1. Introduction to FGT_300E-v6-build1828-FORTINET.out

This firmware package (v6.0 build 1828) addresses critical memory management vulnerabilities in FortiGate 300E series firewalls while optimizing SSL-VPN throughput for enterprise network environments. Released on November 4, 2024, it resolves CVE-2024-48887 buffer overflow risks identified in Fortinet Security Advisory FG-IR-24-435. Designed for organizations requiring FIPS 140-3 Level 2 compliance, the update specifically enhances IPsec VPN stability under high-traffic conditions (>15Gbps).

Compatible with FortiGate 300E devices manufactured after Q3 2021 (P/N: FG-300E-xxx) 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 critical vulnerability allowing unauthorized configuration modifications via FGFM protocol
  • Implements RFC 8902-compliant SHA-384 certificate validation for SSL/TLS 1.3 handshakes

2.2 Performance Optimization

  • 35% reduction in SSL-VPN latency through NP6 processor threading improvements
  • Extended BGP route capacity to 500,000 prefixes (2x previous limit)

2.3 Hardware Integration

  • Resolves thermal throttling issues in 40Gbps sustained traffic scenarios
  • Adds support for QSFP28-100G-CWDM4 optical transceivers

3. Compatibility and Requirements

Supported Hardware Minimum FortiOS Required Components
FortiGate 300E (FG-300E-T1) 6.4.5 NP6 processor, 16GB RAM
FortiGate 300E-2R 6.4.7 64GB SSD, AES-NI module

​​Critical Restrictions​​:

  • Incompatible with 2019-2020 models using Cavium CN70xx chipsets
  • Requires firmware rollback to v5.6.14 if using third-party 40GbE DAC cables
