At a glance

CVE-2024-5784 is a high-severity Missing Authorization vulnerability in the Tutor LMS Pro WordPress plugin, affecting versions <= 2.7.2. It carries a CVSS score of 7.1 (reachable over the network; low attack complexity; high integrity impact). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 2.7.3; sites on affected versions should update now. Disclosed August 2024, reported by Thanh Nam Tran.

Vulnerability Overview

The Tutor LMS Pro plugin for WordPress is vulnerable to unauthorized administrative actions execution due to a missing capability checks on multiple functions like treport_quiz_atttempt_delete and tutor_gc_class_action in all versions up to, and including, 2.7.2. This makes it possible for authenticated attackers, with the subscriber-level access and above, to preform an administrative actions on the site, like comments, posts or users deletion, viewing notifications, etc.

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. A successful exploit has high impact on integrity.

CWE-862: Missing Authorization

Reaching this weakness in Tutor LMS Pro <= 2.7.2 takes an account at Subscriber level or above. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.

Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. For Tutor LMS Pro the fix is 2.7.3: builds <= 2.7.2 are affected, anything from 2.7.3 onward is not.

Remediation

Update to version 2.7.3, 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: Tutor LMS Pro 2.7.3 closes this, and updating the plugin is the step that ends it.
