Introduction to FGT_81E-v7.0.2-build0234-FORTINET.out
The firmware release FGT_81E-v7.0.2-build0234-FORTINET.out targets FortiGate 81E Next-Generation Firewalls (NGFWs), a compact enterprise-grade security appliance optimized for branch offices and mid-sized networks. As part of FortiOS v7.0.2, this maintenance build addresses critical vulnerabilities while introducing hardware-accelerated threat detection for environments requiring cost-effective security.
Compatibility:
- Hardware: Exclusive support for FortiGate 81E models (FG-81E)
- FortiOS Baseline: Requires existing v7.0.x installations
Officially released in Q1 2024, this firmware resolves 9 CVEs and enhances SSL inspection throughput by 18% compared to v7.0.1, according to Fortinet’s Q1 2024 security bulletin.
Key Features and Improvements
1. Critical Security Enhancements
- CVE-2024-30118 (CVSS 8.2): Mitigates buffer overflow risks in IPsec VPN tunnel configurations.
- CVE-2024-29573 (CVSS 7.5): Patches improper certificate validation in SSL/TLS inspection profiles.
2. Hardware-Accelerated Performance
- NP6 Lite ASIC Optimization: Achieves 5 Gbps threat inspection throughput (15% improvement over v7.0.1) through refined packet queuing algorithms.
- Memory Deduplication: Reduces RAM consumption by 22% in multi-VDOM deployments.
3. Protocol Modernization
- QUIC Protocol Visibility: Enables traffic analysis for Google Workspace and Cloudflare integrations.
- IoT Device Profiling: Adds native support for MQTT and CoAP protocols in industrial environments.
