Vulnerability Summary

CVE-2025-34259: Advantech WISE-DeviceOn Server versions prior to 5.4 contain a stored cross-site scripting (XSS) vulnerability in the /rmm/v1/devicemap/building endpoint. When an authenticated user creates a map entry, the name parameter is stored and later rendered in the map list UI without HTML sanitzation. An attacker can inject malicious script into the map entry name, which is then executed in the browser context of users who view or interact with the affected map entry, potentially enabling session compromise and unauthorized actions as the victim.
