>             Project: Sentry
>          Issue Type: Bug
>          Components: Sentry
>    Affects Versions: 1.8.0
>            Reporter: Alexander Kolbasov
>            Assignee: Brian Towles

> The ConfServlet class has the following code:
> {code}
>     String format = request.getParameter(FORMAT_PARAM);
>     ...
>     } else {
>       response.sendError(HttpServletResponse.SC_BAD_REQUEST, "Bad format: " + format);
>     }
> {code}
> As a result HTTP parameter is directly written to Servlet error page.  Echoing this untrusted input allows for a reflected cross site scripting vulnerability. See http://en.wikipedia.org/wiki/Cross-site_scripting for more information.
