At a glance

CVE-2021-24668 is a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the MAZ Loader WordPress plugin, affecting versions <= 1.4.0. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 1.4.1; sites on affected versions should update now. Disclosed October 2021, reported by apple502j.

Vulnerability Overview

The MAZ Loader WordPress plugin before 1.4.1 does not enforce nonce checks, which allows attackers to make administrators delete arbitrary loaders via a CSRF attack

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.

CWE-352: Cross-Site Request Forgery (CSRF)

Reaching this weakness in MAZ Loader <= 1.4.0 takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.

An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. For MAZ Loader the fix is 1.4.1: builds <= 1.4.0 are affected, anything from 1.4.1 onward is not.

Remediation

Update to version 1.4.1, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to MAZ Loader: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: MAZ Loader 1.4.1 closes this, and updating the plugin is the step that ends it.
