Detailsinfo

A vulnerability was found in Toyota RAV4 2021. It has been rated as critical. This issue affects an unknown code of the component ECU Message Handler. The manipulation with an unknown input leads to a injection vulnerability. Using CWE to declare the problem leads to CWE-74. The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Toyota RAV4 2021 vehicles automatically trust messages from other ECUs on a CAN bus, which allows physically proximate attackers to drive a vehicle by accessing the control CAN bus after pulling the bumper away and reaching the headlight connector, and then sending forged "Key is validated" messages via CAN Injection, as exploited in the wild in (for example) July 2022.

The weakness was shared 04/06/2023. The advisory is shared at kentindell.github.io. The identification of this vulnerability is CVE-2023-29389 since 04/05/2023. Technical details are unknown but an exploit is available. MITRE ATT&CK project uses the attack technique T1055 for this issue.
