FCKeditor Access Denied

October 15, 2009

I have a client using the standalone FCKEditor on his server (not the one in /CFIDE/ it is located at /FCKeditor/), but after installing the security hotfix for ColdFusion 8's builtin FCKeditor, the file manager for uploading and inserting images stopped working. He was getting a JRun Servlet Error: 403 Access denied.

It turns out that hotfix (hf801-77218) will actually block any CFM request matching /fckeditor/editor/filemanager/ anywhere in the URI.

To bypass this feature you need to add the JVM argument: -Dcoldfusion.fckupload=true to your JVM arguments. This is found in the ColdFusion administrator under Java & JVM settings on Standard, or in the jvm.config file on Enterprise.

In general I think this is a good feature, though it probably will cause an issue with anyone who uses FCKeditor as outside of cftextarea.

Make sure when you enable FCKeditor's file connector that you do so in a secure manner. For example, don't just set config.enabled = true do something like this:

config.enabled = IsDefined("session.isAdminUser") AND session.isAdminUser;

This is probably not an issue if you've upgraded to CKEditor. Not sure if it still uses the same url structure as the obsolete FCKEditor...

If you are on shared hosting and cannot change any server setting or get the hosting company to do it, you can just rename the directory where FCKEditor is located. I changed mine to just editor, then in fckeditor.js changed the this.basepath variable to /editor/. You also have to change all of the calls to the editor if you call it as a custom tag. If you use the CFC, you have to change the this.basepath variable there as well.

Huh. It seems like I avoided this problem by putting my stand-alone version of FCK into a different directory off my wwwroot. So instead the URI for fck reads "/[other dir]/fckeditor/editor/filemanager/".

Tho it will soon be moot since I'll be upgrading to CKeditor just as Brian mentioned.

@Doug - The CF8 hotfix will still block /whatever/fckeditor/editor/filemanager/anything.cfm maybe you didn't apply the hotfix jar, and just updated the /CFIDE folder.

Hey Pete, turns out you were right. I fixed the problem just by removing the /filemanager subdirectory. The problem came back to bite me when I installed CF9 however, but your solution worked in CF9 too. Thanks!

(Tho I guess it means I must go into CF9's CFIDE and manually fix it again. Oh well. )

Pete, this post has beeen very usefull for me; i add that cf9 last release has a new built in function named fileUpload(), just as a function in fckeditor connectors/cfm/commands.cfm, included by cf_connector.cfm, so we have to change this function name, ie file_upload(). regards

@salvatore thanks for posting that, I'm sure others will find that useful too.

I recently began supporting a ColdFusion application that is still using FCKeditor but unfortunately it stopped working when we upgraded to CF9. I ended up on this post when I ran into the 403 error mentioned above. I set -D in the admin panel and everything started working again because we were using config.enabled. I am trying to access session data but I cannot and I am using the standard FCKEditor that comes packaged with CF9. Any thoughts on securely enabling the FCKEditor upload?

In my config files I am doing:

if (IsDefined("Session.MM_Username") AND Session.MM_Username NEQ "") { config.enabled = true; } else { config.enabled = false; }

and I constantly get the disabled message, which is probably correct because I am probably not accessing the actual session information that I want.

In the Application.cfc the out of the box verificyClient() was not working so I had to remove it and thinking I could enable session variables I included:

But everything is still disabled.

*Correction: ..."n because we were using config.enabled" I mean't config.enabled = true, which I am now trying to secure but can't because I am losing access to the right session data *I think*

Pete, Fantastic info, worked a treat! I searched for ages with searches like 'CfmServlet.accessDenied' and 'XML request error: Internal Server Error (500)' as these were in the error message returned but got no decent info. One request to you resolved it. Thanks.
