Secunia

Graham Dumpleton has reported a vulnerability in Python, which can be exploited by malicious people to bypass certain security restrictions.

The vulnerability is caused due to an error in the SimpleXMLRPCServer library module, where the internals of registered objects or modules are not properly protected. This may be exploited to disclose and modify sensitive information and potentially execute arbitrary code.

Successful exploitation requires that a vulnerable XML-RPC server registers an object via the "register_instance()" method without a "_dispatch()" method.

The vulnerability has been reported in all versions of 2.2, 2.3 versions prior to 2.3.5, and in version 2.4.
