| Description | 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. |

Solutions
CNA: Replace the non-cryptographic response computation with a digital signature (for example ECDSA P-256) or an HMAC over a fresh per-session random nonce, bound to a stable per-vehicle identifier to prevent cross-bike replay.
