Descriptions

The denial-of-service can be triggered by transmitting a carefully crafted CAN frame on the same CAN network as the vulnerable node. The frame must have a CAN ID matching an installed filter in the vulnerable node (this can easily be guessed based on CAN traffic analyses). The frame must contain the opposite RTR bit as what the filter installed in the vulnerable node contains (if the filter matches RTR frames, the frame must be a data frame or vice versa).

La denegación de servicio puede activarse transmitiendo un frame CAN cuidadosamente manipulada en la misma red CAN que el nodo vulnerable. El frame debe tener una ID CAN que coincida con un filtro instalado en el nodo vulnerable (esto se puede adivinar fácilmente basándose en los análisis de tráfico CAN). El frame debe contener el bit RTR opuesto al que contiene el filtro instalado en el nodo vulnerable (si el filtro coincide con frame RTR, el frame debe ser un frame de datos o viceversa).
