At a glance

CVE-2021-24993 is a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the Ultimate Product Catalog WordPress plugin, affecting versions < 5.0.26. It carries a CVSS score of 6.5 (reachable over the network; low attack complexity; high integrity impact). The issue is fixed in version 5.0.26; sites on affected versions should update now. Disclosed January 2022, reported by Krzysztof Zając.

Vulnerability Overview

The Ultimate Product Catalog WordPress plugin before 5.0.26 does not have authorisation and CSRF checks in some AJAX actions, which could allow any authenticated users, such as subscriber to call them and add arbitrary products, or change the plugin's settings for example

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-352: Cross-Site Request Forgery (CSRF)

Reaching this weakness in Ultimate Product Catalog < 5.0.26 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 Ultimate Product Catalog the fix is 5.0.26: builds < 5.0.26 are affected, anything from 5.0.26 onward is not.

Remediation

Update to version 5.0.26, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Ultimate Product Catalog: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Ultimate Product Catalog 5.0.26 closes this, and updating the plugin is the step that ends it.
