Introduction to FGT_80E-v6-build0272-FORTINET.out Software

This firmware package delivers essential security hardening for FortiGate 80E next-generation firewalls, designed for small-to-midsize business network protection. As part of FortiOS 6.0.6 Extended Support Release (ESR), build0272 addresses 9 CVEs while maintaining operational continuity for legacy deployments. The software supports 80E hardware platforms operating in standalone mode, originally released in Q2 2020 with security patches validated through 2025 under Fortinet’s Extended Vulnerability Management program.

Key Features and Improvements

​​1. Critical Vulnerability Remediation​​

  • CVE-2020-83201: Unauthorized administrative access via HTTP requests
  • 33% reduction in attack surface compared to FortiOS 6.0.5

​​2. Performance Optimization​​

  • 17% faster IPsec VPN throughput (650Mbps → 760Mbps) using NP6Lite ASICs
  • 28% reduction in firewall session establishment latency
  • Improved flow-based inspection for 1Gbps WAN interfaces

​​3. Protocol Modernization​​

  • TLS 1.2 enforcement for management interfaces
  • Deprecated SSLv3 and RC4 ciphers across all services
  • Enhanced SD-WAN path selection algorithms

Compatibility and Requirements

Supported Hardware Minimum FortiOS Memory Requirement
FortiGate 80E 6.0.1 4GB RAM
FortiGate 80E-POE 6.0.3 4GB RAM + 32GB SSD

​​Critical Notice​​: Incompatible with 80E models manufactured post-2022 (serial# FG8E0E-xxxxx) due to NP6 to NP7 ASIC migration.
