SOFTWARE:
SimpleFAQ 2.x (component for Joomla)
http://secunia.com/product/15426/

DESCRIPTION:
k1tk4t has discovered a vulnerability in the SimpleFAQ component for
Joomla, which can be exploited by malicious people to conduct SQL
injection attacks.

Input passed to the "aid" parameter in the Joomla installation's
index.php script (when "option" is set to "com_simplefaq" and "task"
to "answer") is not properly sanitised before being used in SQL
queries. This can be exploited to manipulate SQL queries by injecting
arbitrary SQL code.

Successful exploitation allows e.g. retrieving administrator
usernames and password hashes.

The vulnerability is confirmed in version 2.40 and reported in
version 2.11. Other versions may also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised.
