At a glance

CVE-2024-1639 is a medium-severity Missing Authorization vulnerability in the License Manager for WooCommerce WordPress plugin, affecting versions <= 3.0.6. It carries a CVSS score of 6.5 (reachable over the network; low attack complexity; high confidentiality impact). Exploitation requires an authenticated account at Contributor level or above. The issue is fixed in version 3.0.7; sites on affected versions should update now. Disclosed June 2024, reported by Lucio Sá.

Vulnerability Overview

The License Manager for WooCommerce plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the showLicenseKey() and showAllLicenseKeys() functions in all versions up to, and including, 3.0.6. This makes it possible for authenticated attackers, with admin dashboard access (contributors by default due to WooCommerce) to view arbitrary decrypted license keys. The functions contain a referrer nonce check. However, these can be retrieved via the dashboard through the "license" JS variable. Please note that the version in trunk is patched, however, the 3.0.7 tagged version is not.

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 interaction from a victim user. A successful exploit has high impact on confidentiality.

CWE-862: Missing Authorization

License Manager for WooCommerce <= 3.0.6 carries this weakness at license, and reaching it takes an account at Contributor level or above. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.

Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. For License Manager for WooCommerce the fix is 3.0.7: builds <= 3.0.6 are affected, anything from 3.0.7 onward is not.

Remediation

Update to version 3.0.7, 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: License Manager for WooCommerce 3.0.7 closes this, and updating the plugin is the step that ends it.
