At a glance

CVE-2024-4185 is a high-severity Use of Insufficiently Random Values vulnerability in the Customer Email Verification for WooCommerce WordPress plugin, affecting versions <= 2.7.4. It carries a CVSS score of 8.1 (reachable over the network; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 2.7.5; sites on affected versions should update now. Disclosed April 2024, reported by István Márton.

Vulnerability Overview

The Customer Email Verification for WooCommerce plugin for WordPress is vulnerable to Email Verification and Authentication Bypass in all versions up to, and including, 2.7.4 via the use of insufficiently random activation code. This makes it possible for unauthenticated attackers to bypass the email verification, and if both the "Login the user automatically after the account is verified" and "Verify account for current users" options are checked, then it potentially makes it possible for attackers to bypass authentication for other users.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, 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-330: Use of Insufficiently Random Values

The product uses insufficiently random numbers or values in a security context that depends on unpredictable numbers.

Remediation

Update to version 2.7.5, 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: Customer Email Verification for WooCommerce 2.7.5 closes this, and updating the plugin is the step that ends it.
