The version of Tomcat installed on the remote host is prior to 9.0.81. It is, therefore, affected by multiple vulnerabilities as referenced in the fixed_in_apache_tomcat_9.0.81_security-9 advisory.

  - Improper Input Validation vulnerability in Apache Tomcat.Tomcat from 11.0.0-M1 through 11.0.0-M11, from     10.1.0-M1 through 10.1.13, from 9.0.0-M1 through 9.0.81 and from 8.5.0 through 8.5.93 did not correctly     parse HTTP trailer headers. A specially crafted, invalid trailer header could cause Tomcat to treat a     single request as multiple requests leading to the possibility of request smuggling when behind a reverse     proxy. Users are recommended to upgrade to version 11.0.0-M12 onwards, 10.1.14 onwards, 9.0.81 onwards or     8.5.94 onwards, which fix the issue. (CVE-2023-45648)

  - The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation     can reset many streams quickly, as exploited in the wild in August through October 2023. (CVE-2023-44487)

  - Incomplete Cleanup vulnerability in Apache Tomcat.When recycling various internal objects in Apache Tomcat     from 11.0.0-M1 through 11.0.0-M11, from 10.1.0-M1 through 10.1.13, from 9.0.0-M1 through 9.0.80 and from     8.5.0 through 8.5.93, an error could cause Tomcat to skip some parts of the recycling process leading to     information leaking from the current request/response to the next. Users are recommended to upgrade to     version 11.0.0-M12 onwards, 10.1.14 onwards, 9.0.81 onwards or 8.5.94 onwards, which fixes the issue.
    (CVE-2023-42795)

  - Incomplete Cleanup vulnerability in Apache Tomcat. The internal fork of Commons FileUpload packaged with     Apache Tomcat 9.0.70 through 9.0.80 and 8.5.85 through 8.5.93 included an unreleased, in progress     refactoring that exposed a potential denial of service on Windows if a web application opened a stream for     an uploaded file but failed to close the stream. The file would never be deleted from disk creating the     possibility of an eventual denial of service due to the disk being full. Users are recommended to upgrade     to version 9.0.81 onwards or 8.5.94 onwards, which fixes the issue. (CVE-2023-42794)

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