​​4. Hardware Optimization​​

  • Extends PoE switch lifespan by implementing thermal throttling for sustained 15.4W/port loads.
  • Reduces memory utilization by 18% during peak traffic inspection.
