A Controller Area Network (CAN) Bus standard vulnerability could impact the security of automobiles and other products across a range of industries. CAN is a standard that allows communication between various mechanisms in modern cars. Attackers trying to take advantage of the CAN flaw would need physical access to the car. The severity of the attack depends upon the ease with which an external party can access an input port, usually via the onboard diagnostics standard known as ODB-II. The vulnerability is harder to detect than other potential vulnerabilities, which are often picked up by intrusion detection systems.”]
