AI Powered Q&A
Can you explain this vulnerability to me?
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/action/schedule endpoint where an authenticated user can add a schedule with a name that is stored without proper HTML sanitation. Malicious scripts injected into the schedule name can then be executed in the browsers of users who view or interact with the affected schedule, potentially leading to session compromise and unauthorized actions.
How can this vulnerability impact me? :
This vulnerability can impact you by allowing attackers to execute malicious scripts in your browser when you view or interact with a compromised schedule. This can lead to session hijacking, unauthorized actions performed on your behalf, and potential compromise of sensitive information or control within the affected system.
What immediate steps should I take to mitigate this vulnerability?
Users are strongly advised to update Advantech WISE-DeviceOn Server to version 5.4 or later, where the vulnerability has been fixed. [1, 3]
