Introduction to FGT_100E-v7.2.0.F-build1157-FORTINET.out Software
The FGT_100E-v7.2.0.F-build1157-FORTINET.out firmware package is a pivotal update for Fortinet’s FortiGate 100E next-generation firewall, delivering enhanced security protocols and performance optimizations tailored for enterprise network environments. As part of FortiOS 7.2.0, this build focuses on addressing critical vulnerabilities while introducing advanced threat prevention capabilities for hybrid infrastructure.
Compatible Devices:
- FortiGate 100E (P/N: FG-100E) with existing FortiOS 7.0.x/7.2.x installations
- FortiManager 7.2.3+ for centralized policy orchestration
Based on documentation from Fortinet’s technical bulletins, this firmware (build 1157) was released in Q3 2022 to resolve 14 documented security flaws and improve interoperability with SD-WAN architectures.
Key Features and Improvements
1. Critical Security Enhancements
- CVE-2022-42475 Mitigation: Patched a heap-based buffer overflow vulnerability in SSL-VPN that allowed remote code execution (CVSS 9.6).
- FortiGuard AI-Powered Threat Detection: Upgraded IPS signatures to detect Log4j 2.x exploits and APT41 lateral movement patterns.
2. Performance Optimizations
- NP7 Lite ASIC Utilization: Achieved 18% faster IPsec VPN throughput (up to 2.5 Gbps) using AES-256-GCM encryption.
- Memory Management: Reduced memory leaks in web filtering processes during high-concurrency HTTPS traffic.
3. Protocol & Compliance Upgrades
- TLS 1.3 Full Decryption: Added support for hybrid post-quantum key exchange (X25519-Kyber768) in HTTPS inspection.
- NIST SP 800-193 Compliance: Enabled firmware integrity validation through hardware-rooted trust measurements.
4. Legacy Protocol Support
- Maintained compatibility with Windows Server 2012 R2 RADIUS authentication.
- Preserved functionality for 3G/4G USB modem failover configurations.
Compatibility and Requirements
| Component | Supported Versions |
|---|---|
| FortiGate Hardware | FG-100E (P/N: P27210F100E series) |
| FortiOS | 7.0.9+, 7.2.0+ |
| FortiManager | 7.2.3+, 7.4.1+ |
| FortiAnalyzer | 7.2.5+, 7.4.0+ |
Release Date: August 23, 2022
Critical Notes:
- Incompatible with FG-100E devices manufactured before 2019 (PCB Rev. < 3.2).
- Requires 2GB free storage on the root partition for audit log retention enhancements.
Limitations and Restrictions
-
Feature Constraints:
- SD-WAN application steering requires FortiOS 7.4+ for machine learning-based path selection.
- ZTNA agent compatibility limited to FortiClient 7.0.12+ endpoints.
-
Known Issues:
- Intermittent false positives in industrial protocol (DNP3) traffic classification (workaround: disable “Deep Inspection” mode).
- Syslog timestamp drift observed when forwarding to Splunk 9.0+ (fixed in build 1163).
