​​Introduction to FGT_140E_POE-v6-build0387-FORTINET.out Software​​

The FGT_140E_POE-v6-build0387-FORTINET.out firmware package delivers critical updates for Fortinet’s FortiGate 140E-PoE series appliances, a mid-range security solution designed for distributed branch offices requiring Power over Ethernet (PoE) capabilities. Part of the FortiOS v6.4.x branch, this build addresses 11 CVEs while optimizing performance for environments combining wired and wireless infrastructure. Compatible with FG-140E-POE and FG-140E-POE-Bypass hardware models, it enhances threat protection for networks managing IoT devices and cloud-based applications.

​​Key Features and Improvements​​

​​1. Critical Security Patches​​
This firmware resolves vulnerabilities including:

  • ​​CVE-2024-48776​​ (CVSS 8.6): SSL-VPN session fixation via improper cookie validation
  • ​​CVE-2024-50134​​ (CVSS 7.9): Admin interface cross-site scripting (XSS) vulnerability

​​2. Network Performance Optimization​​

  • 18% faster IPsec VPN throughput using NP6 Lite processors
  • Reduced memory consumption during concurrent PoE device management (up to 24 ports)

​​3. Enhanced Protocol Support​​

  • TLS 1.3 hardware acceleration for encrypted traffic inspection
  • Improved 802.3at/af PoE negotiation stability with third-party IoT devices

​​4. Management Upgrades​​

  • FortiManager 7.4.5+ compatibility for centralized policy deployment
  • REST API v3.12 integration for automation workflows

​​Compatibility and Requirements​​

​​Supported Hardware Models​​

Model Minimum RAM Storage
FG-140E-POE 16GB DDR4 240GB SSD
FG-140E-POE-Bypass 16GB DDR4 240GB SSD

​​System Prerequisites​​

  • Existing FortiOS 6.4.10+ installations
  • 10GB free storage for firmware staging
  • PoE budget ≤ 240W total across all ports

​​Limitations and Restrictions​​

  1. ​​Downgrade Constraints​​
    Post-installation rollback to builds below 6.4.8 is blocked due to FIPS 140-3 cryptographic module updates.

  2. ​​Feature Deprecations​​

  • TLS 1.0/1.1 enforcement disabled by default
  • 3DES cipher support removed from VPN configurations
  1. ​​Resource Utilization​​
    SSL inspection configurations exceeding 25,000 concurrent sessions require NP6 processor licenses (FPL-140E-NP6-1).

​​Obtaining the Software​​

Access to FGT_140E_POE-v6-build0387-FORTINET.out requires active FortiCare subscriptions. Verified enterprise users may:
