CVE-2019-16114
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.78%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
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.
