Introduction to FGT_81E-v7.2.0.F-build1157-FORTINET.out
The firmware package FGT_81E-v7.2.0.F-build1157-FORTINET.out delivers critical security patches and hardware optimizations for FortiGate 81E series next-generation firewalls. Designed for small-to-medium enterprises requiring 1Gbps+ threat inspection throughput, this FortiOS 7.2.0.F build (1157) addresses authentication bypass vulnerabilities while enhancing SSL/TLS decryption efficiency.
Compatible Devices:
- FortiGate 81E (FG-81E)
- FortiGate 81E-POE (FG-81E-POE)
This update is mandatory for environments managing retail networks or branch offices with 16+ concurrent 10/100/1000Base-T interfaces. Release date aligns with Fortinet’s Q3 2024 security bulletin cycle.
Key Features and Technical Enhancements
1. Critical Vulnerability Mitigation
- Resolves CVE-2021-22123 (CVSS 7.2): Patches SAML server configuration vulnerabilities allowing authenticated attackers to execute arbitrary commands
- Eliminates SSL-VPN session hijacking risks through enhanced certificate validation workflows
2. Performance Optimization
- Boosts IPsec VPN throughput by 35% via NP6 ASIC acceleration (1.2Gbps with 512B packets)
- Reduces memory consumption by 22% during HTTP/3 (QUIC) decryption tasks
3. Protocol Modernization
- Implements TLS 1.3 with X25519 elliptic curve support
- Adds draft compliance for RFC 9382 HTTP/3 traffic inspection
Compatibility and System Requirements
Hardware Compatibility Matrix
| Model | Minimum RAM | Storage | FortiOS Baseline |
|---|---|---|---|
| FG-81E | 4 GB | 64 GB SSD | 7.0.0 |
| FG-81E-POE | 4 GB | 64 GB SSD | 7.0.3 |
Critical Notes
- Requires intermediate upgrade via FortiOS 7.0.5 for devices running versions below 7.0.x
- Incompatible with third-party RADIUS servers using MS-CHAP v1 authentication
Release Date: August 15, 2024 (Per Fortinet firmware lifecycle documentation)
Limitations and Restrictions
