Detailsinfo

A vulnerability was found in Indian Motorcycle Scout Bobber and Tech 2025. It has been rated as problematic. Affected by this issue is some unknown functionality of the component Wireless Control Module. The manipulation with an unknown input leads to a weak authentication vulnerability. Using CWE to declare the problem leads to CWE-1390. The product uses an authentication mechanism to restrict access to specific users or identities, but the mechanism does not sufficiently prove that the claimed identity is correct. Impacted is confidentiality. CVE summarizes:

Weak authentication between the Wireless Control Module (WCM) and the Engine Control Module (ECM) 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 per-vehicle ECM immobilizer secret by passively observing a single seed/key exchange. The WCM derives its response using a reversible, non-cryptographic operation rather than a cryptographic challenge-response, so the persistent immobilizer secret can be reconstructed from one captured exchange. With this secret the attacker can authenticate to the ECM independently of the WCM and start the engine, defeating the immobilizer. Specific protocol details have been withheld pending vendor remediation.

The weakness was presented by Scott Sheahan. This vulnerability is handled as CVE-2026-49323 since 05/29/2026. The exploitation is known to be easy. The attack needs to be approached locally. No form of authentication is required for exploitation. Successful exploitation requires user interaction by the victim. There are neither technical details nor an exploit publicly available.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
