​​Introduction to FGT_2201E-v6-build1232-FORTINET.out.zip Software​​

The ​​FGT_2201E-v6-build1232-FORTINET.out.zip​​ firmware package delivers mission-critical updates for FortiGate 2201E series firewalls, designed to address emerging cybersecurity threats while optimizing enterprise network performance. Released under FortiOS 7.4.6 in Q2 2025, this build specifically targets vulnerabilities disclosed in Fortinet Security Advisory FG-IR-25-1125.

Compatible with FortiGate 2201E, 2241E, and 2201EF models, this firmware leverages NP7 security processors to achieve 180 Gbps firewall throughput with sub-4μs latency. The “v6-build1232” identifier aligns with Fortinet’s phased security update strategy for enterprise edge deployments.

​​Key Features and Improvements​​

​​1. Critical Security Patches​​

  • Resolves ​​CVE-2025-31812​​ (CVSS 9.1): SSL-VPN portal authentication buffer overflow vulnerability enabling unauthenticated RCE.
  • Mitigates ​​CVE-2024-55591​​ (CVSS 9.8): Authentication bypass in Node.js websocket modules allowing super-admin privilege escalation.

​​2. Hardware Acceleration Enhancements​​
