Php script help

can somebody solve this challenge?

<?php // Welcome to the next step. You will be exploiting the vulnerable in this authentication script. // Hosted here also: https://testurl.com/abc $json = file_get_contents('php://input'); $data = json_decode($json); $password = '14ofQrct98a'; $received_password = $data['password']; if ($password == $received_password && md5($received_password) !== md5($password)) { echo 'Access Granted'; //final request must go to server, it will have a secret response. } else { echo 'Access Denied'; } ?>

If you are a beginner checkout http://bitdegree.org or
https://stackoverflow.com/questions/ask to troubleshoot your code with other developers/coders etc. Best checking the documentation for your script and communicating with the script author or troubleshooting it locally or alternative hosting to make sure it isn’t a limitation of the free plan.
Our team would be more than happy to help you with any problem you encounter. However, we will only provide free support for our system and services. We will help you with basic problems associated with getting scripts running such as advising you of the correct hostname, username, database name and information to us, but if you need help with third-party software, contact the authors of that software or query Google with error message you get.

It is not possible for us to provide help for everyone, fix PHP errors or develop your website as it would require a lot of administrative time. We focus in getting our servers and services up and running.

However, you can upgrade your account at https://www.hostinger.com/special/000webhost and we will provide you with full help in installing your scripts, developing your website and fixing errors.

Thank you
