Zend_XmlRpc in Zend Framework 1.x before 1.11.12 and 1.12.x before 1.12.0 does not properly handle SimpleXMLElement classes, which allows remote attackers to read arbitrary files or create TCP connections via an external entity reference in a DOCTYPE element in an XML-RPC request, aka an XML external entity (XXE) injection attack.

Fix for CVEs: CVE-2012-3363 CVE-2013-1830 CVE-2013-1831 CVE-2013-1832 CVE-2013-1833 CVE-2013-1834 CVE-2013-1835 CVE-2013-1836

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.

Update to 1.11.12 which fixes security issue ZF2012-01: Local file disclosure via XXE injection in Zend_XmlRpc

An XML External Entities inclusion vulnerability was discovered in Zend Framework, a PHP library. This vulnerability may allow attackers to access to local files, depending on how the framework is used.
