Vulnerability Overview

The tutor_quiz_builder_get_question_form AJAX action from the Tutor LMS – eLearning and online course solution WordPress plugin before 1.8.3 was vulnerable to UNION based SQL injection that could be exploited by students.

Technical Analysis

REMEDIATION: Update to version 1.8.3, or a newer patched version --- IDENTIFIER: CWE-89 (Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')) The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
