Introduction to FSW_108E-v7-build0102-FORTINET.out Software
This firmware release (build 0102) delivers critical security hardening and operational enhancements for FortiSwitch 108E series devices, addressing vulnerabilities in Layer 2 protocols and Power over Ethernet (PoE) management. Released under Fortinet’s Q2 2025 security update cycle, the update strengthens defenses against MAC flooding attacks and unauthorized port activation attempts observed in enterprise networks.
Compatible exclusively with FSW-108E hardware models, this firmware introduces hardware-accelerated traffic monitoring for 802.3af/at devices and improves energy efficiency by 18% compared to FortiSwitch OS 7.4.1. Network administrators managing small-to-medium business networks will benefit from enhanced LLDP-MED support for VoIP devices and simplified VLAN configurations.
Key Features and Improvements
1. Security Enhancements
- Mitigates CVE-2025-1356: Unauthorized PoE port cycling vulnerability (CVSS 7.5)
- Resolves FG-IR-25-117: Buffer overflow in STP packet processing
- Implements NIST SP 800-193-compliant secure boot validation
2. Performance Optimization
- 30% faster 802.3at power negotiation (900ms → 630ms per port)
- 20% reduction in broadcast storm-induced packet loss
- Improved port security activation times (<0.8sec threshold)
3. Operational Upgrades
- New REST API endpoints for bulk port configuration
- Extended compatibility with Cisco IP Phone 7800 series via LLDP-MED
- Real-time power consumption monitoring per switch stack
