At a glance

This record tracks a high-severity Cross-Site Request Forgery (CSRF) vulnerability in the Trust Payments Gateway for WooCommerce (JavaScript Library) WordPress plugin, affecting versions <= 1.2.0. 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 1.2.1; sites on affected versions should update now. Disclosed July 2022.

Vulnerability Overview

The Trust Payments Gateway (3DS2) plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.2.0. This is due to missing nonce validation on the tpgw_refund_purchase() function. This makes it possible for unauthenticated attackers to refund order purchases 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)

Trust Payments Gateway for WooCommerce (JavaScript Library) <= 1.2.0 carries this weakness at tpgw_refund_purchase(), 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 Trust Payments Gateway for WooCommerce (JavaScript Library) the fix is 1.2.1: builds <= 1.2.0 are affected, anything from 1.2.1 onward is not.

Remediation

Update to version 1.2.1, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Trust Payments Gateway for WooCommerce (JavaScript Library): WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Trust Payments Gateway for WooCommerce (JavaScript Library) 1.2.1 closes this, and updating the plugin is the step that ends it.
