Synopsis
The remote web server is running an outdated instance of Magento Community Edition (CE) that is affected by an XML external entity (XXE) injection attack vector.
Description
Versions of Magento CE prior to 1.7.0.1 are affected by an XXE injection vulnerability due to improper parsing of XML data in the 'Zend_XmlRpc_Server()' class. A remote, unauthenticated attacker can exploit this vulnerability to view arbitrary files on the remote host.
Solution
Upgrade to Magento CE version 1.7.0.1 or later.
