Thanks Leo, that is good info.
I've already nofified the customer of the risk that reading a file, could cause
a information leakage to a unauthorized user.
Testing has also reviled that no audit trail is created, even when NTFS
Auditing for the file is configured, <----- Nice no way to track access
I've been continueing the test, to discover how much information I can
compromise.

Personally I'd take a slightly different route than trying to see if you
can use the vulnerability to upload a file.
1) Can you execute programs like cmd.exe with this vulnerability?
2) Can you grab the backup SAM file?
If I found a system that allowed either of these I'd stop testing and
notify the project customer immediately. If either of those methods are
allowed then it should be evidence enough that you could take control of
the system if you wished to spend enough time on it. Proving the severe
vulnerability and moving on shows to the client that you are wasting
their time by playing around.
If you really do wish to upload a file to the server then I'd check to
see if you can execute cmd.exe and use it to search for files like
upload.asp or even wget or ftp. There are also likely tools (I just
don't know of any off the top of my head) that will allow you to open a
reverse shell using cmd.exe on the target host.
Please keep us updated with what you find and whether or not this is a
custom web app or one that others might also see in their testing.

Hello everyone, I'm in the middle of a test on a app that the following
command works on
http://mycomputer:port#/..//..//..//..//..//..//..//windows/win.ini
and it will prompt me to save the file, if i check my packet capture I
see the contents of the file.
So far I've been unable to get a put or post command to work and was
hoping to get some ideas from you all on things to try.
I've been trying to get nc/telnet and some other tools to help me with
the put comand
Thanks in advance --John
