At a glance

This record tracks a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the Zorem Local Pickup for WooCommerce WordPress plugin, affecting versions <= 1.5.2.

The issue is fixed in version 1.5.3; sites on affected versions should update now. Disclosed March 2023.

Vulnerability Overview

The Advanced Local Pickup for WooCommerce for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.5.2. This is due to missing or incorrect nonce validation on the functions wclp_update_state_dropdown_fun, wclp_update_work_hours_list_fun, wclp_update_edit_location_form_fun, and wclp_apply_work_hours_fun. This makes it possible for unauthenticated attackers to invoke those functions resulting in plugin settings changes 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.

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

Reaching this weakness in Zorem Local Pickup for WooCommerce <= 1.5.2 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 Zorem Local Pickup for WooCommerce the fix is 1.5.3: builds <= 1.5.2 are affected, anything from 1.5.3 onward is not.

Remediation

Update to version 1.5.3, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Zorem Local Pickup for WooCommerce: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Zorem Local Pickup for WooCommerce 1.5.3 closes this, and updating the plugin is the step that ends it.
