Hi

I recently got aware of a possible phishing attack using the service
redirect, whereas it is described in detail at

http://palizine.plynt.com/issues/2011Sep/sso-flaws/

The solution seems to be rather simple, that one has to register the
services inside CAS, in order to prevent
redirects to mailicious URLs.

Thinking about it some more I thought it might be best to enforce the
registration, which means by default
only redirects are being executed for services which are registered. The
configuration could be in a such a way,
that one could still alllow any service URLs, but one would have to
configure this explicitely and hence would be aware of the risk explicitely.

WDYT?

Thanks

Michael
