Description
Incorrect behavior order in the Infotainment / Digital Round display of the Indian Motorcycle Scout Bobber + Tech 2025 model year allows an adjacent-network attacker to bypass the PIN entry screen. The Infotainment uses presence of Wireless Control Module (WCM) traffic during its boot window as a proxy for whether an immobilizer is fitted; if no WCM messages are observed, it skips the PIN entry screen and shows the normal user interface. An attacker who silences the WCM during the boot window — for example via a separately tracked CAN bus-off technique — can present a fully unlocked Infotainment despite the PIN never being entered. Specific timing and protocol details have been withheld pending vendor remediation.
