"The version of Tomcat installed on the remote host is prior to 7.0.105. It is, therefore, affected by a vulnerability as
referenced in the fixed_in_apache_tomcat_7.0.105_security-7 advisory.

  - The payload length in a WebSocket frame was not correctly validated in Apache Tomcat 10.0.0-M1 to
    10.0.0-M6, 9.0.0.M1 to 9.0.36, 8.5.0 to 8.5.56 and 7.0.27 to 7.0.104. Invalid payload lengths could
    trigger an infinite loop. Multiple requests with invalid payload lengths could lead to a denial of
    service. (CVE-2020-13935)

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