You could also utilize the file isapir2s.dll. What you would do is upload that file to the /scripts directory. Then, in your command line through the URL, use isapir2s.dll to execute netcat for your listener: /scripts/isapir2s.dll?(and wherever you put nc.exe) example: /scripts/isapir2s.dll?d:\inetpub\scripts\nc.exe%20-l...etc... The isapir2s.dll is basically a revert to self function, which will make the command you are issue run as context of the web server, SYSTEM. Then, on an IIS4 server, you will have SYSTEM priv. On an IIS 5.0, you may only get IWAM depending on a certain setting within IIS. Hope this may be helpful.

In doing a security assessment - I came across a web server running iis4 that is vulnerable to the unicode exploit. I was able to get it to tftp back to my tftp server and pull down nc and a few other things...then got nc listening with a shell and was able to connect to that shell...I didnt go any further and reported it as it was. I was then questioned on the possibility of it being used to escalate rights to administrator..and asked for a demo... i repeated the above steps, but was unable to stop services and such. I couldnt even delete a file I had uploaded using unicode with tftp. Could someone please point me to info that would explain what i have to do to accomplish this. I have been searching...but apparently not well enough. Again, I hope this gets through..As it has prolly been discussed very much. I apologize in advance for this question.. but im stuck :( Thanks much! t -----BEGIN PGP SIGNATURE----- Version: Hush 2.1 Note: This signature can be verified at https://www.hushtools.com wlwEARECABwFAj0rGdkVHGV3dnR3dmlAaHVzaG1haWwuY29tAAoJEONDjIN5eMWV4yoA n1TdHlIf1vT//ZWzA/D9CaPaVC7bAKCyKMk5UUB8wzny2LtRDKWQNepzFw== =yH9p -----END PGP SIGNATURE----- Communicate in total privacy.
