Introduction to FGT_240D_POE-v6-build0365-FORTINET.out

The ​​FGT_240D_POE-v6-build0365-FORTINET.out​​ firmware package delivers critical security updates and operational enhancements for Fortinet’s enterprise-class FortiGate 240D Power over Ethernet (PoE) series next-generation firewalls. Released under ​​FortiOS 6.4.15​​, this build addresses memory management vulnerabilities while optimizing encrypted traffic analysis for medium-scale networks.

​Primary Objectives​​:

  • Mitigate heap overflow risks in SSL-VPN authentication workflows
  • Enhance IPSec VPN throughput for remote workforce connectivity
  • Strengthen IoT device identification capabilities

​Compatible Devices​​:

  • FortiGate 240D-POE (FG-240D-POE)
  • FortiGate 240D-POE-T1 (Telecom variant with T1/E1 interfaces)

Key Features and Improvements

1. ​​Security Vulnerability Mitigation​

  • Resolves ​​CVE-2025-0365-class vulnerabilities​​ in IPsec VPN IKEv1 implementation (CVSS 8.2) affecting v6.4.x versions prior to build 0365.
  • Eliminates certificate chain validation bypass in HTTPS deep inspection processes.

2. ​​Performance Optimization​

  • ​20 Gbps Threat Protection Throughput​​: Maintains line-rate inspection with Application Control and IPS enabled.
  • ​35% Memory Utilization Reduction​​: Processes 5,000+ concurrent SSL/TLS sessions with 8 GB RAM.

3. ​​Protocol & Infrastructure Support​

  • ​TLS 1.3 Session Resumption​​: Reduces handshake latency by 35% for financial transaction systems.
  • ​SD-WAN Path Selection​​: Adds native integration with AWS Direct Connect and Azure ExpressRoute.
