At a glance

CVE-2022-4016 is a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the Booster Plus for WooCommerce WordPress plugin, affecting versions <= 5.6.5. It carries a CVSS score of 5.4 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 5.6.6; sites on affected versions should update now. Disclosed November 2022, reported by WPScanTeam.

Vulnerability Overview

The Booster plugins (Booster, Booster Plus, and Booster Elite) for WordPress are vulnerable to Cross-Site Request Forgery in versions up to, and including, 5.6.6 (Booster), 5.6.5 (Plus), and 1.1.7 (Elite). This is due to missing or incorrect nonce validation on functions such as 'process_actions' and 'get_delete_all_custom_statuses_button'. This makes it possible for unauthenticated attackers to create and delete arbitrary custom roles 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)

Booster Plus for WooCommerce <= 5.6.5 carries this weakness at process_actions, 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 Booster Plus for WooCommerce the fix is 5.6.6: builds <= 5.6.5 are affected, anything from 5.6.6 onward is not.

Remediation

Update to version 5.6.6, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Booster Plus for WooCommerce: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Booster Plus for WooCommerce 5.6.6 closes this, and updating the plugin is the step that ends it.
