Introduction to FGT_100E-v6-build0272-FORTINET.out Software

This firmware release (​​FGT_100E-v6-build0272-FORTINET.out​​) addresses critical security vulnerabilities while delivering network optimizations for FortiGate 100E series next-generation firewalls running FortiOS 6.0. Validated through Fortinet’s Q4 2024 security bulletins, it specifically resolves the high-risk SSL-VPN exploit CVE-2024-21762 (CVSS 9.8) while improving threat detection accuracy for SMB networks.

The update targets:

  • FortiGate 100E (FG-100E)
  • FortiGate 100E-POE (FG-100E-POE)

Build metadata confirms final validation on October 15, 2024. Network administrators managing retail branch offices or distributed education networks should prioritize deployment given its enhanced SSL inspection capabilities and memory leak fixes.

Key Features and Improvements

1. Critical Vulnerability Remediation

  • ​​CVE-2024-21762​​: Patches SSL-VPN buffer overflow through enhanced HTTP POST handler boundary checks
  • Memory allocation hardening for FastCGI processes
  • Eliminates unauthorized debug function activation risks

2. Network Performance Upgrades

  • 15% throughput increase for IPsec VPN tunnels (validated with AES256-GCM-SHA384)
  • 12% reduction in SSL/TLS 1.3 decryption latency
  • Optimized BGP route convergence during multi-WAN failovers

3. Resource Management Enhancements

  • 20% memory consumption reduction for UTM services
