Twisted is an event-based framework for internet applications. Started with
version 0.9.4, when the host header does not match a configured host
twisted.web.vhost.NameVirtualHost
will return a NoResource
resource
which renders the Host header unescaped into the 404 response allowing HTML
and script injection. In practice this should be very difficult to exploit
as being able to modify the Host header of a normal HTTP request implies
that one is already in a privileged position. This issue was fixed in
version 22.10.0rc1. There are no known workarounds.
