WassUp Real Time Analytics <= 1.9.4.5 - Unauthenticated Stored XSS

The WassUp Real Time Analytics WordPress plugin through 1.9.4.5 does not escape IP address provided via some headers before outputting them back in an admin page, allowing unauthenticated users to perform Stored XSS attacks against logged in admins

The wassup plugin before 1.9.1 for WordPress has XSS via the Top stats widget or the wassupURI::add_siteurl method, a different vulnerability than CVE-2012-2633.
