Vulnerability Overview

The Ad Buttons plugin for WordPress is vulnerable to Cross-Site Scripting via Cross-Site Request Forgery via the ‘ab_yahurl’ parameter in versions up to, and including, 2.3.1 due to insufficient input sanitization and output escaping in addition to missing nonce protection. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

Technical Analysis

REMEDIATION: Update to version 2.3.2, or a newer patched version --- IDENTIFIER: CWE-352 (Cross-Site Request Forgery (CSRF)) The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.
