CFCookie vs CFHeader for Session Cookies

2011-05-22T12:07:00.000+05:30

A lot of times we re-write ColdFusion session cookies to add some additional flags. Flags like Secure, HttpOnly which were not present in the earlier releases. HttpOnly support was added in ColdFusion 9.0.1.

When one doesn't use J2EE session management, ColdFusion managed sessions are used. In This two cookies, CFID and CFTOKEN are set. There are additional authentication cookies added when is used. By default till CF9.0 they were not marked as secure and HttpOnly. With CF9.0.1, support for HttpOnly was added.

Today, I am going to talk about, how to set these additional flags on these cookies. This is talked about a lot of times, but I would like to add my 2 cents to this. To add these additional flags (these flags provide additional security), one can use CFCookie or CFHeader. And here is the difference which I thought was worth mentioning.

With, CFCookie, the cookie name is always converted to Upper Case, and Value is encoded. This is not a problem for CFID or CFTOKEN but might not work with Authorization cookie, or even if you want to set some flags for JSessionID cookie.

CFHeader on the other hand will be handy to set any of these flags. So the preferred choice should be CFHeader while doing this.

For setting these cookie at your own, you must set sessionmanagement = true, clientclientcookie = false in Application.cfc/cfm as appropriate. Here is an example of an application with application name "test"

Using CFCookie

<cfif NOT StructKeyExists( cookie,"CFID" ) OR ( cookie.CFID NEQ session.CFID )>


<cfcookie name="CFID" value="#session.CFID#" secure="true" httponly="true">

<cfcookie name="CFTOKEN" value="#session.CFTOKEN#" secure="true" httponly="true">
</cfif>

<cfcookie name="CFAUTHORIZATION_test" value="#cookie.CFAUTHORIZATION_test#" secure="true">

Note: cfccokie tag for Authorization cookie, here will create another cookie with same name but in different case, rather than updating the original one.

Using CFHeader

<cfif NOT StructKeyExists( cookie,"CFID" ) OR ( cookie.CFID NEQ session.CFID )>

</cfif>

Hope this was helpful.

Update on Security Hot-Fix Feb 2011

2011-03-08T13:50:00.000+05:30

There is an update on Security Hot-Fix released in Feb 2011.

List of issues addressed are as follows:

Session is lost for an application accessed within same domain *.
Formatting problem for ResponseTime table on debug template.
A minor fix for CFIDE/wizards/common/_logintowizard.cfm

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.

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. This happened as the cookie was overwritten by later application when accessed in same browser.

With the current update to the patch, all above problems are fixed. ColdFusion will still accept such tokens but after validations.

In case someone still wants to completely swtich off the fix for Session Fixation issue they can add the following JVM property –Dcoldfusion.session.protectfixation=false in the JVM Arguments for the Coldfusion Server.

Latest hotfixes containing the fixes for the above issues are updated in the technote. Instructions to apply the hotfix remain same. All the users should re-apply the hotfixes if they have applied it already. Security Bulletin can be found here.

Security Hot-Fix update for ColdFusion and Session

2011-02-10T15:43:00.000+05:30

With the recent Security Hot-Fix for ColdFusion, an important vulnerability is fixed - Session Fixation.

Previous behavior with out the Hot-Fix - One can create a ColdFusion session with self provided CFID and CFTOKEN and then mail a victim customer a URL with those tokens. Now both of them can use same session.

Earlier if one has two different Applications in sub directories for both the applications Session tokens for ColdFusion Session used to be same thus both Applications will work fine with in the same browser.

Now after applying the hot-fix, If user wants to support such different Applications with sub directories, they can set session Cookies with Domain and path.

Example:

For second application in sub Directory do this in OnSessionStart -

<cfcookie name="CFID" value="SESSION.CFID" path="/subdir">

<cfcookie name="CFTOKEN" value="SESSION.CFTOKEN" path="/subdir">

Hope this was helpful.

Duplicate flex session error in Server Manager and MultiServer Monitor while registering instances running on same machine

2010-08-03T16:03:00.001+05:30

In Server Manager AIR application or MultiServer Monitor, when you register two or more ColdFusion server instances running on the same machine with same hostname, you might experience issues while fetching the settings from the server resulting in DuplicateSessionException on the server.

The Workaround is to register different aliases to the same IP in the hosts file

and associating each alias with one CF server instance when there are multiple instances running.
Eg: In the machine where Server Manager AIR application (or the MultiServer Monitor) is running, add the multiple hostnames to the servers
Say on the machine 10.101.25.22 , 3 ColdFusion instances are running and on the machine where Server Manager AIR application (say 10.28.272.28) add as follows in the hosts file
   10.101.25.22 prod-1
   10.101.25.22 prod-2
   10.101.25.22 prod-3
And while registering the CF server instances use prod-1 for one instance, prod-2 for second instance & prod-3 for 3rd instance as host names.
This resolves the issue.

Vinu Kumar is one of the ColdFusion engineers. He has written a demo application explaining how to deploy ColdFusion in JBoss and about developing ColdFusion applications with Java. His sample application, a travel website, demonstrates how to rewrite your JSP to CFML pages and access Java code from your CFML pages. It also shows you how to write portlets for the JBoss portal and embed the sample application in the portal.

He's got a new article on the Adobe Developer Center about it. Check it out.

ColdFusion Session cookies & HttpOnly

2010-07-28T21:28:00.000+05:30

With ColdFusion 901 release now ColdFusion Session Cookies can be marked HttpOnly. This reduces the chance of session information being compromised on Cross Site Scripting (XSS) attack.
To mark these session Cookies (CFID, CFTOKEN, jsessionid HttpOnly), add the following jvm property -

coldfusion.sessioncookie.httponly=true

Currently there is a limitation on JBoss/Tomcat for marking jsessionid cookie as httponly.

Any other ColdFusion cookies can be marked as HttpOnly by using "httponly" attriibute of cfcookie tag.
