Vulnerability Overview

The BookIt plugin for WordPress is vulnerable to authentication bypass in versions up to, and including, 2.3.7. This is due to insufficient verification on the user being supplied during booking an appointment through the plugin. This makes it possible for unauthenticated attackers to log in as any existing user on the site, such as an administrator, if they have access to the email.

Technical Analysis

REMEDIATION: Update to version 2.3.8, or a newer patched version --- IDENTIFIER: CWE-288 (Authentication Bypass Using an Alternate Path or Channel) The product requires authentication, but the product has an alternate path or channel that does not require authentication.
