Vulnerability Overview

The OAuth Single Sign On – SSO (OAuth Client) plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 6.24.1. This is due to missing or incorrect nonce validation on the 'delete' case in the mooauth_client_applist_page function. This makes it possible for unauthenticated attackers to make changes to the configured apps via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

Technical Analysis

REMEDIATION: Update to version 6.24.2, 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.
