At a glance

CVE-2022-4710 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the Royal Addons for Elementor WordPress plugin, affecting versions <= 1.3.59. 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 1.3.60; sites on affected versions should update now. Disclosed January 2023, reported by Ram.

Vulnerability Overview

The Royal Elementor Addons plugin for WordPress is vulnerable to Reflected Cross-Site Scripting in versions up to, and including, 1.3.59, due to due to insufficient input sanitization and output escaping of the 'wpr_ajax_search_link_target' parameter in the 'data_fetch' function. 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. This is occurring because 'sanitize_text_field' is insufficient to prevent attribute-based 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 privileges on the target site.

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

Royal Addons for Elementor <= 1.3.59 carries this weakness at wpr_ajax_search_link_target, 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 Royal Addons for Elementor the fix is 1.3.60: builds <= 1.3.59 are affected, anything from 1.3.60 onward is not.

Remediation

Update to version 1.3.60, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Royal Addons for Elementor: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Royal Addons for Elementor 1.3.60 closes this, and updating the plugin is the step that ends it.
