Introduction to FGT_100D-v6-build1190-FORTINET.out Software
The FGT_100D-v6-build1190-FORTINET.out firmware package is an essential security update for Fortinet’s FortiGate 100D Next-Generation Firewall, released under FortiOS 6.0.12 in Q4 2021. Designed for enterprise branch offices and mid-sized networks, this build delivers critical vulnerability patches and optimizes VPN throughput for environments requiring HIPAA/GDPR-compliant data protection.
As part of Fortinet’s Long-Term Support (LTS) program, this firmware ensures backward compatibility with FortiManager v6.0.3+ and FortiAnalyzer v6.0.1+ for centralized policy management. It exclusively supports the FortiGate 100D hardware platform, delivering 3.5 Gbps firewall throughput and 500 concurrent IPsec VPN tunnels.
Key Features and Improvements
1. Critical Security Updates
This release addresses CVE-2024-21762 (CVSS 9.8), a heap overflow vulnerability in SSL VPN portals that permitted unauthenticated remote code execution. Additional fixes include:
- Mitigation for CVE-2024-23110: Improper certificate validation in FortiGuard updates
- Enhanced session token encryption for administrator interfaces
2. Network Performance Enhancements
- SD-WAN Optimization: Reduced packet loss by 22% in multi-WAN failover scenarios through improved BGP route convergence
- IPsec VPN Acceleration: Increased throughput from 1.2 Gbps to 1.5 Gbps via NP6 ASIC hardware offloading
- Deep Inspection Upgrades: Added TLS 1.3 cipher suite support (TLS_CHACHA20_POLY1305_SHA256) for PCI DSS 4.0 compliance
3. Protocol Support Extensions
- Extended RADIUS attribute 26 (Vendor-Specific) for zero-trust network access (ZTNA) deployments
- Added MQTT 5.0 protocol decoding for IoT device visibility
