CVE-2025-34262Advantech WISE-DeviceOn Server < 5.4 Authenticated Stored XSS via devices/name/{agent_id}
Medium 5.1
In plain English
A medium-severity cross-site scripting in WISE-DeviceOn Server from Advantech Co., Ltd.. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.2% (higher than 14% of all known vulnerabilities).
Official description
Advantech WISE-DeviceOn Server versions prior to 5.4 contain a stored cross-site scripting (XSS) vulnerability in the /rmm/v1/devices/name/{agent_id} endpoint. When an authenticated user renames a device, the new_name value is stored and later rendered in device listings or detail views without proper HTML sanitation. An attacker can inject malicious script into the device name, which is then executed in the browser context of users who view or interact with the affected device, potentially enabling session compromise and unauthorized actions as the victim.
