"The version of Tomcat installed on the remote host is prior to 7.0.82. It is, therefore, affected by a vulnerability as
referenced in the fixed_in_apache_tomcat_7.0.82_security-7 advisory.

  - When running Apache Tomcat versions 9.0.0.M1 to 9.0.0, 8.5.0 to 8.5.22, 8.0.0.RC1 to 8.0.46 and 7.0.0 to
    7.0.81 with HTTP PUTs enabled (e.g. via setting the readonly initialisation parameter of the Default
    servlet to false) it was possible to upload a JSP file to the server via a specially crafted request. This
    JSP could then be requested and any code it contained would be executed by the server. (CVE-2017-12617)

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