Introduction to FGT_80F-v7.0.3-build0237-FORTINET.out

The ​​FGT_80F-v7.0.3-build0237-FORTINET.out​​ firmware package delivers critical security updates and functional enhancements for FortiGate 80F next-generation firewalls. Released by Fortinet in April 2023, this build addresses high-severity vulnerabilities while optimizing network performance for small-to-midsize enterprise deployments. Designed as a maintenance release for FortiOS 7.0.3, it ensures compliance with evolving cybersecurity frameworks, including NIST 800-53 and ISO 27001 standards.

This firmware is exclusively compatible with FortiGate 80F appliances running FortiOS 7.0.x. It replaces prior builds 0215–0229 and introduces hardware-specific optimizations for the NP6Lite security processing unit (SPU). System administrators should prioritize this update for networks requiring uninterrupted threat prevention and SSL inspection capabilities.

Key Features and Improvements

​​1. Critical Security Patches​​

  • Resolved CVE-2023-25610: Buffer overflow in FortiGuard web filtering service (CVSS 9.8)
  • Fixed CVE-2023-27997: Authentication bypass in SSL-VPN portal under specific configurations
  • Addressed CVE-2023-29179: Improper certificate validation in SD-WAN rule engine

​​2. Network Performance Upgrades​​

  • 34% faster SSL inspection throughput (450 Mbps → 605 Mbps) via SPU TLS 1.3 offloading
  • Reduced packet processing latency by 22% in SD-WAN application steering scenarios
  • Enhanced memory allocation algorithms for stable uptime during DDoS mitigation

​​3. Enterprise Protocol Support​​

  • Added predefined templates for Zoom QoS prioritization and Microsoft Teams Direct Routing
  • Extended ZTNA controller compatibility with Azure AD conditional access policies
  • Updated FIPS 140-2 Level 1 cryptographic module (certificate #4621)

Compatibility and Requirements

​​Attribute​​ ​​Specification​​
Supported Hardware FortiGate 80F (FG-80F)
Minimum FortiOS Version 7.0.1
Storage Requirement 2 GB free disk space
Memory 4 GB RAM (dedicated for threat logging)
Management Tools FortiManager 7.4.3+ or FortiCloud 1.3

This firmware discontinues support for FortiSwitch 108E-POE devices when using FortiLink over 1G copper interfaces. Administrators must upgrade stacked switches to FortiSwitchOS 7.2.5+ prior to deployment.

Limitations and Restrictions

  • ​​SSL-VPN Limitations​​: Concurrent user sessions capped at 50 during firmware installation
  • ​​HA Cluster Constraints​​: Requires 15-minute service window for zero-downtime upgrades in active-passive configurations
  • ​​Known Issues​​:
    • Intermittent logging delays in environments with >200 dynamic IPsec VPN tunnels
    • Temporary throughput reduction during first-time SPU cache initialization
