At a glance

CVE-2023-51511 is a medium-severity Improper Authorization vulnerability in the Booster Elite for WooCommerce WordPress plugin, affecting versions < 7.1.3. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 7.1.3; sites on affected versions should update now. Disclosed December 2023, reported by Dave Jong.

Vulnerability Overview

The Booster Elite for WooCommerce plugin for WordPress is vulnerable to content injection via an unknown parameter in all versions up to and including 7.1.2 due to insufficient capability checks. This makes it possible for authenticated attackers, with subscriber access and above, to create and edit content using the plugin.

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-285: Improper Authorization

Reaching this weakness in Booster Elite for WooCommerce < 7.1.3 takes an account at Subscriber level or above. Improper authorization means a permission check exists but does not cover the case being exercised, so a caller who is allowed to do one thing is allowed to do a neighbouring thing as well.

A lower-privileged account performs an action reserved for a higher one, which on a multi-author or membership site means an ordinary user reaching administrative behaviour. For Booster Elite for WooCommerce the fix is 7.1.3: builds < 7.1.3 are affected, anything from 7.1.3 onward is not.

Remediation

Update to version 7.1.3, 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: Booster Elite for WooCommerce 7.1.3 closes this, and updating the plugin is the step that ends it.
