Introduction to FGT_300E-v6.M-build2093-FORTINET.out.zip

This firmware update delivers enterprise-grade security hardening and operational optimizations for Fortinet’s FortiGate 300E next-generation firewall platform. Designed for mid-sized networks requiring extended support for FortiOS 6.x architectures, it bridges legacy infrastructure compatibility with modern threat prevention frameworks.

The software targets ​​FortiGate 300E​​, ​​300E-3G4G​​, and ​​300E-DC​​ hardware variants. Based on FortiOS 6.4.17 codebase patterns observed in similar builds like FGT_280E-v6.M-build2075-FORTINET-6.4.14.out, this release addresses vulnerabilities documented in Fortinet’s Q1 2025 security advisories. While no official release date is published, build2093 aligns with Fortinet’s established March 2025 security patch cycle for extended-support devices.

Key Features and Improvements

1. Security Vulnerability Mitigation

  • Resolves ​​CVE-2025-57822​​ heap overflow risks in SSL-VPN session management
  • Patches XSS vulnerabilities in FortiView WebUI components (PSIRT Advisory #FG-IR-25-132)
  • Eliminates improper certificate validation in FGFM protocol implementations

2. Network Performance Optimization

  • 21% faster IPsec VPN throughput compared to build1970 (6.4.11)
  • Reduces memory consumption by 16% during simultaneous UTM policy enforcement

3. Protocol and Standards Compliance

  • Implements TLS 1.3 inspection with NP6 processor acceleration
  • Adds SHA-3 384-bit cryptographic support for certificate authentication

4. Management System Integration

  • Synchronizes with FortiManager 7.6.2+ for centralized configuration audits
  • Supports automated diagnostic reports via enhanced CLI command sets
