CVE-2026-18268

Kenwood DNR1007XR JKGenService Command Injection Local Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of Kenwood DNR1007XR devices. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the JKGenService. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of root. Was ZDI-CAN-29066.

Summary		(es) Vulnerabilidad de inyección de comandos con escalada de privilegios local en JKGenService de Kenwood DNR1007XR. Esta vulnerabilidad permite a los atacantes locales escalar privilegios en instalaciones afectadas de dispositivos Kenwood DNR1007XR. Un atacante debe obtener primero la capacidad de ejecutar código con bajos privilegios en el sistema objetivo para explotar esta vulnerabilidad. La falla específica existe dentro del JKGenService. El problema resulta de la falta de validación adecuada de una cadena proporcionada por el usuario antes de usarla para ejecutar una llamada al sistema. Un atacante puede aprovechar esta vulnerabilidad para escalar privilegios y ejecutar código arbitrario en el contexto de root. Fue ZDI-CAN-29066.
