La respuesta a una solicitud PROFINET DCP con un paquete PROFINET DCP especialmente dise\u00f1ado podr\u00eda causar una condici\u00f3n de denegaci\u00f3n de servicio del sistema solicitante.

El \u00e9xito de la explotaci\u00f3n no requiere ninguna interacci\u00f3n del usuario o privilegios y afecta a la disponibilidad de la funcionalidad principal del dispositivo afectado. Se requiere un reinicio manual para recuperar el sistema. En el momento de la publicaci\u00f3n del aviso no se conoce ninguna explotaci\u00f3n p\u00fablica de esta vulnerabilidad de seguridad.
