At a glance

CVE-2024-3190 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the Unlimited Elements For Elementor WordPress plugin, affecting versions <= 1.5.107. It carries a CVSS score of 5.4 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Contributor level or above. The issue is fixed in version 1.5.108; sites on affected versions should update now. Disclosed May 2024, reported by Tim Coen.

Vulnerability Overview

The Unlimited Elements For Elementor (Free Widgets, Addons, Templates) plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's text field widget in all versions up to, and including, 1.5.107 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Please note that this vulnerability is different in that the issue stems from an external template. It appears that older version may also be patched due to this, however, we are choosing 1.5.108 as the patched version since that is the most recent version containing as known patch.

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

Reaching this weakness in Unlimited Elements For Elementor <= 1.5.107 takes an account at Contributor level or above. 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 Unlimited Elements For Elementor the fix is 1.5.108: builds <= 1.5.107 are affected, anything from 1.5.108 onward is not.

Remediation

Update to version 1.5.108, or a newer patched version

How does WordSec protect against this?

An attacker needs Contributor 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: Unlimited Elements For Elementor 1.5.108 closes this, and updating the plugin is the step that ends it.
