Introduction to FWF_60E_DSL-v6-build1175-FORTINET.out Software
This firmware update addresses critical vulnerabilities in FortiWifi 60E DSL devices operating on legacy FortiOS 6.0 architectures. Released under Fortinet’s Extended Support Program (ESP) in August 2025, build 1175 provides targeted security hardening for distributed branch networks while maintaining backward compatibility with discontinued hardware features.
Designed exclusively for FortiWifi 60E DSL integrated security appliances, this firmware bridges gaps between end-of-support (EOS) and end-of-life (EOL) phases. The update resolves 17 documented vulnerabilities from Fortinet’s Q2 2025 PSIRT advisory, including three critical-rated exploits affecting DSL modem configurations.
