TITLE:
Joomla! McQuiz Component "tid" SQL Injection

SECUNIA ADVISORY ID:
SA28940

VERIFY ADVISORY:
http://secunia.com/advisories/28940/

CRITICAL:
Moderately critical

IMPACT:
Manipulation of data, Exposure of sensitive information

WHERE:
From remote

SOFTWARE:
McQuiz 0.x (component for Joomla)
http://secunia.com/product/17581/

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

Input passed to the "tid" parameter in the Joomla! installation's
index.php script (when "option" is set to "com_mcquiz", "task" to
"user_tst_shw", and "Itemid" to a valid item ID) 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, but requires knowledge of the database
table prefix.

The vulnerability is confirmed in version 0.9 Final. Other versions
may also be affected.

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