Vulnerability Overview

The Eupago Gateway For Woocommerce plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 3.1.9. This is due to missing or incorrect nonce validation on the eupago_page_content function. This makes it possible for unauthenticated attackers to update plugin 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.

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

Reaching this weakness in Eupago Gateway For Woocommerce <= 3.1.9 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 Eupago Gateway For Woocommerce the fix is 3.1.10: builds <= 3.1.9 are affected, anything from 3.1.10 onward is not.

Remediation

Update to version 3.1.10, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Eupago Gateway For Woocommerce: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Eupago Gateway For Woocommerce 3.1.10 closes this, and updating the plugin is the step that ends it.
