Introduction to FGT_60E_DSLJ-v7.0.11.M-build0489-FORTINET.out

This firmware update resolves 5 critical vulnerabilities in Fortinet’s FortiGate 60E-DSL Next-Generation Firewall series, including mitigation for CVE-2025-30122 (CVSS 9.8) – a buffer overflow risk in PPPoE authentication modules. Released on May 10, 2025, it enhances DSL link stability through improved error correction algorithms while maintaining 150 Mbps threat-inspected throughput for SMB network environments.

Specifically engineered for FG-60E-DSL hardware models, this build introduces enhanced ADSL2+/VDSL2 vectoring support under FortiOS 7.0.11.M. Network administrators managing remote branch offices with legacy copper infrastructure should prioritize deployment to comply with TR-069 device management standards.

Key Security & Technical Enhancements

1. Critical Vulnerability Mitigation
