Name of the Vulnerable Software and Affected Versions Sumavision Enhanced Multimedia Router (EMR) version 3.0.4.27

Description The issue allows creation of arbitrary users with elevated privileges, specifically as administrators, on a device. This can be achieved through a request such as "goform/formEMR30" with a "setString=new user<1>administrator<1>123456" parameter. The vulnerability is related to errors in security mechanisms and can be exploited remotely.

Recommendations For version 3.0.4.27, consider restricting access to the "goform/formEMR30" endpoint to minimize the risk of exploitation. As a temporary workaround, avoid using the setString parameter in the affected endpoint until the issue is resolved.
