At a glance

This record tracks a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the MoreConvert Wishlist for WooCommerce WordPress plugin, affecting versions <= 1.5.4. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 1.5.5; sites on affected versions should update now. Disclosed April 2023.

Vulnerability Overview

The MC Woocommerce Wishlist plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.5.4. This is due to missing or incorrect nonce validation on several AJAX functions including add_to_cart, add_to_wishlist, load_analytics, change_layout, remove_from_wishlist, delete_item, update_item_quantity, load_fragments. This makes it possible for unauthenticated attackers to modify other user's carts via a forged request granted they can 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, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site.

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

Reaching this weakness in MoreConvert Wishlist for WooCommerce <= 1.5.4 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 MoreConvert Wishlist for WooCommerce the fix is 1.5.5: builds <= 1.5.4 are affected, anything from 1.5.5 onward is not.

Remediation

Update to version 1.5.5, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to MoreConvert Wishlist for WooCommerce: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: MoreConvert Wishlist for WooCommerce 1.5.5 closes this, and updating the plugin is the step that ends it.
