Vulnerability Overview

The Masteriyo LMS – eLearning and Online Course Builder for WordPress plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 1.11.4 due to missing validation on the 'course_id' user controlled key. This makes it possible for authenticated attackers, with student-level access and above, to review courses they don't have access to.

Technical Analysis

REMEDIATION: Update to version 1.11.5, or a newer patched version --- IDENTIFIER: CWE-639 (Authorization Bypass Through User-Controlled Key) The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data.
