SOFTWARE:
IDoBlog 1.x (component for Joomla)
http://secunia.com/product/18973/

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

Input passed to the "userid" parameter in the Joomla! installation's
index.php script (when "option" is set to "com_idoblog" and "task" to
"userblog") 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. Other versions may
also be affected.

SOLUTION:
Filter malicious characters and character sequences in a proxy.
