* Version: 6.x, 5.x
* Date: 2010-March-03
* Security risk: Less Critical
* Exploitable from: Remote

-------- DESCRIPTION
---------------------------------------------------------
The AddThis module provides an easy way to share content to over 230
supported services such as Facebook, Email and Twitter. The module did not
