"The version of Tomcat installed on the remote host is prior to 7.0.50. It is, therefore, affected by multiple
vulnerabilities as referenced in the fixed_in_apache_tomcat_7.0.50_security-7 advisory.

  - Apache Tomcat 6.x before 6.0.37 and 7.x before 7.0.30 does not properly handle chunk extensions in chunked
    transfer coding, which allows remote attackers to cause a denial of service by streaming data.
    (CVE-2012-3544)

  - Apache Tomcat before 6.0.39, 7.x before 7.0.50, and 8.x before 8.0.0-RC10 allows attackers to obtain
    Tomcat internals information by leveraging the presence of an untrusted web application with a
    context.xml, web.xml, *.jspx, *.tagx, or *.tld XML document containing an external entity declaration in
    conjunction with an entity reference, related to an XML External Entity (XXE) issue. (CVE-2013-4590)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
