CVE-2025-34257

Advantech WISE-DeviceOn Server versions prior to 5.4 contain a stored cross-site scripting (XSS) vulnerability in the /rmm/v1/action/defined endpoint. When an authenticated user creates a task, the defined_name value is stored and later rendered in the Overview page without HTML sanitization. An attacker can inject malicious script into defined_name, which is then executed in the browser context of users who view the affected task, potentially enabling session compromise and unauthorized actions as the victim.

Summary		(es) Versiones de Advantech WISE-DeviceOn Server anteriores a 5.4 contienen una vulnerabilidad de cross-site scripting (XSS) almacenado en el endpoint /rmm/v1/action/defined. Cuando un usuario autenticado crea una tarea, el valor defined_name se almacena y luego se renderiza en la página Overview sin saneamiento HTML. Un atacante puede inyectar script malicioso en defined_name, que luego se ejecuta en el contexto del navegador de los usuarios que ven la tarea afectada, lo que podría permitir el compromiso de la sesión y acciones no autorizadas como la víctima.
