Descriptions

An issue was discovered on D-Link DSR-250N before 3.17B devices. The CGI script upgradeStatusReboot.cgi can be accessed without authentication. Any access reboots the device, rendering it therefore unusable for several minutes.

Se detectó un problema en los dispositivos D-Link DSR-250N versiones anteriores a 3.17B. Se puede acceder al script CGI upgradeStatusReboot.cgi sin autenticación. Cualquier acceso reinicia el dispositivo, haciéndolo por lo tanto inutilizable durante varios minutos

RedTeam Pentesting discovered a denial of service vulnerability in the D-Link DSR-250N device which allows unauthenticated attackers in the same local network to execute a CGI script that reboots the device. Version 3.12 is confirmed affected.
