At a glance

This record tracks a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the Shopping Cart & eCommerce Store WordPress plugin, affecting versions <= 5.2.6. It carries a CVSS score of 6.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 5.3.0; sites on affected versions should update now. Disclosed April 2022.

Vulnerability Overview

The WP Easycart plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 5.2.6. This is due to missing or incorrect nonce validation on the 'wp-easycart-submit-newsletter' function. This makes it possible for unauthenticated attackers to perform an unknown action granted they can trick a site administrator into performing an action such as clicking on a link. The impact of this vulnerability is unknown.

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)

Shopping Cart & eCommerce Store <= 5.2.6 carries this weakness at wp-easycart-submit-newsletter, 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 Shopping Cart & eCommerce Store the fix is 5.3.0: builds <= 5.2.6 are affected, anything from 5.3.0 onward is not.

Remediation

Update to version 5.3.0, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Shopping Cart & eCommerce Store: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Shopping Cart & eCommerce Store 5.3.0 closes this, and updating the plugin is the step that ends it.
