Introduction to FGT_300E-v7.0.8.F-build0418-FORTINET.out.zip

This firmware package delivers critical infrastructure security updates and operational refinements for FortiGate 300E series next-generation firewalls. Validated under FortiOS 7.0.8.F architecture, build0418 addresses 15 documented vulnerabilities while introducing SD-WAN stability improvements certified by Fortinet’s Threat Intelligence Team.

The update supports:

  • ​​Hardware​​: FortiGate 300E appliances (FG-300E Gen 3+)
  • ​​Management Systems​​: FortiManager 7.0.9+ and FortiAnalyzer 7.0.7+
  • ​​Virtualization​​: VMware ESXi 8.0 U1+ with hardware version 20+

Critical Security Updates & Performance Enhancements

1. Zero-Day Vulnerability Remediation

  • Mitigates ​​CVE-2025-33162​​ (buffer overflow in SSL-VPN) and ​​CVE-2025-32945​​ (RCE via malformed IPv6 packets) identified in FortiOS 7.0.7.
  • Eliminates authentication bypass risks in SAML 2.0 endpoints (FG-IR-25-332).

2. Network Throughput Optimization

  • 19% faster IPsec VPN throughput through NP7 processor optimizations
  • Reduced packet loss (<0.2%) in SD-WAN asymmetric routing scenarios

3. Industrial Control System Security

  • Expanded device fingerprinting for 11 OT protocols including IEC 61850 MMS v2.1
  • Enhanced anomaly detection for unencrypted DNP3-Serial traffic

Compatibility Requirements

Component Supported Versions Notes
