Tutor LMS < 2.3.0 – Subscriber+ Stored Cross-Site Scripting | CVE 2023-4805 | Plugin Vulnerabilities

Description

The plugin does not sanitise and escape some of its settings, which could allow users such as subscriber to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup)

Proof of Concept

1. Register a student account and go to the "Dashboard" plugin (https://example.com/dashboard/settings/)
2. Add the payload `&lt;svg/onload=alert(origin)&gt;` to either the "First Name" or "Last Name" fields.
3. Click on "Update Profile" and reload the page.
4. When you do that, you will see the XSS.

Affects Plugins

Fixed in 2.3.0
