An elevation of privilege vulnerability exists when the Windows Universal Plug and Play (UPnP) service improperly allows COM object creation. An attacker who successfully exploited this vulnerability could run arbitrary code with elevated system privileges. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

To exploit this vulnerability, an attacker would have to log on to an affected system and run a specially crafted script or application.

The update addresses the vulnerability by correcting how the Windows UPnP service accesses COM objects.
