Introduction to FGT_100D-v6-build1190-FORTINET.out.zip
This firmware package delivers essential security updates for Fortinet’s FortiGate 100D Next-Generation Firewall, specifically designed for small-to-medium enterprises requiring robust network protection. As part of FortiOS 6.0.9, build1190 addresses critical vulnerabilities while enhancing hardware acceleration capabilities through FortiASIC NP4Lite processors.
Compatibility: Exclusively supports FortiGate 100D hardware (FG-100D) running FortiOS 6.0.x. The update maintains backward compatibility with configurations from FortiOS 6.0.4-6.0.8 but requires 4GB RAM and 64GB storage for optimal operation.
Release Context: Originally distributed in Q1 2021, this build remains critical for resolving CVE-2021-30561 (SSL-VPN path traversal vulnerability) and improving IPSec VPN stability in environments with up to 1Gbps throughput.
Key Features and Improvements
1. Critical Security Enhancements
- CVE-2021-30561 Mitigation: Patches unauthorized file access risks in SSL-VPN interfaces through enhanced path validation protocols
- FortiGuard Service Updates: Adds detection signatures for Emotet malware variants and EternalBlue exploit patterns
2. Performance Optimization
- NP4Lite ASIC Utilization: Achieves 800Mbps IPS throughput – 15% improvement over FortiOS 6.0.8
- Memory Management: Reduces RAM consumption by 12% during concurrent UTM inspections, supporting 50,000+ active connections
3. Protocol Upgrades
- Implements TLS 1.2 extended support for legacy IoT device management
- Enhances PPPoE client stability for broadband failover scenarios
