Deferred Deferred - Pending Action
CAN Bus-Off State Vulnerability in Indian Motorcycle Scout Bobber + Tech 2025

Publication date: 2026-05-29

Last updated on: 2026-05-29

Assigner: Automotive Security Research Group (ASRG)

Description
Expected behavior violation in the in-vehicle network of the Indian Motorcycle Scout Bobber + Tech 2025 model year allows an adjacent-network attacker to bypass the motorcycle's anti-theft shutdown by forcing the Wireless Control Module (WCM) into the CAN bus-off state. Using a well-known CAN error-frame injection technique against a periodic WCM transmission, the attacker drives the WCM CAN controller's transmit error counter past the bus-off threshold, after which the WCM stops transmitting all messages, including the shutdown command. Peer ECUs do not interpret WCM silence as a security event and continue normal operation, allowing the motorcycle to be operated despite the immobilizer never having been unlocked. Specific protocol details have been withheld pending vendor remediation.

Can you explain this vulnerability to me?

This vulnerability is an expected behavior violation in the in-vehicle network of the Indian Motorcycle Scout Bobber + Tech 2025 model year. An attacker on an adjacent network can exploit this by forcing the Wireless Control Module (WCM) into a CAN bus-off state using a known CAN error-frame injection technique. When the WCM enters this state, it stops transmitting all messages, including the anti-theft shutdown command. Other electronic control units (ECUs) do not recognize the WCM's silence as a security issue and continue normal operation, allowing the motorcycle to be operated even though the immobilizer has not been unlocked.


How can this vulnerability impact me? :

The impact of this vulnerability is that an attacker can bypass the motorcycle's anti-theft system, allowing unauthorized operation of the vehicle. Since the Wireless Control Module stops sending shutdown commands and other ECUs do not detect this as a security event, the motorcycle can be started and used despite the immobilizer remaining locked. This effectively disables the anti-theft protection, increasing the risk of theft.


How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:

The provided information does not specify any direct impact of this vulnerability on compliance with common standards and regulations such as GDPR or HIPAA.
