Setting session-only cookies is a known good practice and to do this in CF you have to turn off the default cookie management and set your own (unless you use JSessions of course, but we and I'm sure many others don't).We are installing CF10 Enterprise on Windows 2008 RC2 with IIS 7.

I think it would be good if Adobe could document this in some way as it's sure to catch quite a few of your customers out. I'll confirm definitively once we're sure. But if you've had your browser open for a while and are logging in for the second time, then the old cookie would have been used with the wrong session ID. It explains the intermittence: if you opened your browser and logged in you wouldn't have had any problem because the cookie would be new. Testing locally has certainly confirmed it. But I'm pretty confident this is the solution.

Shilpi, we've only switched on the protection again in the last hour having had to go through all our code base first, and being Friday there aren't so many people at work to verify. I've written a tiny app which demonstrates the changed behaviour: I'll try and write it up as a blog post later on. Is it absolutely necessary to fix the Fixation vulnerability? This seems to be a critical change of behaviour that is clearly breaking apps. So with the HotFix applied, if CFID/CFTOKEN cookies exist in the browser, the conditional will, as you say, prevent the new session keys being written, and the session will be lost on the next request. With this HotFix, it seems that ColdFusion will create new CFID/CFTOKEN values to link up a new session REGARDLESS of whether any cookies already exist. This meant that it was not necessary to write new cookies if they already existed, hence the conditional widely used when manually setting session cookies. If it found cookies from an expired session, then it would use them for the new session. Prior to the HotFix, when starting a new session ColdFusion would only create new CFID/CFTOKEN values if none already existed in the browser's cookies. Shilpi, I think I've identified the problem from what you say. All the users should re-apply the hotfixes if they have applied it already. Instructions to apply the hotfix remain same. Latest hotfixes containing the fixes for the above issues are updated in the technote. In case someone still wants to completely swtich off the fix for Session Fixation issue they can add the following JVM property –=false in the JVM Arguments for the Coldfusion Server.

ColdFusion will still accept such tokens but after validations.

With the current update to the patch, all above problems are fixed. This happened as the cookie was overwritten by later application when accessed in same browser. In ColdFusion's affected versions,any given CFID/CFTOKEN values of ColdFusion Session identifiers was used to create a new session. After the fix for the same, Applications being accessed with in same domain and having client cookie based session Management enabled started mis-functioning.

With Session Fixation vulnerability attacker fixate (set) another person's session identifier (SID) and, once the user authenticates, the attacker has access to the authenticated session.
