Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in Themeum Tutor LMS.This issue affects Tutor LMS: from n/a through 2.7.1.
The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 2.7.1 via the 'attempt_delete' function due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with Instructor-level access and above, to delete arbitrary quiz attempts.
The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to time-based SQL Injection via the ‘course_id’ parameter in all versions up to, and including, 2.7.1 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 admin access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
