"According to the versions of the tomcat packages installed, the EulerOS installation on the remote host is affected by
the following vulnerabilities :

  - Apache Commons FileUpload before 1.5 does not limit the number of request parts to be processed resulting
    in the possibility of an attacker triggering a DoS with a malicious upload or series of uploads. Note
    that, like all of the file upload limits, the new configuration option (FileUploadBase#setFileCountMax) is
    not enabled by default and must be explicitly configured. (CVE-2023-24998)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security
advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional
issues.");
