Name of the Vulnerable Software and Affected Versions
Softing AG OPC Toolbox versions prior to 4.10.1.13036
Description
The issue allows for Stored XSS via the
ITEMLISTVALUES##ITEMID parameter in the "/en/diag values.html" API endpoint, resulting in JavaScript payload injection into the trace file. This payload will then be triggered every time an authenticated user browses the page containing it.Recommendations
For versions prior to 4.10.1.13036, as a temporary workaround, consider restricting access to the "/en/diag values.html" API endpoint to minimize the risk of exploitation. Avoid using the
ITEMLISTVALUES##ITEMID parameter in the affected API endpoint until the issue is resolved.Exploit
