The version of Tomcat installed on the remote host is prior to 8.5.41. It is, therefore, affected by a vulnerability as referenced in the fixed_in_apache_tomcat_8.5.41_security-8 advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.

"The version of Tomcat installed on the remote host is prior to 8.5.41. It is, therefore, affected by a vulnerability as
referenced in the fixed_in_apache_tomcat_8.5.41_security-8 advisory.
- The fix for CVE-2019-0199 was incomplete and did not
address HTTP/2 connection window exhaustion on write. By
not sending WINDOW_UPDATE messages for the connection
window (stream 0) clients were able to cause server-side
threads to block eventually leading to thread exhaustion
and a DoS. (CVE-2019-10072)
