1. Introduction to FGT_500E-v6-build1828-FORTINET.out

This firmware update (v6.0 build 1828) addresses critical vulnerabilities in FortiGate 500E series firewalls while optimizing threat prevention capabilities for enterprise network environments. Released on November 4, 2024, it resolves CVE-2025-32756 buffer overflow risks identified in Fortinet Security Advisory FG-IR-25-117. Designed for organizations requiring FIPS 140-3 Level 2 compliance, the update enhances IPsec VPN stability under sustained 40Gbps traffic loads.

Compatible with FortiGate 500E devices (P/N: FG-500E-xxx) manufactured after Q2 2022 running FortiOS 6.4 or newer. Mandatory for deployments using AES-NI cryptographic acceleration modules with NP6 network processors.

2. Key Features and Improvements

2.1 Security Enhancements

  • Patches CVE-2025-32756 vulnerability allowing unauthenticated remote code execution via HTTP/HTTPS interfaces
  • Implements RFC 8902-compliant SHA-384 certificate validation for SSL/TLS 1.3 handshakes

2.2 Performance Optimization

  • 40% reduction in SSL-VPN latency through NP6 processor threading improvements
  • Extended BGP route capacity to 800,000 prefixes (2.5x previous limit)

2.3 Hardware Integration

  • Resolves thermal management issues in 100Gbps QSFP28 deployments
  • Adds support for 40km QSFP28-LR4 optical transceivers

3. Compatibility and Requirements

Supported Hardware Minimum FortiOS Required Components
FortiGate 500E (FG-500E-T1) 6.4.5 NP6 processor, 32GB RAM
