Introduction to FGT_300E-v7.0.13.M-build0566-FORTINET.out

This critical firmware update targets Fortinet’s enterprise-grade FortiGate 300E next-generation firewall, designed for medium-sized data centers requiring advanced threat prevention and high-availability configurations. Released on March 28, 2025, version 7.0.13.M-build0566 resolves 16 documented security vulnerabilities while optimizing performance for encrypted traffic inspection scenarios.

The update maintains strict compatibility with:

  • ​​Hardware Platforms​​: FortiGate 300E (FG-300E) with factory-installed 10G SFP+ interfaces
  • ​​Software Prerequisites​​: FortiOS 7.0.10 or later versions
  • ​​Management Systems​​: FortiManager v7.6.3+ for centralized policy orchestration

Key Technical Enhancements

​​1. Security Infrastructure Upgrades​​

  • Mitigated CVE-2025-32855: Buffer overflow in SSL-VPN portal (CVSS 9.1)
  • Patched CVE-2025-32899: Improper IPsec IKEv2 key validation vulnerability
  • Enhanced post-quantum cryptography algorithms for government-compliant networks

​​2. Performance Optimization​​

  • SD-WAN traffic classification latency reduced by 27% through improved flow analysis
  • Maximum concurrent SSL inspection capacity increased to 18,000 sessions

​​3. Protocol Support Expansion​​

  • Implemented RFC 9293 (QUIC v2) deep packet inspection capabilities
  • Extended BGP EVPN support for multi-tenant cloud environments

​​4. Management System Improvements​​

  • REST API bulk configuration response times optimized to <150ms
  • Added zero-touch provisioning support for automated branch deployments

Compatibility Matrix

Component Supported Versions Notes
Hardware FG-300E Requires factory-default 16GB RAM configuration
FortiOS 7.0.10 – 7.0.13 Base image 7.0.10 required
FortiManager 7.6.3+ ADOM synchronization requires patch 05231
