DESCRIPTION:
Adrian Castro has discovered a vulnerability in VirtueMart Joomla!
eCommerce Edition, which can be exploited by malicious people to
conduct cross-site scripting attacks.

Input passed to the "Itemid" parameter in index.php isn't properly
sanitised before being returned to the user. This can be exploited to
execute arbitrary HTML and script code in a user's browser session in
context of an affected site.

Example:
http://[host]/index.php?option=com_contact&Itemid=[code]

The vulnerability has been confirmed in version 1.0.11. Other
versions may also be affected.

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