ColdFusion 4.0 and 4.5 using IIS 3.0 and 4.0 on Windows NT 4.0 also appear
to be vulnerable.

Work around for IIS 4.0 appears to be identical to for IIS 5.0.  I cannot
determine any sort of fix for IIS 3.0.

The one drawback of the work around is that if you go to any .cfm or .dbm
file that does not exist, you get a standard 404 error from the webserver
rather than the considerably prettier (not that that says much) 404
message that ColdFusion returns.

I'd like to thank Peter Grundl (sorry about the umlaut but I can't figure
out how to do it in my email client) and KPMG for finding this out for us.

Have a great day!  (Or night!)
