Vendor / Product:

the commercial forums out there.
How can XennoBB be described in few words?
Lightning-speed, stable, SECURED(?) and modern.

Original advisory:
http://www.surfionline.com/security_advisories/20060819_xennobb_icon_topic_sql.txt
------------------- DESCRIPTION -------------------
An exploit exists in the above mentioned versions of XennoBB which
can be exploited by malicious users to conduct SQL injection attacks.
Input passed to the "icon_topic" parameter in topic_post.php is not
properly sanitised before being used in an SQL query. This exploit
can lead to manipulation of SQL queries by injecting arbitary SQL code.
--------------------- EXPLOIT ---------------------
Submit a forged POST request to
topic_post.php?action=post&fid={forum ID here}
With the following as the POST data:
form_sent=1&form_user={username here}&req_subject=Subject&req_message=Message&submit=1&icon_topic=[SQL]
Successful exploitation leads would lead to the SQL query in the icon_topic
parameter being run.
--------------------- SOLUTION --------------------
Ensure input is properly sanitized before being used in a database
query.
