{"id":"CVE-2025-34257","state":"PUBLISHED","title":"Advantech WISE-DeviceOn Server < 5.4 Authenticated Stored XSS via action/defined","description":"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.","publishedAt":"2025-12-05T17:15:24.912Z","updatedAt":"2026-08-14T16:49:27.043Z","severity":{"score":5.1,"label":"Medium","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:L/VI:L/VA:N/SC:L/SI:L/SA:N","source":"VulnCheck"},"assigner":"VulnCheck","products":["Advantech Co., Ltd.
