Vulnerability from github – Published: 2026-05-29 09:31 – Updated: 2026-05-29 15:30

Details

Weak authentication in the Wireless Control Module (WCM) of the Indian Motorcycle Scout Bobber + Tech 2025 model year allows an adjacent-network attacker with read access to the in-vehicle network to recover the user-set unlock PIN by passively observing a single PIN authentication exchange. The Infotainment Digital Round display computes its response using a non-cryptographic operation rather than a cryptographic challenge-response, so the PIN is mathematically derivable from one captured exchange, defeating the motorcycle's primary user-authentication control. Specific protocol details have been withheld pending vendor remediation.
