A user can append comments to an order using a specially crafted request that relies upon the PayFlow Pro payment module. Magento did not filter the request properly, which potentially resulted in JavaScript code being saved in database (see issue APPSEC-1240) and then executed server-side when the administrator tried to view the order. This attack could lead to a takeover of the administrator session or executing actions on behalf of administrator.
