Strategic Overview

Vulnerability Overview

The All-In-One Security (AIOS) – Security and Firewall plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 5.2.6. This is due to missing or incorrect nonce validation on the render_404_detection() function. This makes it possible for unauthenticated attackers to block IP addresses that triggered a 404 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 5.2.7, 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.
