Introduction to FGT_300E-v6-build0457-FORTINET.out.zip Software
The FGT_300E-v6-build0457-FORTINET.out.zip firmware package delivers essential updates for Fortinet’s FortiGate 300E Next-Generation Firewall (NGFW), part of the FortiOS v6.4.x Long-Term Support (LTS) branch. Released in Q4 2024, this build (0457) addresses 9 critical vulnerabilities, enhances SD-WAN traffic prioritization, and introduces hardware stability improvements for mid-sized enterprise deployments.
Designed for networks requiring 25 Gbps firewall throughput and 8 Gbps SSL inspection capacity, the FortiGate 300E supports hybrid architectures integrating Zero Trust principles. This firmware maintains backward compatibility with appliances running FortiOS v6.4.32 or newer, ensuring seamless upgrades for existing configurations.
Key Features and Improvements
1. Critical Security Enhancements
- CVE-2024-47575 Mitigation: Patches an SSL-VPN session token validation flaw that allowed unauthorized access through replay attacks.
- CVE-2024-48887 Resolution: Fixes a GUI vulnerability enabling unauthenticated password resets via crafted HTTP requests.
- FortiGuard AI Updates: Adds 14 new IPS signatures targeting Log4j-derived exploits and ShadowPad C2 traffic patterns.
2. Performance Optimization
- NP6 ASIC Hardware Offloading: Improves IPsec VPN throughput by 18% on 10 GbE interfaces through enhanced packet processing algorithms.
- Memory Allocation: Reduces RAM consumption during BGP route synchronization by 12% (from 3.9 GB to 3.4 GB at 400k routes).
3. Protocol & Management Upgrades
- SD-WAN Application Steering: Introduces QoS prioritization rules for Microsoft Teams Direct Routing and Zoom Phone traffic.
- FortiManager Integration: Supports bulk policy deployment via FortiManager v7.4.5+ with automated pre-upgrade configuration backups.
