1. Introduction to FGT_90E-v6-build1263-FORTINET.out

This firmware update delivers critical security enhancements and performance optimizations for FortiGate 90E series next-generation firewalls, designed for small-to-medium enterprises requiring robust network protection. As part of FortiOS 6.x architecture, it addresses 11 CVEs identified in Fortinet’s Q2 2024 security advisories while maintaining backward compatibility with existing SD-WAN and VPN configurations.

Optimized for branch office deployments, this build supports hardware-accelerated threat inspection up to 800Mbps firewall throughput. Exclusively compatible with FortiGate 90E hardware variants (FG-90E, FG-90E-POE), it requires minimum 4GB RAM and FortiOS 6.0.8+ baseline installations for deployment.

2. Key Features and Improvements

​​Security Updates​​

  • ​​CVE-2024-23124 Mitigation​​: Patched SSL-VPN heap overflow vulnerability (CVSS 9.4) enabling unauthenticated remote code execution
