CVE-2019-16114 Information

Description

In ATutor 2.2.4 an unauthenticated attacker can change the application settings and force it to use his crafted database which allows him to gain access to the application. Next he can change the directory that the application uploads files to which allows him to achieve remote code execution. This occurs because install/include/header.php does not restrict certain changes (to db_host db_login db_password and content_dir) within install/include/step5.php.
