> The AbstractAuthenticationFormServlet replaces placeholders in an HTML page with user-provided input without taking care of proper escaping of the input. Hence it is possible to construct an XSS-attack exploiting this servlet.
> This is made worse by the fact that this servlet doesn't provide an obvious way to disable it. Setting the sling.servlet.path="-" using content based configuration did the trick in my case, however.
