School Management <= 91.5.0 - Unauthenticated Arbitrary File Upload

The School Management System for Wordpress plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the mj_smgt_user_avatar_image_upload() function in all versions up to, and including, 91.5.0. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible.

School Management System for Wordpress <= 93.0.0 - Authenticated (Student+) Account Takeover and Privilege Escalation

The School Management System for Wordpress plugin for WordPress is vulnerable to privilege escalation via account takeover in all versions up to, and including, 93.0.0. This is due to the plugin not properly validating a user's identity prior to updating their details like email and password through the mj_smgt_update_user() and mj_smgt_add_admission() functions, along with a local file inclusion vulnerability. This makes it possible for authenticated attackers, with student-level access and above, to change arbitrary user's email addresses and passwords, including administrators, and leverage that to gain access to their account. This was escalated four months ago after no response to our initial outreach, yet it still vulnerable.

School Management System for Wordpress <= 92.0.0 - Authenticated (Student+) SQL Injection via 'view-attendance'

The School Management System for Wordpress plugin for WordPress is vulnerable to SQL Injection via the 'view-attendance' page in all versions up to, and including, 92.0.0 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query in the mj_smgt_view_student_attendance() function. This makes it possible for authenticated attackers, with Student-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

School Management System for Wordpress <= 93.0.0 - Missing Authorization to Unauthenticated Arbitrary Post Deletion

The School Management System for Wordpress plugin for WordPress is vulnerable to unauthorized loss of data due to a missing capability check on the 'mj_smgt_remove_feetype' and 'mj_smgt_remove_category_new' AJAX actions in all versions up to, and including, 93.0.0. This makes it possible for unauthenticated attackers to delete arbitrary posts.

School Management System for Wordpress <= 93.0.0 - Reflected Cross-Site Scripting

The School Management System for Wordpress plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'title' parameter in all versions up to, and including, 93.0.0 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

School Management <= 91.5.0 - Authenticated (Student+) Arbitrary File Upload

The School Management System for Wordpress plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the mj_smgt_load_documets_new() and mj_smgt_load_documets() functions in all versions up to, and including, 91.5.0. This makes it possible for authenticated attackers, with Student-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible.

School Management System for Wordpress <= 92.0.0 - Authenticated (Subscriber+) SQL Injection via 'mj_smgt_show_event_task'

The School Management System for Wordpress plugin for WordPress is vulnerable to SQL Injection via the 'id' parameter of the 'mj_smgt_show_event_task' AJAX action in all versions up to, and including, 92.0.0 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with Custom-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

Mojoomla School Management System for WordPress allows SQL Injection via the id parameter.
