I don't seem to have the same file directory as that posted in the second
link. Instead I have:

\CFIDE\scripts\ajax\FCKeditor\editor\filemanager\upload\cfm\config.cfm

and:

\CFIDE\scripts\ajax\FCKeditor\editor\filemanager\browser\default\connectors\
cfm\config.cfm

Both of these files look like they are encrypted.

Am I missing something?

Site down, probably load.
In summary:
CF8.0.1 ships with a plugin in the FCKeditor that powers rich text editing in
a non-default, insecure state.
Find config.cfm
in ....../CFIDE/scripts/ajax/FCKeditor/editor/filemanager/connectors/cfm and
change 'Config.enabled' to false at the top.

Then review if you need any of the features you just turned off and take it
from there.

How does this exploit actually work?  I presume it is somebody directly
accessing the exposed, vulnerable, exploitable files via
www.yourSite.org/cfide/scripts/something?  Is that correct?  If so, we
may have been lucky enough that our cfide folder is not publicly
available at the moment, but I would like to know more as I present this
up the chain to get remediation steps done on our production servers.

The recommendation seems to be to install the latest version of
fckeditor independently of the built in ColdFusion edition and to make
sure that it resides and works within properly sandboxed portions of you
system so that permission escalation is much harder to accomplish.

Yes, I'm pretty certain that's how it works. You may want to test the actual CF URLs even if you've moved CFIDE, as CF has a defined URL pattern match in its configuration to ensure that some URLs work in any case.

You should take the same precautions you would with any file upload. Don't allow uploads to web-accessible directories that allow code execution on the server. Better yet, don't allow uploads to web-accessible directories at all, so that your server can't unwittingly host client-side malware. Don't run CF with root credentials, so that successfully uploaded CF scripts can't do bad things to your system.

Well, that was my subtle request for a good URL or two to test!! :-)

I tried one or two I could guess by looking at the directory under
scrutiny and I got an encouraging 404 Not Found for them.  But I realize
I may not be using the best URL's for my testing.

Dave (or anyone else with information),

I know the vulnerability was in older versions of FCKEditor...if one were to
install and use the current version, does it still have the vulnerability or
has that been fixed?  I just got an emergency gig to fix a site that was
hacked because of this and we need to know if it is safe to do this or just
keep FCKEditor disabled inthe meantime.

Supposedly on July 6 a new version will be released that is at least
better, if not 'fixed'.

Kind of glad I put mine behind logins from the get-go.  I am guessing
that this affects all FCKEditor installations and not just CF8's
cftextarea.

Way back when, an earlier cf connector was so full of holes I wound up
rewriting it with another developer's help and posting it on their
forum.  Guess that since then its code got a lot more complex but not
a lot better.
