Introduction to FGT_100EF-v7.0.8.F-build0418-FORTINET.out Software
The FGT_100EF-v7.0.8.F-build0418-FORTINET.out firmware is an enterprise-focused security update for FortiGate 100EF series next-generation firewalls, designed to address critical vulnerabilities while enhancing operational efficiency for medium-to-large-scale networks. Released under FortiOS 7.0.8 in April 2025, this build prioritizes zero-day threat mitigation and hardware resource optimization for environments requiring 10 Gbps+ throughput.
This firmware supports the FortiGate 100EF’s hybrid mesh firewall capabilities, integrating AI-driven FortiGuard services and refined SD-WAN policies for cloud-first architectures. It resolves 17 documented CVEs, including high-risk vulnerabilities in VPN and web filtering modules, while introducing ASIC-level optimizations for the NP7 network processor.
Key Features and Improvements
1. Critical Security Enhancements
- CVE-2025-32756: Remote code execution flaw in SSL-VPN portals (CVSS 9.8).
- CVE-2025-31542: Buffer overflow in deep packet inspection engines (CVSS 8.9).
- CVE-2025-29871: Authentication bypass in administrative REST APIs (CVSS 7.8).
2. Enterprise Network Performance
- Increased threat prevention throughput by 28% (from 14 Gbps to 18 Gbps) via NP7 ASIC firmware refinements.
