CVE-2024-6347

ECU service interruption via unauthenticated UDS commands

Published Aug 15, 2024 · Updated Aug 15, 2024

Missing authentication in Nissan Altima 2022 blind-spot ECU firmware allows attackers to interrupt ECU operation via a UDS session. The ECU accepts entry to its privileged programming session and control commands without authentication or precondition checks. Access to the vehicle's UDS network is required; attackers can disrupt normal blind-spot ECU operation, including triggering a service interruption.
