CVE-2025-34260 is a medium-severity vulnerability affecting advantech wise-deviceon_server. It was published on December 5, 2025 and has a CVSS 3.1 base score of 5.4 (MEDIUM).
This vulnerability has a CVSS 3.1 base score of 5.4, rated MEDIUM. It can be exploited remotely over the network. Some level of privileges is required for exploitation.
Technical Description
Advantech WISE-DeviceOn Server versions prior to 5.4 contain a stored cross-site scripting (XSS) vulnerability in the /rmm/v1/action/schedule endpoint. When an authenticated user adds a schedule to an existing task, the schedule name is stored and later rendered in schedule listings without HTML sanitation. An attacker can inject malicious script into the schedule name, which is then executed in the browser context of users who view or interact with the affected schedule, potentially enabling session compromise and unauthorized actions as the victim.
Remediation
Check the references section for vendor advisories and patches from advantech. Update wise-deviceon_server to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
