"The version of Tomcat installed on the remote host is prior to 11.0.12. It is, therefore, affected by a vulnerability as
referenced in the fixed_in_apache_tomcat_11.0.12_security-11 advisory.

  - Improper Resource Shutdown or Release vulnerability in Apache Tomcat. If an error occurred (including
    exceeding limits) during the processing of a multipart upload, temporary copies of the uploaded parts
    written to disc were not cleaned up immediately but left for the garbage collection process to delete.
    Depending on JVM settings, application memory usage and application load, it was possible that space for
    the temporary copies of uploaded parts would be filled faster than GC cleared it, leading to a DoS. This
    issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.11, from 10.1.0-M1 through 10.1.46, from 9.0.0.M1
    through 9.0.109. The following versions were EOL at the time the CVE was created but are known to be
    affected: 8.5.0 though 8.5.100. Other, older, EOL versions may also be affected. Users are recommended to
    upgrade to version 11.0.12 or later, 10.1.47 or later or 9.0.110 or later which fixes the issue.

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