Introduction to FGT_140D_POE-v6-build1319-FORTINET.out
This firmware package (v6.2.12 build1319) delivers critical security enhancements and performance optimizations for FortiGate 140D Power over Ethernet (PoE) series firewalls. Designed for mid-sized enterprises requiring PoE-enabled network security, it resolves 14 documented vulnerabilities while maintaining backward compatibility with FortiOS 6.2.x configurations.
The update specifically targets the FortiGate 140D PoE model (FG-140D-POE), a legacy device still widely deployed in distributed office networks. Release notes indicate this build prioritizes stability for environments running older hardware, with 98% of compatibility validations completed against 2016-era network infrastructure.
Key Features and Improvements
1. Security Enhancements
- CVE-2024-41538 (CVSS 9.1): Patches a buffer overflow vulnerability in SSL-VPN web portal authentication.
- CVE-2024-42279 (CVSS 8.5): Mitigates cross-site scripting (XSS) risks in SD-WAN rule management interfaces.
Performance Optimization
- 18% improvement in IPSec VPN throughput (up to 720 Mbps) through NP4 ASIC driver optimizations.
- Reduced memory consumption in DHCP server processes by 32%, enhancing stability during large-scale IP assignments.
Protocol Support Updates
- Added TLS 1.3 cipher suite compatibility for legacy hardware acceleration.
- Extended RADIUS attribute support for IEEE 802.1X authentication in PoE environments.
