OK, that was a bit too optimistic. I found couple of cases where this
vulnerability can be triggered over EAP, so no public availability for
the test tool for now. Feel free to contact me privately if you have a
justifiable use for such a test tool. I'll probably push it to
eapol_test later once there has been some more time to get
authentication servers updated.
