DESCRIPTION:
Sammy Forgit has discovered a vulnerability in the Art Uploader
module for Joomla!, which can be exploited by malicious people to
compromise a vulnerable system.

The vulnerability is caused due to the
modules/mod_artuploader/upload.php script allowing the upload of
files with arbitrary extensions to a folder inside the webroot. This
can be exploited to execute arbitrary PHP code by uploading a
malicious PHP script.

The vulnerability is confirmed in version 1.0.1. Other versions may
also be affected.

SOLUTION:
Restrict access to the modules/mod_artuploader/upload.php script
(e.g. via .htaccess).

PROVIDED AND/OR DISCOVERED BY:
Sammy Forgit, OpenSysCom.
