"The remote instance of Mort Bay Jetty includes a test servlet,
'webapps/test/jsp/dump.jsp', that fails to sanitize user-supplied
input before using it to generate dynamic content.  An unauthenticated,
remote attacker may be able to leverage this issue to inject arbitrary
HTML or script code into a user's browser to be executed within the
security context of the affected site. 

Similar issues reportedly exist with the 'webapps/snoop.jsp'' servlet
as well as Jetty itself, although Nessus did not check for them.");
