networkmanager - opening a hotspot - wireless security impossible

[8200]

I am using Ubuntu 12.04 amd64 with all latest update.

The bug scenario is the following:
I connect to the internet via. mobile phone network (with the integrated mobile broadband modem) and I
add a wireless connection with the settings
Mode: Ad-hoc
Wireless Security: WPA & WPA2 Personal
IPv4 Settings: Method: Shared to other computers.

I can join this created hotspot from other notebooks and internet is working fine
BUT I can enter ANY PASSWORD and it works.

So there is a major security issue.

Regards,
Arthur

Pictures say more than words attached the settings (of the hotspot server and the client) as screenshots.

This has been broken at the kernel level for a while, see bug 905748.

I'm marking this one as a duplicate.
