You can try this kind of things: 1- Run a pwdump through the nc session, 2- Run a rdisk/s to copy the sam to the backup file (c:\winnt\repair\sam._ usually) 3- Schedule an AT command, this will run with Admin privileges (Do steps 1 or 2 , or change a Web File), 4- You can use a program like "leapfrog", that will go to other internal servers (analyze the net with ipconfig /all), try to telnet the internal IP gateway or router, try a net share on others servers (Net Share \\<computername or IP>). 5- Try a command line sniffer that can be uploaded to the web server 6- Try a command line net scan that can be uploaded to the web server (If someone knows a better program, please let me know!) Leap Frog is a TCP/IP program, which will proxy telnet or for that matter any TCP/IP connections from your host through a middle host (Leap Frog) to the desired host. All connections to the destined host will appear to come and be sent to the Leap Frog server. That is the destination server will see no traffic, IP#, mac address, host info or any other info concerning your machine, it will only know about the connecting machine which is running Leap Frog.

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.
