Introduction to FGT_300E-v7.0.11.M-build0489-FORTINET.out

This firmware release addresses 6 critical vulnerabilities in Fortinet’s FortiGate 300E Next-Generation Firewall series, including resolution for CVE-2025-30125 (CVSS 9.8) – a heap-based buffer overflow risk in SSL-VPN web portals. Released on May 10, 2025, it enhances threat detection accuracy through updated FortiGuard AI models while supporting 2 Gbps threat-inspected throughput for enterprise network environments.

Designed exclusively for FG-300E and FGR-300E hardware models, this build introduces quantum-resistant encryption prototypes under FortiOS 7.0.11.M. Network administrators managing mid-sized enterprises should prioritize deployment to comply with NIST SP 800-193 firmware integrity requirements.
