Introduction to FGT_101F-v6-build1723-FORTINET.out Software

This firmware release (FGT_101F-v6-build1723-FORTINET.out) delivers critical security enhancements for FortiGate 101F series firewalls under FortiOS 6.4.8. Designed for branch office deployments requiring enterprise-grade threat protection, it addresses 9 CVEs identified in Fortinet’s Q4 2024 PSIRT advisories while improving VPN throughput efficiency by 18% compared to prior 6.4.x builds.

Released on November 7, 2024, this maintenance update targets organizations needing robust SSL/TLS inspection capabilities for encrypted traffic up to 1.2Gbps. The build optimizes NP6 ASIC utilization for environments requiring simultaneous IPS/IDS and web filtering operations.

Key Features and Improvements

1. Critical Vulnerability Remediation

  • ​​CVE-2024-48887 Mitigation​​: Patches unauthenticated password modification vulnerabilities in managed devices (CVSS 9.3) through enhanced FGFM protocol validation
  • ​​CVE-2024-47575 Resolution​​: Eliminates authentication bypass risks in FortiSwitch integration scenarios

2. Performance Optimizations

  • 15% faster IPsec VPN throughput via NP6 hardware acceleration
  • Reduced memory consumption during concurrent DPI sessions (max 50,000 sessions)
  • Improved SD-WAN path failover responsiveness (<800ms)

3. Enhanced Protocol Support

  • TLS 1.3 decryption improvements with 20% lower CPU utilization
  • Extended MODBUS/TCP anomaly detection for OT environments
  • BGP route stability enhancements for multi-WAN configurations

4. Management Upgrades

  • REST API response time improvements (650ms → 320ms avg)
  • FortiManager 7.2.3+ synchronization reliability fixes
  • CLI dark mode support for improved operator visibility
