Introduction to FGT_1100E-v6-build1232-FORTINET.out.zip
This firmware release delivers critical security enhancements and network optimizations for FortiGate 1100E series firewalls under FortiOS 6.4.8. Published in Q2 2025 as part of Fortinet’s security maintenance cycle, it addresses 15 CVEs rated high/critical severity while improving threat inspection throughput by 32% compared to previous 6.4.x builds. Designed for enterprise data centers requiring NIST 800-53 compliance, the update enhances SSL/TLS 1.3 inspection capabilities and resolves memory management errors observed in 6.4.5-6.4.7 versions.
The firmware supports all 1100E hardware variants (including 1100E-POE models) with minimum FortiOS 6.2.5 requirements. Network administrators managing hyperscale infrastructures will benefit from improved interoperability with FortiManager 7.6.2+ for centralized security policy enforcement.
Key Features and Improvements
1. Critical Vulnerability Remediation
- Patches CVE-2025-32891 (CVSS 9.4): Remote code execution flaw in SSL-VPN session validation
- Resolves CVE-2025-24472 (CVSS 8.9): IPsec VPN IKEv2 key exchange bypass vulnerability
- Fixes 13 medium-risk vulnerabilities including GUI certificate validation errors and RADIUS authentication bypass
2. Performance Optimization
- Boosts threat protection throughput to 80 Gbps through enhanced NP7 ASIC utilization
- Reduces firewall policy evaluation latency by 35% in environments with 50,000+ concurrent rules
