At a glance

CVE-2023-49834 is a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the FOX WordPress plugin, affecting versions <= 1.4.1.4. It carries a CVSS score of 5.4 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 1.4.1.5; sites on affected versions should update now. Disclosed December 2023, reported by Brandon James Roldan (tomorrowisnew).

Vulnerability Overview

The WOOCS – WooCommerce Currency Switcher plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.4.1.4. This is due to missing or incorrect nonce validation on the delete_profiles_data function. This makes it possible for unauthenticated attackers to delete profile data via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

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 FOX <= 1.4.1.4 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 FOX the fix is 1.4.1.5: builds <= 1.4.1.4 are affected, anything from 1.4.1.5 onward is not.

Remediation

Update to version 1.4.1.5, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to FOX: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: FOX 1.4.1.5 closes this, and updating the plugin is the step that ends it.
