At a glance

CVE-2023-37873 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the WooCommerce Ship to Multiple Addresses WordPress plugin, affecting versions <= 3.8.5. It carries a CVSS score of 4.4 (reachable over the network). The issue is fixed in version 3.8.6; sites on affected versions should update now. Disclosed July 2023, reported by Rafie Muhammad.

Vulnerability Overview

The WooCommerce Ship to Multiple Addresses plugin for WordPress is vulnerable to Reflected Cross-Site Scripting in versions up to, and including, 3.8.5 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.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, and no interaction from a victim user.

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

Reaching this weakness in WooCommerce Ship to Multiple Addresses <= 3.8.5 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 WooCommerce Ship to Multiple Addresses the fix is 3.8.6: builds <= 3.8.5 are affected, anything from 3.8.6 onward is not.

Remediation

Update to version 3.8.6, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to WooCommerce Ship to Multiple Addresses: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: WooCommerce Ship to Multiple Addresses 3.8.6 closes this, and updating the plugin is the step that ends it.
