Description

The remote host contains an ActiveX control from SunnComm called AxWebRemoveCtrl. This control was likely installed by requesting an uninstaller for SunnComm's MediaMax digital rights management software used, for example, on select Sony CDs.

By design, AxWebRemoveCtrl allows any website to cause the control to download and execute code from an arbitrary URL. Should a user visit a maliciously crafted website, this would allow that website to execute arbitrary code on the remote host.
