DESCRIPTION:
Urmas Kahar and Tarmo Kaljumae have reported a security issue in
Proxim Wireless Access Points products, which can be exploited by
malicious people to bypass certain security restrictions.

The problem is caused due to the presence of a static WEP key set to
"12345". This can be exploited to bypass the 802.1x authentication
and gain access to network resources.

Successful exploitation requires that the access point has 802.1x
enabled and WEP disabled.
