Executive Summary

This vulnerability is a stored cross-site scripting (XSS) issue in Advantech WISE-DeviceOn Server versions prior to 5.4. It occurs in the /rmm/v1/devicemap/plan endpoint where an authenticated user can add an area to a map entry. The 'name' parameter of this area is stored without proper HTML sanitization. An attacker can inject malicious scripts into this area name, which are then executed in the browsers of users who view or interact with the affected map entry, potentially leading to session compromise and unauthorized actions.

Impact Analysis

This vulnerability can impact you by allowing attackers to execute malicious scripts in your browser when you view or interact with the affected map entries. This can lead to session compromise, where attackers may hijack your session, and unauthorized actions performed on your behalf within the application.

Detection Guidance

Detection involves verifying if the Advantech WISE-DeviceOn Server version is prior to 5.4 and checking for stored XSS payloads in the /rmm/v1/devicemap/plan endpoint, specifically in the 'name' parameter of area entries. Since the vulnerability requires authenticated access, you can audit the map entries for suspicious scripts in area names. There are no specific commands provided, but manual inspection or automated scanning of the endpoint for stored scripts in area names can help detect exploitation. [1]

Mitigation Strategies

The immediate mitigation step is to update the Advantech WISE-DeviceOn Server to version 5.4 or later, where the vulnerability has been fixed by proper sanitization of the 'name' parameter in the /rmm/v1/devicemap/plan endpoint. Additionally, restrict authenticated user privileges to limit who can add or modify area names in map entries to reduce risk until the update is applied. [1]
