Pavel, What do you mean "control CAS"? And yes HTTPS all the way! Tom On Feb 18, 2011, at 8:53 AM, Pavel Tavoda wrote:
Problem is between your browser -> NT domain server and your browser -> CAS server. Not between your browser -> other side authenticated with CAS ticket. If you can control CAS I guess you aren't vulnerable to this. And of course I hope you use HTTPS between your browser and CAS.

I have read the wikipedia article http://en.wikipedia.org/wiki/NTLM#Vulnerabilities But don't see how its a problem with a properly secured network. Does anyone else have some data I can use to understand how the user or the network might be vulnerable?
