ATutor 2.2.4 allows Arbitrary File Upload and Directory Traversal, resulting in remote code execution via a ".." pathname in a ZIP archive to the mods/_core/languages/language_import.php (aka Import New Language) or mods/_standard/patcher/index_admin.php (aka Patcher) component.

An issue was discovered in ATutor through 2.2.4. It allows the user to run commands on the server with the teacher user privilege. The Upload Files section in the File Manager field contains an arbitrary file upload vulnerability via upload.php. The $IllegalExtensions value only lists lowercase (and thus .phP is a bypass), and omits .shtml and .phtml.

Multiple cross-site request forgery (CSRF) vulnerabilities in ATutor 2.2 allow remote attackers to hijack the authentication of administrators for requests that (1) create an administrator account via a request to mods/_core/users/admins/create.php or (2) create a user account via a request to mods/_core/users/create_user.php.

confirm.php in ATutor 2.2 and earlier allows remote attackers to bypass authentication and gain access as an existing user via the auto_login parameter.
