Joomla! Googlemaps plugin vulnerability.....

Joomla! Googlemaps plugin vulnerability

The problem with the Joomla! Googlemaps plugin lies in the fact anyone can request the /plugins/system/plugin_googlemap2_proxy.php in their browser or script, to execute cURL HTTP requests to remote websites.

The url parameter is vulnerable for Cross Site Scripting (XSS) attacks, and allows the retrieval of remote website content. When this happens a lot, a website becomes overloaded and unresponsive, making a Denial-of-Service attack succesfully executed.

Update: Removing the plugin helps only to remove the XSS vulnerability, but NOT the overload problem, as still botnets will try to access the plugin. You should also add the following in the top of your .htaccess file in the main Joomla directory:

<Files "plugin_googlemap2_proxy.php">
Order Deny,Allow
deny from all
</Files>
