The HP Virtual Rooms ActiveX control contains methods that can be used to download and execute arbitrary code from an arbitrary server.
HP Virtual Rooms is software for online collaboration. HP Virtual Rooms requires Internet Explorer, as one of the components is an ActiveX control called HPVirtualRooms32, which is provided by the file HPVirtualRooms32.dll. The HPVirtualRooms32 ActiveX control contains dangerous methods, but does not place any restrictions on which web sites can use the control. These methods can be used to download and execute arbitrary code from an arbitrary server.
By convincing a user to view a specially crafted HTML document (e.g., a web page or an HTML email message or attachment), an attacker may be able to execute arbitrary code with the privileges of the user.
