At a glance

CVE-2023-3162 is a critical-severity Authentication Bypass Using an Alternate Path or Channel vulnerability in the Payment Gateway of Stripe for WooCommerce WordPress plugin, affecting versions <= 3.7.7. It carries a CVSS score of 9.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 3.7.8; sites on affected versions should update now. Disclosed August 2023, reported by István Márton.

Vulnerability Overview

The Stripe Payment Plugin for WooCommerce plugin for WordPress is vulnerable to authentication bypass in versions up to, and including, 3.7.7. This is due to insufficient verification on the user being supplied during a Stripe checkout through the plugin. This allows unauthenticated attackers to log in as users who have orders, who are typically customers.

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, and no interaction from a victim user. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-288: Authentication Bypass Using an Alternate Path or Channel

Reaching this weakness in Payment Gateway of Stripe for WooCommerce <= 3.7.7 takes a caller who can reach the endpoint. Authentication bypass through an alternate path means the application has a second route to a protected action that skips the checks the primary route performs.

The protection on the main path becomes irrelevant, because the attacker simply uses the route that never asks. For Payment Gateway of Stripe for WooCommerce the fix is 3.7.8: builds <= 3.7.7 are affected, anything from 3.7.8 onward is not.

Remediation

Update to version 3.7.8, or a newer patched version

How does WordSec protect against this?

Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: Payment Gateway of Stripe for WooCommerce 3.7.8 closes this, and updating the plugin is the step that ends it.
