Security Announcement

Zend_XmlRpc is vulnerable to XML eXternal Entity (XXE) Injection attacks. 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.

The Request and Response implementations in Zend_XmlRpc were patched to ensure libxml_disable_entity_loader() is invoked prior to instantiating any SimpleXML objects. This disables XXE parsing, and thus disables the attack vector.

This patch has been applied starting in versions 1.11.12 and 1.12.0 of Zend Framework, and has been ported to the upcoming version 2.0.0 development branch (and will be included starting with the 2.0.0beta5 release).

The Zend Framework team thanks the following for working with us to help
protect its users:
