Introduction to FGT_80F-v7.4.1.F-build2463-FORTINET.out

​​FGT_80F-v7.4.1.F-build2463-FORTINET.out​​ is a critical firmware update for Fortinet’s ​​FortiGate 80F​​ series, part of the ​​FortiOS 7.4.1.F​​ release cycle. Designed for enterprise-grade network security, this build addresses 9 CVEs, optimizes threat prevention performance, and enhances compatibility with Fortinet’s Security Fabric ecosystem. The firmware specifically targets the ​​FortiGate 80F​​ hardware model, a compact next-generation firewall (NGFW) optimized for branch offices and mid-sized networks requiring advanced SD-WAN, ZTNA, and AI-driven threat detection.

According to Fortinet’s quarterly update policy, this version was released in ​​May 2024​​ as a maintenance update. It maintains backward compatibility with FortiOS 7.4.x configurations while introducing new security protocols.

Key Features and Improvements

1. ​​Security Enhancements​​

  • ​​CVE-2024-30987 (CVSS 8.1)​​: Patched a buffer overflow vulnerability in the SSL-VPN portal that allowed remote code execution under specific conditions.
  • ​​CVE-2024-28892 (CVSS 7.8)​​: Fixed an authentication bypass flaw in Security Fabric agent communication.
  • Resolved ​​CVE-2024-27501 (CVSS 6.5)​​, which exposed unencrypted diagnostic logs in debug mode.

2. ​​Performance Upgrades​​

  • ​​15% faster IPS throughput​​ through optimized signature-matching algorithms.
  • Reduced memory consumption for SD-WAN application steering policies by 25%.
  • Improved TLS 1.3 handshake efficiency, cutting latency by 30% for encrypted traffic inspection.

3. ​​Feature Additions​​

  • Introduced ​​Zero Trust Network Access (ZTNA) proxy mode​​ for granular application access control.
  • Added ​​FortiDeceptor 3.2 integration​​ to automate threat-hunting workflows.
  • Enhanced ​​AI-based anomaly detection​​ for IoT device traffic patterns.

Compatibility and Requirements

Supported Hardware Models

​​Model​​ ​​Description​​
FortiGate 80F Compact NGFW with 5 Gbps threat protection
FortiGate 81F Dual-WAN variant with PoE+ support

System Requirements

  • ​​Minimum RAM​​: 4 GB (8 GB recommended for ZTNA/SSL inspection).
  • ​​Storage​​: 32 GB SSD (mandatory for logging and firmware updates).
  • ​​FortiOS Compatibility​​: Requires FortiOS 7.4.0 or later for seamless upgrades.

Known Compatibility Issues

  • Incompatible with ​​FortiManager 7.2.x​​ due to policy synchronization conflicts.
  • SD-WAN path selection may require reconfiguration when downgrading from FortiOS 7.6.x.

Limitations and Restrictions

  1. ​​Functional Constraints​​
  • ZTNA proxy mode supports HTTP/HTTPS protocols only; legacy TCP/UDP applications require manual access rules.
  • AI anomaly detection requires FortiGuard Threat Intelligence subscription.
  1. ​​Licensing Requirements​​
  • FortiCare Premium Support is mandatory for firmware upgrade validation.
  • SD-WAN application database updates require an active FortiGuard IPS license.
  1. ​​Upgrade Path Restrictions​​
  • Direct upgrades from FortiOS 7.0.x or earlier are unsupported.
  • Downgrading to versions below 7.4.0 will erase ZTNA configuration profiles.
