VERIFY ADVISORY:
http://secunia.com/advisories/30490/

CRITICAL:
Moderately critical

IMPACT:
Manipulation of data, Exposure of sensitive information

WHERE:
>From remote

SOFTWARE:
MyContent 1.x (component for Joomla)
http://secunia.com/product/18929/

DESCRIPTION:
His0k4 has discovered a vulnerability in the MyContent component for
Joomla!, which can be exploited by malicious people to conduct SQL
injection attacks.

Input passed to the "id" parameter in the Joomla! installation's
index.php script (when "option" is set to "com_mycontent" and "task"
to "view") 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 password
hashes, but requires knowledge of the database table prefix.

The vulnerability is confirmed in version 1.1.13. Other versions may
also be affected.

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