Vulnerability Overview

The 404 SEO Redirection WordPress plugin through 1.3 is lacking CSRF checks in all its settings, allowing attackers to make a logged in user change the plugin's settings. Due to the lack of sanitisation and escaping in some fields, it could also lead to Stored Cross-Site Scripting issues

Technical Analysis

REMEDIATION: Update to version 1.4, 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.
