CVE-2025-34264 Details
Description
Advantech WISE-DeviceOn Server versions prior to 5.4 contain a stored cross-site scripting (XSS) vulnerability in the /rmm/v1/dog/{agentId} endpoint. When an authenticated user adds or edits Software Watchdog process rules for an agent, the monitored process name is stored in the settings array and later rendered in the Software Watchdog UI without proper HTML sanitation. An attacker can inject malicious script into the process name, which is then executed in the browser context of users who view or interact with the affected rules, potentially enabling session compromise and unauthorized actions as the victim.
A stored cross-site scripting vulnerability has been identified in Advantech WISE-DeviceOn Server versions prior to 5.4. This vulnerability exists in the /rmm/v1/dog/{agentId} endpoint. When an authenticated user adds or edits Software Watchdog process rules for an agent, the monitored process name is saved in the settings array and later displayed in the Software Watchdog user interface without adequate HTML sanitization. This lack of proper input handling allows an attacker to inject malicious scripts into the process name. These scripts are executed in the browser context of users who view or interact with the affected rules, potentially leading to session hijacking and unauthorized actions on behalf of the victim.
Users are advised to update to WISE-DeviceOn Server version 5.4 or later. The update is available on the official Advantech DeviceOn resource page.
