At a glance

CVE-2024-10633 is a high-severity Improper Neutralization of Directives in Dynamically Evaluated Code ('Eval Injection') vulnerability in the Quiz Maker Developer WordPress plugin, affecting versions 20.0.0 – 21.8.0. It carries a CVSS score of 7.3 (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 arbitrary shortcode execution 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). This is due to the software allowing users to execute an action that does not properly validate a value before running do_shortcode. This makes it possible for unauthenticated attackers to execute arbitrary shortcodes. 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, and no interaction from a victim user.

CWE-95: Improper Neutralization of Directives in Dynamically Evaluated Code ('Eval Injection')

The product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes code syntax before using the input in a dynamic evaluation call (e.g. eval).

Remediation

Update to version 21.8.0.100, or a newer patched version

How does WordSec protect against this?

Requests carrying this pattern arrive without a session, so nothing upstream of the firewall gets a chance to reject them: WordSec's web application firewall inspects request payloads before WordPress loads them. Classes like this one can leave something behind, so the staged malware scanner is the second half: it looks for dropped files and modified code rather than for the request that created 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.
