DESCRIPTION:
A vulnerability has been discovered in the U Extended Comment plugin
for WordPress, which can be exploited by malicious users to disclose
sensitive information.
Input passed via the "fileurl" parameter to index.php (when
"_wpnonce" is set and "uexc_attach_download" is set to "true") is not
properly verified in
wp-content/plugins/u-extended-comment/includes/attachment.php before
being used to download files. This can be exploited to download
arbitrary files from local resources via directory traversal
sequences.
Successful exploitation requires "Attachment" permissions.
The vulnerability is confirmed in version 1.0.1. Prior versions may
also be affected.
SOLUTION:
Update to version 1.0.2 or later.
PROVIDED AND/OR DISCOVERED BY:
The vendor credits Julio Potier.
