"The version of Tomcat installed on the remote host is prior to 11.0.0.M12. It is, therefore, affected by multiple
vulnerabilities as referenced in the fixed_in_apache_tomcat_11.0.0-m12_security-11 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)
