"The version of Atlassian Confluence Server running on the remote host is affected by a vulnerability as referenced in
the CONFSERVER-93164 advisory.

  - 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 this issue but has instead relied only on the application's self-reported version
number.");
