PHP Run command as sudo without changing any Apache settings


Here is how to run a php script as sudo without changing apache settings.

Save the following snippet as This will act as the receiving script to run commands with sudo permissions.

#!/bin/bash   while :; do     command=$(nc -l 1234)       # "[Sun Apr 21 14:46:34 PDT 2013] ":command""     echo "["$(date)"] \"${command}\""       # Run command received with sudo permissions     sudo -i "${command}"       echo -e "\nreturn code: ${?}" done

Run this script with sudo and keep the script running:

$ sudo bash

Now send a command to be run. Here are two examples to issue commands:

Inside a php script

<?php $data = 'whoami'; // Command to send $fp = stream_socket_client('tcp://'); fwrite($fp, $data); fclose($fp);

On the command line

$ echo "whoami" >/dev/tcp/localhost/1234

Example response:

$ sudo bash [Sun Apr 21 16:16:54 PDT 2013] "whoami" root   return code: 0
