At a glance

CVE-2024-4352 is a high-severity Missing Authorization vulnerability in the Tutor LMS Pro WordPress plugin, affecting versions <= 2.7.0. It carries a CVSS score of 8.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). The root cause is a missing authorization check on a reachable function. The issue is fixed in version 2.7.1; sites on affected versions should update now. Disclosed May 2024, reported by villu164.

Vulnerability Overview

The Tutor LMS Pro plugin for WordPress is vulnerable to unauthorized access of data, modification of data, loss of data due to a missing capability check on the 'get_calendar_materials' function. The plugin is also vulnerable to SQL Injection via the ‘year’ parameter of that function 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 subscriber-level permissions and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

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 confidentiality, integrity, availability — full site compromise territory.

CWE-862: Missing Authorization

Tutor LMS Pro <= 2.7.0 carries this weakness at get_calendar_materials, and reaching it takes a caller who can reach the endpoint. 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 2.7.1: builds <= 2.7.0 are affected, anything from 2.7.1 onward is not.

Remediation

Update to version 2.7.1, 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 2.7.1 closes this, and updating the plugin is the step that ends it.
