Description

This module exploits a directory traversal vulnerability in ATutor on an Apache/PHP
setup with display_errors set to On, which can be used to allow us to upload a malicious
ZIP file. On the web application, a blacklist verification is performed before extraction,
however it is not sufficient to prevent exploitation.

You are required to login to the target to reach the vulnerability, however this can be
done as a student account and remote registration is enabled by default.

Just in case remote registration isn't enabled, this module uses 2 vulnerabilities
in order to bypass the authentication:

1. confirm.php Authentication Bypass Type Juggling vulnerability
2. password_reminder.php Remote Password Reset TOCTOU vulnerability
