At a glance

CVE-2024-1128 is a medium-severity Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') vulnerability in the Tutor LMS WordPress plugin, affecting versions <= 2.6.0. It carries a CVSS score of 5.4 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Student level or above. The issue is fixed in version 2.6.1; sites on affected versions should update now. Disclosed February 2024, reported by drop.

Vulnerability Overview

The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to HTML Injection in all versions up to, and including, 2.6.0. This is due to insufficient sanitization of HTML input in the Q&A functionality. This makes it possible for authenticated attackers, with Student access and above, to inject arbitrary HTML onto a site, though it does not allow Cross-Site Scripting

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-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')

The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.

Remediation

Update to version 2.6.1, or a newer patched version

How does WordSec protect against this?

An attacker needs Student access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Tutor LMS 2.6.1 closes this, and updating the plugin is the step that ends it.
