Descriptions

An untrusted deserialization was found in the org.apache.xmlrpc.parser.XmlRpcResponseParser:addResult method of Apache XML-RPC (aka ws-xmlrpc) library. A malicious XML-RPC server could target a XML-RPC client causing it to execute arbitrary code. Apache XML-RPC is no longer maintained and this issue will not be fixed.

Se detectó una deserialización no confiable en el método org.apache.xmlrpc.parser.XmlRpcResponseParser:addResult de la biblioteca Apache XML-RPC (también se conoce como ws-xmlrpc). Un servidor XML-RPC malicioso podría apuntar a un cliente XML-RPC causando que ejecute código arbitrario. Apache XML-RPC ya no se mantiene y este problema no será solucionado.

A flaw was discovered where the XMLRPC client implementation in Apache XMLRPC, performed deserialization of the server-side exception serialized in the faultCause attribute of XMLRPC error response messages. A malicious or compromised XMLRPC server could possibly use this flaw to execute arbitrary code with the privileges of an application using the Apache XMLRPC client library.

Guillaume Teissier reported that the XMLRPC client in libxmlrpc3-java, an XML-RPC implementation in Java, does perform deserialization of the server-side exception serialized in the faultCause attribute of XMLRPC error response messages. A malicious XMLRPC server can take advantage of this flaw to execute arbitrary code with the privileges of an application using the Apache XMLRPC client library.
