SECUNIA ADVISORY ID:
SA37868

VERIFY ADVISORY:
http://secunia.com/advisories/37868/

DESCRIPTION:
A vulnerability has been discovered in the BF Survey Pro component
for Joomla, which can be exploited by malicious people to conduct SQL
injection attacks.

Input passed via the "catid" parameter to index.php (when "option" is
set to "com_bfsurvey_profree" and "view" is set to "bfsurveyprofree")
is not properly sanitised before being used in an SQL query. This can
be exploited to manipulate SQL queries by injecting arbitrary SQL
code.

The vulnerability is confirmed in BF Survey Pro Free version 1.2.6.
Other versions may also be affected.

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