the Pligg (http://www.pligg.com/) content management system is prone to an SQL-injection vulnerability because it fails to sufficiently sanitize user-supplied data before using it in an SQL query:
To exploit this you need the id of a news you submitted(10 in the example) and an id of a news submitted by others(1 in the example).
When the LIKE statement matches you get a "Not your link" error.
