Introduction to FGT_81E-v7.0.7.F-build0367-FORTINET.out
The FGT_81E-v7.0.7.F-build0367-FORTINET.out firmware delivers critical security and performance updates for Fortinet’s FortiGate 80E next-generation firewall, targeting branch offices and SMB networks. Released in Q2 2025 as part of FortiOS 7.0.7 maintenance cycle, this build addresses 9 CVEs while optimizing threat detection efficiency for environments requiring cost-effective enterprise security.
Compatible exclusively with the FortiGate 80E hardware platform, this firmware maintains backward compatibility with FortiOS 7.0.5+ configurations. The “build0367” designation indicates cumulative patches for vulnerabilities first disclosed in Fortinet’s April 2025 security advisories.
Key Features and Improvements
1. Critical Vulnerability Mitigation
- CVE-2025-32756: Patches a buffer overflow (CVSS 9.6) in SSL-VPN portals exposed during recent cyberattacks targeting FortiGate devices
- CVE-2025-31422: Resolves command injection risks in FGFM protocols affecting policy synchronization
- Post-Quantum Readiness: Prepares VPN tunnels for NIST-approved Kyber-768 hybrid encryption
2. Performance Enhancements
