A vulnerability in a common PHP extension module could allow a remote attacker to execute code on a vulnerable system.
XML-RPC is a specification and a set of implementations that allow software running on disparate operating systems and in different environments to make procedure calls over the Internet. XML-RPC uses HTTP for the transport protocol and XML for the data encoding. Several independent implementations of XML-RPC exist for PHP applications.
A common flaw in the way that several XML-RPC PHP implementations pass unsanitized user input to eval() within the XML-RPC server results in a vulnerability that could allow a remote attacker to execute code on a vulnerable system. An attacker with the ability to upload a crafted XML file could insert PHP code that would then be executed by the web application using the vulnerable XML-RPC code.
Remote attackers may be able to execute PHP code of their choosing on a vulnerable system. The code would be executed in the context of the server program that runs the corresponding web application. Secondary impacts of a compromised web service account include, but are not limited to, malicious modification of web site data, information disclosure, and access that may be leveraged to gain additional system privileges.
