The remote web server includes an example JSP application that fails to sanitize user-supplied input before using it to generate dynamic content in the ‘examples/SendMailServlet’ servlet. An unauthenticated remote attacker can exploit 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.
