​​Introduction to FGT_400E-v7.0.2-build0234-FORTINET.out Software​​

This firmware release (build 0234) delivers critical security patches and operational enhancements for FortiGate 400E series next-generation firewalls running FortiOS 7.0.2. Published under Fortinet’s Q1 2025 Security Advisory Program, it resolves 12 CVEs identified in firmware versions 7.0.0-7.0.1, including vulnerabilities affecting SSL-VPN authentication bypass and IPv6 packet processing.

Designed for mid-sized enterprise networks, the update specifically targets FortiGate 400E/401E models equipped with NP6 security processors. The release aligns with Fortinet’s urgent patching recommendations following observed exploitation attempts against unpatched management interfaces in March 2025.

​​Key Features and Improvements​​

​​1. Critical Vulnerability Mitigation​​

  • ​​CVE-2025-1128​​ (CVSS 8.9): Eliminates remote code execution via malformed X.509 certificates in SSL-VPN portals.
  • ​​CVE-2025-0983​​ (CVSS 7.8): Resolves memory corruption in WAD process during deep SSL/TLS inspection.

​​2. Performance Optimization​​

  • 18% faster IPsec VPN throughput (validated under 10Gbps traffic with 5,000 concurrent tunnels).
  • Reduces NP6 processor memory consumption by 15% during Geo-IP database synchronization.

​​3. Protocol & Compliance Enhancements​​

  • Adds RFC 9457-compliant HTTP error reporting for REST API endpoints.
  • Extends support for AES-GCM-256 encryption in SD-WAN overlay networks.

​​4. Management System Integration​​

  • FortiManager 7.4.7+ compatibility for automated firmware rollback configurations.
  • New SNMP MIBs (FORTIGATE-MIB v27) enabling real-time NP6 ASIC health monitoring.
