WordPress Plugin Vulnerabilities

reCAPTCHA <= 1.6 - Admin+ Stored XSS

Description

The plugin does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup).

Proof of Concept

1. On the setting page of this plugin, enter the following payload in the input boxes. The payload is: 123" onmouseenter=alert(/XSS/) "

2. After saving, refresh the page, and then move the mouse to the input box, it will trigger the XSS.
