The Advantech WISE-DeviceOn Server prior to version 5.4 is susceptible to a stored cross-site scripting (XSS) vulnerability found in the /rmm/v1/plugin-config/dashboards/menus endpoint. An authenticated user can exploit this flaw while adding or modifying dashboard entries, resulting in malicious scripts being executed in the browsers of users interacting with the affected dashboards.
