The novnc, serial, and spice console proxies are implemented as websockify servers and the request handler inherits from the python standard SimpleHTTPRequestHandler. There is a known issue 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. The novnc, serial, and spice console proxies will now reject requests that pass a redirection URL beginning with "//" with a 400 Bad Request. (https://bugs.launchpad.net/nova/+bug/1927677) (https://bugs.python.org/issue32084) Bug Fixes ********* * Addressed an issue that prevented instances with 1 vcpu using multiqueue feature from being created successfully when their vif_type is TAP.
