Description Florian Weimer 2013-04-12 14:21:57 UTC
python-bugzilla uses the default xmlrpclib transports, which are based on classes in httplib which do not perform server certificate checking.  As a result, man-in-the-middle attacks on the HTTPS connection are possible.

Comment 19 Jan Lieskovsky 2013-06-19 16:10:04 UTC
It was found that python-bugzilla, a Python library for interacting with Bugzilla instances over XML-RPC functionality, did not perform X.509 certificate verification when using secured SSL connection. A man-in-the-middle (MiTM) attacker could use this flaw to spoof Bugzilla server via an arbitrary certificate.

This issue was discovered by Florian Weimer of the Red Hat Product Security Team.
