Vulnerability Overview

The Doofinder for WooCommerce plugin for WordPress is vulnerable to Open Redirect in versions up to, and including, 1.5.49. This is due to insufficient validation on the redirect url supplied via an unknown parameter. This makes it possible for unauthenticated attackers to redirect users to potentially malicious sites if they can successfully trick them into performing an action.

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-601: URL Redirection to Untrusted Site ('Open Redirect')

Reaching this weakness in DOOFINDER Search and Discovery for WP & WooCommerce <= 1.5.49 takes no account at all. An open redirect is a page that takes a destination from the request and sends the browser there without checking that the destination belongs to the site.

A link that starts on a trusted domain finishes on an attacker's, which is what makes phishing and consent-screen abuse credible to the person clicking it. For DOOFINDER Search and Discovery for WP & WooCommerce the fix is 2.0.0: builds <= 1.5.49 are affected, anything from 2.0.0 onward is not.

Remediation

Update to version 2.0.0, or a newer patched version

How does WordSec protect against this?

Requests carrying this pattern arrive without a session, so nothing upstream of the firewall gets a chance to reject them: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: DOOFINDER Search and Discovery for WP & WooCommerce 2.0.0 closes this, and updating the plugin is the step that ends it.
