At a glance

This record tracks a high-severity Cross-Site Request Forgery (CSRF) vulnerability in the Products Quick View for WooCommerce WordPress plugin, affecting versions <= 2.0.1. It carries a CVSS score of 8.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 2.0.2; sites on affected versions should update now. Disclosed November 2022.

Vulnerability Overview

The following plugins for WordPress are vulnerable to Cross-Site Request Forgery: a3 Lazy Load (<= 2.6.0), Contact Us Page – Contact People (<= 3.6.1), a3 Portfolio (<= 3.0.1), Dynamic Product Gallery for WooCommerce (3.0.1), a3 Responsive Slider (<= 2.2.0), Compare Products for WooCommerce (<= 2.8.2), Products Quick View for WooCommerce (<= 2.0.1), Product Sort and Display for WooCommerce (<= 2.2.2), Product Widget Slider for WooCommerce (), WP Email Template (<= 2.6.2). This is due to missing nonce validation on the reset_settings() function. This makes it possible for unauthenticated attackers to reset the plugin's settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

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. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-352: Cross-Site Request Forgery (CSRF)

Products Quick View for WooCommerce <= 2.0.1 carries this weakness at reset_settings(), and reaching it takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.

An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. For Products Quick View for WooCommerce the fix is 2.0.2: builds <= 2.0.1 are affected, anything from 2.0.2 onward is not.

Remediation

Update to version 2.0.2, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Products Quick View for WooCommerce: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Products Quick View for WooCommerce 2.0.2 closes this, and updating the plugin is the step that ends it.
