At a glance

CVE-2020-12073 is a critical-severity Incorrect Authorization vulnerability in the Responsive Starter Templates WordPress plugin, affecting versions < 2.2.6. It carries a CVSS score of 9.1 (reachable over the network; low attack complexity; high integrity impact). The issue is fixed in version 2.2.7; sites on affected versions should update now. Disclosed March 2020, reported by Chloe Chamberland.

Vulnerability Overview

The Responsive Ready Sites Importer for WordPress is vulnerable to authorization bypass due missing capability checks on several AJAX actions in versions up to, and including, 2.2.6. This makes it possible for authenticated attackers with minimal permissions, such as subscribers, to perform a variety of unauthorized actions such as importing site content.

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 integrity.

CWE-863: Incorrect Authorization

Reaching this weakness in Responsive Starter Templates < 2.2.6 takes a caller who can reach the endpoint. Incorrect authorization means a permission check exists but evaluates the wrong thing, so it passes for callers it was meant to stop.

The action runs for users the code intended to exclude, with the same effect as having no check at all. For Responsive Starter Templates the fix is 2.2.7: builds < 2.2.6 are affected, anything from 2.2.7 onward is not.

Remediation

Update to version 2.2.7, 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: Responsive Starter Templates 2.2.7 closes this, and updating the plugin is the step that ends it.
