At a glance

CVE-2019-15772 is a high-severity Improper Privilege Management vulnerability in the Donations WordPress plugin, affecting versions < 1.4. It carries a CVSS score of 8.2 (reachable over the network; low attack complexity; high integrity impact). Exploitation requires no authentication. The issue is fixed in version 1.4; sites on affected versions should update now. Disclosed August 2019, reported by Jerome Bruandet.

Vulnerability Overview

The Donations plugin before 1.4 for WordPress has a nopriv_ AJAX action that allows modification of the siteurl setting.

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. A successful exploit has high impact on integrity.

CWE-269: Improper Privilege Management

Reaching this weakness in Donations < 1.4 takes no account at all. Improper privilege management means the code lets an account end up with capabilities its role should not have.

It converts a low-privileged account into an administrative one, which makes every other restriction on the site irrelevant. For Donations the fix is 1.4: builds < 1.4 are affected, anything from 1.4 onward is not.

Remediation

Update to version 1.4, or a newer patched version

How does WordSec protect against this?

This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. None of that substitutes for the fix: Donations 1.4 closes this, and updating the plugin is the step that ends it.
