The Zend Framework team reports:
The XmlRpc package of Zend Framework is vulnerable to XML
eXternal Entity Injection attacks (both server and client).
The SimpleXMLElement class (SimpleXML PHP extension) is used
in an insecure way to parse XML data. External entities can be
specified by adding a specific DOCTYPE element to XML-RPC
requests. By exploiting this vulnerability an application may be
coerced to open arbitrary files and/or TCP connections.
Additionally, the Zend_Dom, Zend_Feed, Zend_Soap, and
Zend_XmlRpc components are vulnerable to XML Entity Expansion
(XEE) vectors, leading to Denial of Service vectors. XEE attacks
occur when the XML DOCTYPE declaration includes XML entity
definitions that contain either recursive or circular references;
this leads to CPU and memory consumption, making Denial of
Service exploits trivial to implement.
