Introduction to FGT_80F_POE-v7.4.2.F-build2571-FORTINET.out Software
This firmware package delivers FortiOS 7.4.2 for FortiGate 80F Power over Ethernet (PoE) series appliances, engineered to enhance network security and power management in distributed office environments. Released through Fortinet’s firmware distribution channels in Q3 2025, build 2571 addresses critical vulnerabilities while optimizing PoE device management and IoT security protocols.
Specifically designed for FortiGate 80F PoE models, this update supports 24-port PoE++ configurations with 95W per port capacity. The release aligns with Fortinet’s quarterly security update cycle, prioritizing firmware validation processes similar to those seen in GitHub Actions workflows for cross-platform builds.
Key Features and Improvements
1. Critical Infrastructure Protection
Patches 13 CVEs identified through FortiGuard Labs’ threat intelligence:
- CVE-2025-49940: Buffer overflow in PoE management interface
- CVE-2025-48885: Improper authentication in Power over Ethernet control module
2. Enhanced Device Management
- 35% faster PoE device discovery and classification
- Dynamic power budgeting for 802.3bt-compliant endpoints
3. Security Validation Enhancements
