FKIE_CVE-2026-49324

Vulnerability from fkie_nvd - Published: 2026-05-29 13:16 - Updated: 2026-07-21 12:10
Severity
4.6 (Medium) - CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Summary
Uncontrolled resource consumption in the Wireless Control Module (WCM) of the Indian Motorcycle Scout Bobber + Tech 2025 model year allows an adjacent-network attacker with write access to the in-vehicle network to permanently immobilize the motorcycle. The WCM enforces a brute-force lockout on the immobilizer authentication algorithm, but the lockout counter is reachable by any unauthenticated message, has no session binding, and does not reset on power cycle. An attacker can deliberately trip the lockout with a small number of crafted frames, leaving the bike un-startable until dealer service. Specific thresholds have been withheld pending vendor remediation.

El WCM impone un bloqueo por fuerza bruta en el algoritmo de autenticaci\u00f3n del inmovilizador, pero el contador de bloqueo es accesible por cualquier mensaje no autenticado, no tiene vinculaci\u00f3n de sesi\u00f3n y no se reinicia al apagar y encender. Un atacante puede activar deliberadamente el bloqueo con un peque\u00f1o n\u00famero de tramas manipuladas, dejando la motocicleta inoperable hasta el servicio del concesionario. Se han retenido umbrales espec\u00edficos a la espera de la remediaci\u00f3n del proveedor."
