goform/formEMR30 in Sumavision Enhanced Multimedia Router (EMR) 3.0.4.27 allows creation of arbitrary users with elevated privileges (administrator) on a device, as demonstrated by a setString=new_user<*1*>administrator<*1*>123456 request.
The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.
