Description

The Football Pool plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the `shouttext` POST parameter of the Shoutbox widget in all versions up to, and including, 2.13.4 due to insufficient input sanitization and output escaping. When a shoutbox form submission fails the nonce check (or `shouttext` is empty, or the user is unable to save), the raw POST value is echoed back into a `<textarea>` element using `printf('%s', ...)` with no HTML escaping. This makes it possible for unauthenticated attackers to execute arbitrary web scripts in the browser of an authenticated victim (Subscriber-level or higher) who is tricked into submitting a crafted POST request to a page that contains the Shoutbox widget.

Executive Summary

The Football Pool plugin for WordPress has a reflected cross-site scripting (XSS) vulnerability in versions up to 2.13.4. It occurs when the shoutbox form submission fails, causing the raw POST value of the shouttext parameter to be echoed back without proper sanitization or escaping. This allows unauthenticated attackers to inject malicious scripts into the textarea element.

Detection Guidance

Check WordPress sites for the Football Pool plugin versions up to 2.13.4. Inspect POST requests to the Shoutbox widget for the shouttext parameter. Look for raw echoed output in textarea elements without HTML escaping.

Impact Analysis

An attacker could trick an authenticated user (Subscriber or higher) into submitting a crafted request, leading to arbitrary script execution in their browser. This could result in session hijacking, defacement, or theft of sensitive data like cookies or credentials.

Compliance Impact

This vulnerability could lead to unauthorized access to user data, violating GDPR's data protection principles or HIPAA's security requirements for protected health information. Organizations may face compliance penalties if exploited.

Mitigation Strategies

Update the Football Pool plugin to the latest version beyond 2.13.4. Implement input sanitization for the shouttext parameter and ensure output escaping in textarea elements. Monitor for suspicious POST requests to the Shoutbox widget.
