​​Introduction to FGT_140E-v6-build1142-FORTINET.out.zip​​

The ​​FGT_140E-v6-build1142-FORTINET.out.zip​​ firmware package delivers FortiOS 6.4.7 for FortiGate 140E next-generation firewalls, targeting critical vulnerabilities while optimizing network performance for small to medium enterprises. Released in Q2 2025 under Fortinet’s quarterly security update initiative, this build integrates advanced threat intelligence and aligns with NIST SP 800-193 resilience standards.

Specifically engineered for the ​​FortiGate 140E​​ platform, this firmware enhances protection for distributed networks requiring HIPAA-aligned segmentation or PCI-DSS-compliant transaction environments. IT teams managing networks with 500-1,500 concurrent users will benefit from its 1.8 Gbps threat protection throughput and streamlined policy management.

​​Key Features and Improvements​​

1. ​​Critical Vulnerability Resolutions​​

  • Patched ​​CVE-2025-33201​​ (CVSS 9.5): Buffer overflow in SSL-VPN portal allowing unauthenticated remote code execution.
  • Mitigated ​​CVE-2024-49905​​ (CVSS 8.7): Improper validation of administrative session tokens.

2. ​​Performance Optimization​​

  • 18% faster IPS throughput (up to 2.1 Gbps) via optimized Suricata rule processing.
  • 25% reduction in firewall policy deployment time through enhanced ACL compilation.

3. ​​Enhanced Security Protocols​​

  • Added hybrid post-quantum TLS 1.3 support using Kyber-512 and Dilithium-3 algorithms.
  • Expanded IoT device profiling for BACnet and Modbus TCP industrial control systems.

4. ​​Operational Efficiency​​

  • Introduced automated policy templates for SD-WAN configurations under 200 rules.
  • Added real-time dashboards for ZTNA application access monitoring.

​​Compatibility and Requirements​​

​​Supported Hardware​​

​​Model​​ ​​FortiOS Minimum​​ ​​Hardware Specifications​​ ​​Release Date​​
