NOTE(melwitt): This is the combination of two commits, the bug fix and a followup change to the unit test to enable it also run on Python < 3.6. Our console proxies (novnc, serial, spice) run in a websockify server whose request handler inherits from the python standard SimpleHTTPRequestHandler. There is a known issue [1] in the SimpleHTTPRequestHandler which allows open redirects by way of URLs in the following format: http://vncproxy.my.domain.com//example.com/%2F.. which if visited, will redirect a user to example.com. We can intercept a request and reject requests that pass a redirection URL beginning with "//" by implementing the SimpleHTTPRequestHandler.send_head() method containing the vulnerability to reject such requests with a 400 Bad Request. This code is copied from a patch suggested in one of the issue comments [2]. Closes-Bug: #1927677 [1] https://bugs.python.org/issue32084 [2] https://bugs.python.org/issue32084#msg306545 Conflicts: nova/tests/unit/console/test_websocketproxy.py NOTE(melwitt): The conflict is because change I23ac1cc79482d0fabb359486a4b934463854cae5 (Allow TLS ciphers/protocols to be configurable for console proxies) is not in Train. NOTE(melwitt): The difference from the cherry picked change: HTTPStatus.BAD_REQUEST => 400 is due to the fact that HTTPStatus does not exist in Python 2.7. Reduce mocking in test_reject_open_redirect for compat This is a followup for change Ie36401c782f023d1d5f2623732619105dc2cfa24 to reduce mocking in the unit test coverage for it. While backporting the bug fix, it was found to be incompatible with earlier versions of Python < 3.6 due to a difference in internal implementation [1]. This reduces the mocking in the unit test to be more agnostic to the internals of the StreamRequestHandler (ancestor of SimpleHTTPRequestHandler) and work across Python versions >= 2.7.

In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:
