NVD Description

Note: Versions mentioned in the description apply only to the upstream python2-backports-ssl_match_hostname package and not the python2-backports-ssl_match_hostname package as distributed by RHEL.

The documentation XML-RPC server in Python through 2.7.16, 3.x through 3.6.9, and 3.7.x through 3.7.4 has XSS via the server_title field. This occurs in Lib/DocXMLRPCServer.py in Python 2.x, and in Lib/xmlrpc/server.py in Python 3.x. If set_server_title is called with untrusted input, arbitrary JavaScript can be delivered to clients that visit the http URL for this server.
