RELEASE DATE:
2010-11-10
DESCRIPTION:
Salvatore Fresta has discovered a vulnerability in the JQuarks4s
component for Joomla!, which can be exploited by malicious people to
conduct SQL injection attacks.

Input passed via the "q" array index parameter to index.php (when
"option" is set to "com_jquarks4s", "task" is set to "submitSurvey",
and the "q" parameter is set to "4") is not properly sanitised before
being used in SQL queries. This can be exploited to manipulate SQL
queries by injecting arbitrary SQL code.

The vulnerability is confirmed in version 1.0.0. Other versions may
also be affected.

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