Vulnerability Overview

The MasterStudy LMS WordPress Plugin – for Online Courses and Education plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 3.7.41. This is due to insufficient restriction on the capabilities a user may grant themselves. This makes it possible for authenticated attackers, with subscriber-level access and above, to elevate their privileges beyond those intended for their role.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user.

CWE-269: Improper Privilege Management

Reaching this weakness in MasterStudy LMS WordPress Plugin <= 3.7.41 takes an account at Subscriber level or above. Improper privilege management means the code lets an account end up with capabilities its role should not have.

It converts a low-privileged account into an administrative one, which makes every other restriction on the site irrelevant. For MasterStudy LMS WordPress Plugin the fix is 3.7.42: builds <= 3.7.41 are affected, anything from 3.7.42 onward is not.

Remediation

Update to version 3.7.42, or a newer patched version

How does WordSec protect against this?

Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: MasterStudy LMS WordPress Plugin 3.7.42 closes this, and updating the plugin is the step that ends it.
