At a glance

CVE-2024-1592 is a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the Complianz GDPR/CCPA Cookie Consent Banner WordPress plugin, affecting versions <= 6.5.6. 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 7.0.0; sites on affected versions should update now. Disclosed March 2024, reported by Krzysztof Zając.

Vulnerability Overview

The Complianz – GDPR/CCPA Cookie Consent plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 6.5.6. This is due to missing or incorrect nonce validation on the process_delete function in class-DNSMPD.php. This makes it possible for unauthenticated attackers to delete GDPR data requests 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 Complianz GDPR/CCPA Cookie Consent Banner <= 6.5.6 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 Complianz GDPR/CCPA Cookie Consent Banner the fix is 7.0.0: builds <= 6.5.6 are affected, anything from 7.0.0 onward is not.

Remediation

Update to version 7.0.0, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Complianz GDPR/CCPA Cookie Consent Banner: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Complianz GDPR/CCPA Cookie Consent Banner 7.0.0 closes this, and updating the plugin is the step that ends it.
