Python: Arbitrary code execution through SimpleXMLRPCServer

Python: Arbitrary code execution through SimpleXMLRPCServer Python-based XML-RPC servers may be vulnerable to remote execution of arbitrary code. Python 2005-02-08 2005-02-08 80592 remote 2.3.4-r1 2.3.3-r2 2.2.3-r6 2.3.4

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:


    # emerge --sync
    # emerge --ask --oneshot --verbose dev-lang/python
