At a glance

CVE-2024-32107 is a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the Finale Lite WordPress plugin, affecting versions <= 2.18.0. It carries a CVSS score of 5.8 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 2.18.1; sites on affected versions should update now. Disclosed April 2024, reported by Dhabaleshwar Das.

Vulnerability Overview

The Finale Lite – Sales Countdown Timer & Discount for WooCommerce plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.18.0. This is due to missing or incorrect nonce validation on the xlo_optin_call() function. This makes it possible for unauthenticated attackers to opt into tracking 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, and no interaction from a victim user.

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

Finale Lite <= 2.18.0 carries this weakness at xlo_optin_call(), and reaching it 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 Finale Lite the fix is 2.18.1: builds <= 2.18.0 are affected, anything from 2.18.1 onward is not.

Remediation

Update to version 2.18.1, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Finale Lite: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Finale Lite 2.18.1 closes this, and updating the plugin is the step that ends it.
