Vulnerability Note VU#320516
Windows Media Player 9 ActiveX control does not adequately validate access to Windows Media Library
An ActiveX control included with Windows Media Player 9 does not adequately validate script access to the Windows Media Library. This could allow an attacker to read or modify data contained in the library.
Windows Media Player 9 includes an ActiveX control that can be used to provide a playback interface for media objects on web sites. The ActiveX control does not adequately validate script access the Windows Media Library. From MS03-021:
The Windows Media Player 9 Series ActiveX control uses the Windows Media Player public object model, and provides access to the media library under certain conditions. The Windows Media Player 9 Series ActiveX control is a scriptable component, meaning that script code can be used to invoke or control it. The ActiveX control does not properly validate requests made by script to access the Media Library.
If a victim browses an attacker-controlled web site with Internet Explorer (IE), the attacker could read and modify information in the Windows Media Library and possibly determine the victim's username. The media library contains metadata about media objects such as title, duration, and artist and track names. By modifying an entry in the library (or creating a new entry), an attacker may be able to mislead a victim into opening a media object of the attacker's choice. In conjunction with other vulnerabilities, this could lead to more serious impacts, including the execution of arbitrary code.
