"The version of Tomcat installed on the remote host is prior to 7.0.21. It is, therefore, affected by a vulnerability as
referenced in the fixed_in_apache_tomcat_7.0.21_security-7 advisory.

  - Certain AJP protocol connector implementations in Apache Tomcat 7.0.0 through 7.0.20, 6.0.0 through
    6.0.33, 5.5.0 through 5.5.33, and possibly other versions allow remote attackers to spoof AJP requests,
    bypass authentication, and obtain sensitive information by causing the connector to interpret a request
    body as a new request. (CVE-2011-3190)

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