At a glance

CVE-2024-4351 is a high-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') 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 'authenticate' function in all versions up to, and including, 2.7.0. This makes it possible for authenticated attackers, with subscriber-level permissions and above, to gain control of an existing administrator account.

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-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

Tutor LMS Pro <= 2.7.0 carries this weakness at authenticate, and reaching it takes a caller who can reach the endpoint. SQL injection happens when request data is concatenated into a query instead of being bound as a parameter, letting an attacker change the structure of the statement rather than just its values.

A working injection can read any table the database user can see, which on a WordPress install means user records, password hashes and session or API secrets stored in options. 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?

The attempt arrives as an ordinary request to Tutor LMS Pro: WordSec's web application firewall inspects request payloads before WordPress loads them. 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.
