DESCRIPTION:
Sammy Forgit has discovered a vulnerability in the Hungred Post
Thumbnail plugin for WordPress, which can be exploited by malicious
people to compromise a vulnerable system.

The vulnerability is caused due to the
wp-content/plugins/font-uploader/font-upload.php script improperly
validating the extension of an uploaded file. This can be exploited
to execute arbitrary PHP code by uploading a PHP file with an
appended ".jpg", ".gif", or ".png" file extension.

Successful exploitation requires that Apache is not configured to
handle the mime-type for media files with a ".jpg", ".gif", or ".png"
extension (Configured to handle by default).

The vulnerability is confirmed in version 2.1.9. Other versions may
also be affected.

SOLUTION:
Restrict access to the
wp-content/plugins/font-uploader/font-upload.php script or the
wp-content/uploads/hungred-post-thumbnail/images/random/ folder (e.g.
via .htaccess).

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