> cross-site scripting vulnerability in ConfServlet
> -------------------------------------------------
>
> Key: SENTRY-1665
> URL: https://issues.apache.org/jira/browse/SENTRY-1665
> Project: Sentry
> Issue Type: Bug
> Components: Sentry
> Affects Versions: 1.8.0
> Reporter: Alexander Kolbasov
> Assignee: Brian Towles
> Labels: bite-sized, newbie, security
> Attachments: SENTRY-1665.001-sentry-ha-redesign.patch

> 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.
