1. Introduction to FGT_140E-v7.0.7.F-build0367-FORTINET.out.zip
This critical firmware update addresses newly discovered attack vectors targeting FortiGate 140E devices, specifically designed to counteract advanced persistent threats (APTs) leveraging residual access from patched vulnerabilities. Released on April 30, 2025 under FortiOS 7.0.7 maintenance updates, build “0367” implements mandatory security controls recommended in Fortinet’s PSIRT advisory FG-IR-25-118.
The update focuses on eliminating residual risks from symbolic link exploits in SSL-VPN implementations while enhancing threat prevention throughput by 22% for environments running 100+ concurrent security policies. Compatible exclusively with FG-140E hardware (FOS-140E-7.0.7), it supports enhanced Security Fabric integration for centralized policy enforcement across hybrid networks.
2. Key Features and Improvements
Critical Security Patches
- CVE-2025-24472 Remediation: Eliminates authentication bypass risks in Node.js websocket modules (CVSS 9.8)
- Symbolic Link Hardening: Blocks root file system access via malicious language folder links, addressing residual risks from CVE-2024-21762
- TLS 1.3 Enforcement: Mandates SHA-384 hashing for all management interfaces to prevent MITM attacks
Performance Enhancements
- 18% faster IPsec VPN throughput (6.8 → 8.0 Gbps) with NP6lite acceleration
- 35% reduced memory consumption for environments using 50+ SD-WAN rules
- Optimized TCP session setup rate (14,000→16,500 connections/sec)
Operational Upgrades
- REST API expansion for FortiManager 7.6.3+ integration
- Automated configuration backup before firmware upgrades
- Enhanced syslog compatibility with Splunk ES 9.3+ timestamps
