Vulnerability Overview

The WP Tabs plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 2.1.14. This is due to incorrect nonce validation on the export_shortcode and import_shortcode functions. This makes it possible for unauthenticated attackers to import/export shortcodes, via 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 Custom Product Tabs for WooCommerce & WordPress Tabs Builder <= 2.1.14 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 Custom Product Tabs for WooCommerce & WordPress Tabs Builder the fix is 2.1.15: builds <= 2.1.14 are affected, anything from 2.1.15 onward is not.

Remediation

Update to version 2.1.15, or a newer patched version
