At a glance

CVE-2021-4377 is a medium-severity Exposure of Sensitive Information to an Unauthorized Actor vulnerability in the Doneren met Mollie WordPress plugin, affecting versions <= 2.8.4. It carries a CVSS score of 6.5 (reachable over the network; low attack complexity; high confidentiality impact). The issue is fixed in version 2.8.5; sites on affected versions should update now. Disclosed January 2021, reported by Jerome Bruandet.

Vulnerability Overview

The Doneren met Mollie plugin for WordPress is vulnerable to Sensitive Data Exposure in versions up to, and including, 2.8.5 via the dmm_export_donations() function which is called via the admin_post_dmm_export hook due to missing capability checks. This can allow authenticated attackers to extract a CSV file that contains sensitive information about the donors.

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-200: Exposure of Sensitive Information to an Unauthorized Actor

Doneren met Mollie <= 2.8.4 carries this weakness at dmm_export_donations(), and reaching it takes a caller who can reach the endpoint. Sensitive information exposure means data the application intended to keep internal is returned to a caller who should not be able to see it.

The disclosed data — credentials, tokens, customer records or internal paths — is usually worth more as material for a follow-up attack than as an end in itself. For Doneren met Mollie the fix is 2.8.5: builds <= 2.8.4 are affected, anything from 2.8.5 onward is not.

Remediation

Update to version 2.8.5, or a newer patched version

How does WordSec protect against this?

The fix is the thing that ends this: Doneren met Mollie 2.8.5 closes this, and updating the plugin is the step that ends it.
