Vulnerability from variot

Toyota 2017 Model Year DCU (Display Control Unit) allows an unauthenticated attacker within Bluetooth range to cause a denial of service attack and/or execute an arbitrary command. The affected DCUs are installed in Lexus (LC, LS, NX, RC, RC F), TOYOTA CAMRY, and TOYOTA SIENNA manufactured in the regions other than Japan from Oct. 2016 to Oct. 2019. An attacker with certain knowledge on the target vehicle control system may be able to send some diagnostic commands to ECUs with some limited availability impacts; the vendor states critical vehicle controls such as driving, turning, and stopping are not affected. Made by Toyota DCU ( Display control unit ) To BlueBorne There is a vulnerability resulting from the vulnerability in. This vulnerability information is provided by the developer for the purpose of disseminating it to product users. JPCERT/CC Report to JPCERT/CC Coordinated with the developer.By a third party DCU Service luck against ? Interference (DoS) An attack could be carried out or an arbitrary command could be implemented. Also, DCU There is a possibility that operations will be performed on the vehicle via.
