[***** Start Security-4 *****]

low: Cross-site scripting CVE-2007-3383

When reporting error messages, the SendMailServlet (part of the examples web application) did not escape user provided data before including it in the output. This enabled a XSS attack. This Servlet now filters the data before use. This issue may be mitigated by undeploying the examples web application. Note that it is recommended that the examples web application is not installed on a production system.

Affects: 4.0.0-4.0.6, 4.1.0-4.1.36
