Summary

Reflected Cross-Site Scripting (XSS) vulnerability in the Football Pool plugin for WordPress up to version 2.13.4. The 'shouttext' parameter in the Shoutbox widget is echoed back into a <textarea> without proper escaping, allowing unauthenticated attackers to execute scripts in the victim's browser.

Risk Assessment

Recommendation

Update the plugin to a patched version. Additionally, implement CSP and educate users about the risk of clicking suspicious links.

Original NVD description (English source)

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.
