Parse POST parameter to PHP file using CLI












0














The content of my file:



$ cat z-cmd.php 
<?php system($_POST['z']); ?>


What I tried:



$ QUERY_STRING='z=touch plm' php-cgi z-cmd.php 
X-Powered-By: PHP/5.6.36
Content-type: text/html; charset=UTF-8

<br />
<b>Warning</b>: system(): Cannot execute a blank command in <b>/home/jeremy/z-cmd.php</b> on line <b>3</b><br />


How can I run commands using the z POST parametter?

          Use $argv array, its defined by default. $_POST can't be used in cli php application.



          For the z-cmd.php should be like (Note that $argv[0] contain the file name itself 'z-cmd.php'):



          <?php system($argv[1]); ?>


          and for the command you could use one of the below



          $ php-cgi z-cmd.php 'touch plm'
          $ QUERY_STRING='touch plm' | php-cgi z-cmd.php $QUERY_STRING
