"The version of Tomcat installed on the remote host is prior to 7.0.88. It is, therefore, affected by a vulnerability as
referenced in the fixed_in_apache_tomcat_7.0.88_security-7 advisory.

  - An improper handing of overflow in the UTF-8 decoder with supplementary characters can lead to an infinite
    loop in the decoder causing a Denial of Service. Versions Affected: Apache Tomcat 9.0.0.M9 to 9.0.7, 8.5.0
    to 8.5.30, 8.0.0.RC1 to 8.0.51, and 7.0.28 to 7.0.86. (CVE-2018-1336)

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