Introduction to FGT_80CM-v5-build1727-FORTINET.out Software

This firmware package delivers critical security patches and system optimizations for ​​FortiGate 80CM​​ next-generation firewalls under FortiOS 5.6.14. Designed for small-to-medium branch offices, it addresses 9 documented vulnerabilities while optimizing hardware resource utilization and protocol handling efficiency.

​​Compatibility​​: Validated exclusively for ​​FortiGate 80CM hardware​​ (FG-80CM models) with CP8 ASIC acceleration. Incompatible with platforms requiring FortiOS 6.x/7.x due to architectural differences in memory management.

​​Version Details​​:

  • ​​Build Number​​: 1727 (FortiOS 5.6.14)
  • ​​Release Date​​: Q4 2017 (per Fortinet’s firmware lifecycle documentation for 5.6.x).

Key Features and Improvements

1. ​​Security Vulnerability Resolutions​​

  • ​​CVE-2017-3145​​: Mitigates buffer overflow risks in SSL VPN portals (CVSS 8.1).
  • ​​CVE-2017-4830​​: Fixes session validation bypass in web filtering modules.
  • Enhanced XSS protection for administrative interfaces to prevent unauthorized script execution.

2. ​​Performance Enhancements​​

  • ​​15% faster IPsec VPN throughput​​ (up to 450 Mbps) via optimized SPU hardware offloading.
  • Reduced memory fragmentation during sustained operations (>30 days uptime).

3. ​​Protocol & Feature Upgrades​​
