Python-based XML-RPC servers may be vulnerable to remote execution of arbitrary code.
Python is an interpreted, interactive, object-oriented, cross-platform programming language.
Graham Dumpleton discovered that XML-RPC servers making use of the SimpleXMLRPCServer library that use the register_instance() method to register an object without a _dispatch() method are vulnerable to a flaw allowing to read or modify globals of the associated module.
A remote attacker may be able to exploit the flaw in such XML-RPC servers to execute arbitrary code on the server host with the rights of the XML-RPC server.
Python users that don't make use of any SimpleXMLRPCServer-based XML-RPC servers, or making use of servers using only the register_function() method are not affected.
All Python users should upgrade to the latest version:
