Ahh.. so you can basically echo a bunch of ftp commands to a file, run
the ftp client -s:filename.txt to have the box download cmdasp.asp, and
then you can just have that page execute commands?

Nice.

Under IIS4, CMDASP.asp executes in system level context so you are able to
do that (CMDASP.asp has nothing to do with the unicode vuln. itself, we just
use unicode attacks to get script up onto the box). You are right though, a
unicode executed command by itself runs under IUSR context

I thought under UNICODE, you arent able to run such commands as rdisk
and pwdump, because IIS runs as IUSR?

Hi Allen,

If you have UNICODE working, you could upload cmdasp.asp which will let
you execute commands on that server.

If this is NT then what you can do is run "rdisk /s-" to silently update
the repair sam._ file (this is a little trick that I used to use when I
did pen-testing for Deloitte).  Then go to c:\winnt\repair and copy
sam._ to say a public internet folder like c:\inetpub\wwwroot and then
go to your browser and just download the file.
