Subject: ColdFusion File Upload Exploit

The following message was posted to the Allaire's COLD FUSION forums:

By default, on Windows NT installations, the CF function, GetTempDirectory
returns C:\WINNT.

Not quite true (from the API docs):

The GetTempPath function gets the temporary file path as follows:

1. The path specified by the TMP environment variable.
2. The path specified by the TEMP environment variable, if TMP is not
defined.
3. The current directory, if both TMP and TEMP are not defined.

Although this is correct, apparently Cold Fusion does more than wrap the
Win32 API in their internal API, so I'm in error - it works the way they
said (which IMHO, seems not to be too smart - if you're going to hard code
a default, %systemroot% isn't a good one).

WORKAROUND: Currently, TEMP is correctly set to C:\TEMP as a User
Environment
Variable, but should also be set as a System Environment Variable.

I agree with this.

Oh - and as was just pointed out on NTBUGTRAQ, you have to restart any apps
which you'd like to take advantage of any new environment variables.
