At a glance

CVE-2024-10636 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the Quiz Maker Developer WordPress plugin, affecting versions 20.0.0 – 21.8.0. It carries a CVSS score of 6.1 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 21.8.0.100; sites on affected versions should update now. Disclosed January 2025, reported by abrahack.

Vulnerability Overview

The Quiz Maker Business, Developer, and Agency plugins for WordPress is vulnerable to Reflected Cross-Site Scripting via the ‘content’ parameter in all versions up to, and including, 8.8.0 (Business), up to, and including, 21.8.0 (Developer), and up to, and including, 31.8.0 (Agency) due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. NOTE: The three variations of this software (Business, Developer, and Agency) share the same plugin slug, so you may get an alert even if you are running the latest version of any of the pieces of software. In these cases it is safe to dismiss the notice once you've confirmed your site is on a patched version of the applicable software.

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 privileges on the target site.

CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Quiz Maker Developer 20.0.0 – 21.8.0 carries this weakness at content, and reaching it takes a caller who can reach the endpoint. Cross-site scripting happens when input from a request is written into a page without being escaped for the context it lands in, so the browser parses attacker-supplied text as markup or script.

Injected script runs with the privileges of whoever views the affected page, which is how these flaws turn into administrator session theft, silent account creation or persistent backdoors in page content. For Quiz Maker Developer the fix is 21.8.0.100: builds 20.0.0 – 21.8.0 are affected, anything from 21.8.0.100 onward is not.

Remediation

Update to version 21.8.0.100, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Quiz Maker Developer: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Quiz Maker Developer 21.8.0.100 closes this, and updating the plugin is the step that ends it.
