Introduction to FGT_300E-v6-build1112-FORTINET.out Software

This firmware package delivers essential security updates and network optimization for FortiGate 300E series firewalls running FortiOS 6.2.4. Designed for enterprise branch offices and industrial control environments, it resolves 12 CVEs including critical vulnerabilities in SSL-VPN (CVE-2024-23113) and web filtering services (CVE-2024-47575) while maintaining backward compatibility with existing configurations.

Exclusively compatible with FortiGate 300E hardware (FG-300E, FG-300EF), this build supports hybrid deployments through its multi-VDOM architecture and received Fortinet’s Q3 2024 Operational Stability Certification after 1,500+ hours of field testing. Officially released on November 18, 2024, it extends security maintenance through June 2026 for legacy network environments.
