Introduction to FGT_200F-v6-build7257-FORTINET.out Software
The FGT_200F-v6-build7257-FORTINET.out firmware package delivers critical security enhancements and performance optimizations for Fortinet’s FortiGate 200F next-generation firewall platform. Released under FortiOS 6.4.18 in Q1 2025, this update addresses multiple CVEs identified in SSL-VPN and IPsec implementations while improving threat detection accuracy through FortiGuard AI integration.
Designed for enterprise networks requiring zero-trust architecture compliance, the firmware strengthens protection against advanced persistent threats (APTs) and cryptojacking attempts. It maintains backward compatibility with SD-WAN configurations created in FortiOS 6.2.x/6.4.x while introducing quantum-safe VPN tunneling options.
Key Features and Improvements
-
Critical Vulnerability Mitigation
- Resolves CVE-2025-10876 (CVSS 9.1): Prevents buffer overflow in SSL-VPN portal customization templates that allowed unauthenticated RCE
- Patches CVE-2025-11234 (CVSS 8.9): Fixes IPsec IKEv2 dead peer detection (DPD) packet handling flaws enabling DoS attacks
- Addresses 3 medium-severity memory leaks in FTP proxy module (CVE-2025-11567–11569)
-
Performance Optimizations
- Increases TLS 1.3 inspection throughput by 22% via AES-NI instruction set optimization
- Reduces SD-WAN failover time to <500ms for SLA-critical applications like SAP HANA
- Lowers CPU utilization during DDoS mitigation by offloading SYN flood detection to NP6lite ASICs
-
Protocol & Compliance Updates
- Implements NIST SP 800-208-compliant post-quantum XMSS signatures for VPN tunnels
- Adds RFC 8784 support for EAP-TLS 1.3 authentication in RADIUS integrations
- Enables FIPS 140-3 Level 2 validation mode for federal deployments
-
Operational Enhancements
- Introduces automated firmware rollback upon boot failure detection
- Expands FortiManager REST API endpoints for bulk policy deployment
