Traction-control disablement via hard-coded credentials
Published Aug 27, 2026 · Updated Aug 27, 2026
Use of hard-coded credentials in Bendix EC-80 Electronic Controller firmware allows attackers to disable automatic traction control. CISA identifies embedded credentials but does not disclose their value, storage locus, or the authenticated command path that changes traction-control behavior. Exploitation requires unauthenticated access to the vehicle-adjacent communications path, and the reported consequence is limited to traction-control integrity and availability.
