Descriptions

An incorrect default permission vulnerability exists in the cgiserver.cgi cgi_check_ability functionality of reolink RLC-410W v3.0.0.136_20121102. The SetMdAlarm API sets the movement detection parameters, giving the ability to set the sensitivity of the camera per a range of hours, and which of the camera spaces to ignore when considering movement detection. Because in cgi_check_ability the SetMdAlarm API does not have a specific case, the user permission will default to 7. This will give non-administrative users the possibility to change the movement detection parameters.

Se presenta una vulnerabilidad de permiso incorrecto por defecto en la funcionalidad cgi_check_ability en el archivo cgiserver.cgi de reolink RLC-410W versión v3.0.0.136_20121102. La API SetMdAlarm establece los parámetros de detección de movimiento, dando la posibilidad de establecer la sensibilidad de la cámara por un rango de horas, y cuál de los espacios de la cámara ignorar cuando es considerada la detección de movimiento. Debido a que en cgi_check_ability la API SetMdAlarm no presenta un caso específico, el permiso del usuario será por defecto 7. Esto dará a usuarios no administrativos la posibilidad de cambiar los parámetros de detección de movimiento
