PEAR XML-RPC, phpxmlrpc: New PHP script injection vulnerability The PEAR XML-RPC and phpxmlrpc libraries allow remote attackers to execute arbitrary PHP script commands. pear-xml_rpc phpxmlrpc August 24, 2005 August 24, 2005: 01 102378 102576 remote 1.4.0 1.4.0 1.2-r1 1.2-r1

The PEAR XML-RPC and phpxmlrpc libraries are both PHP implementations of the XML-RPC protocol.

Stefan Esser of the Hardened-PHP Project discovered that the PEAR XML-RPC and phpxmlrpc libraries were improperly handling XMLRPC requests and responses with malformed nested tags.

A remote attacker could exploit this vulnerability to inject arbitrary PHP script code into eval() statements by sending a specially crafted XML document to web applications making use of these libraries.

There are no known workarounds at this time.
