Vulnerability Overview

The All In One WP Security & Firewall WordPress plugin before 4.4.11 does not validate, sanitise and escape the redirect_to parameter before using it to redirect user, either via a Location header, or meta url attribute, when the Rename Login Page is active, which could lead to an Arbitrary Redirect as well as Cross-Site Scripting issue. Exploitation of this issue requires the Login Page URL value to be known, which should be hard to guess, reducing the risk

Technical Analysis

REMEDIATION: Update to version 4.4.11, or a newer patched version --- IDENTIFIER: CWE-79 (Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')) The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
