At a glance

CVE-2019-25151 is a medium-severity Improper Privilege Management vulnerability in the CartFlows WordPress plugin, affecting versions <= 1.3.0. It carries a CVSS score of 5.4 (reachable over the network; low attack complexity). The issue is fixed in version 1.3.1; sites on affected versions should update now. Disclosed November 2019, reported by Jerome Bruandet.

Vulnerability Overview

The Funnel Builder plugin for WordPress is vulnerable to authorization bypass due to a missing capability check on the activate_plugin function in versions up to, and including, 1.3.0. This makes it possible for authenticated attackers to activate any plugin on the vulnerable service.

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.

CWE-269: Improper Privilege Management

Reaching this weakness in CartFlows <= 1.3.0 takes a caller who can reach the endpoint. 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 CartFlows the fix is 1.3.1: builds <= 1.3.0 are affected, anything from 1.3.1 onward is not.

Remediation

Update to version 1.3.1, 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: CartFlows 1.3.1 closes this, and updating the plugin is the step that ends it.
