"The version of Tomcat installed on the remote host is prior to 8.5.5. It is, therefore, affected by multiple
vulnerabilities as referenced in the fixed_in_apache_tomcat_8.5.5_and_8.0.37_security-8 advisory.

  - The ResourceLinkFactory implementation in Apache Tomcat 9.0.0.M1 to 9.0.0.M9, 8.5.0 to 8.5.4, 8.0.0.RC1 to
    8.0.36, 7.0.0 to 7.0.70 and 6.0.0 to 6.0.45 did not limit web application access to global JNDI resources
    to those resources explicitly linked to the web application. Therefore, it was possible for a web
    application to access any global JNDI resource whether an explicit ResourceLink had been configured or
    not. (CVE-2016-6797)

  - A malicious web application running on Apache Tomcat 9.0.0.M1 to 9.0.0.M9, 8.5.0 to 8.5.4, 8.0.0.RC1 to
    8.0.36, 7.0.0 to 7.0.70 and 6.0.0 to 6.0.45 was able to bypass a configured SecurityManager via
    manipulation of the configuration parameters for the JSP Servlet. (CVE-2016-6796)

  - When a SecurityManager is configured, a web application's ability to read system properties should be
    controlled by the SecurityManager. In Apache Tomcat 9.0.0.M1 to 9.0.0.M9, 8.5.0 to 8.5.4, 8.0.0.RC1 to
    8.0.36, 7.0.0 to 7.0.70, 6.0.0 to 6.0.45 the system property replacement feature for configuration files
    could be used by a malicious web application to bypass the SecurityManager and read system properties that
    should not be visible. (CVE-2016-6794)

  - In Apache Tomcat 9.0.0.M1 to 9.0.0.M9, 8.5.0 to 8.5.4, 8.0.0.RC1 to 8.0.36, 7.0.0 to 7.0.70 and 6.0.0 to
    6.0.45 a malicious web application was able to bypass a configured SecurityManager via a Tomcat utility
    method that was accessible to web applications. (CVE-2016-5018)

  - The Realm implementations in Apache Tomcat versions 9.0.0.M1 to 9.0.0.M9, 8.5.0 to 8.5.4, 8.0.0.RC1 to
    8.0.36, 7.0.0 to 7.0.70 and 6.0.0 to 6.0.45 did not process the supplied password if the supplied user
    name did not exist. This made a timing attack possible to determine valid user names. Note that the
    default configuration includes the LockOutRealm which makes exploitation of this vulnerability harder.
    (CVE-2016-0762)

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