'Description' => %q{
|
||||||
|
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!
