MediumCVSS 4.3Exploitation Probability (EPSS)
Low risk1th percentile - higher than 1% of all known CVEs
Summary
A vulnerability in the Wireless Control Module (WCM) of the 2025 Indian Motorcycle Scout Bobber + Tech 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.
Risk Assessment
The risk is that an attacker can gain unauthorized access to the motorcycle by unlocking it without knowing the PIN, potentially leading to theft or manipulation of its systems.
Recommendation
It is recommended to immediately apply patches provided by the vendor once available and implement a stronger authentication mechanism based on cryptographic challenge-response.
