"The Elastic Kibana software on the remote host is missing a security update. It is, therefore, affected by
multiple arbitrary code execution vulnerabilities:

  - An attacker with All privileges to the Uptime/Synthetics feature could send a request that will attempt
    to execute JavaScript code. This could lead to the attacker executing arbitrary commands on the host
    system with permissions of the Kibana process. (CVE-2023-31415)

  - An attacker with write access to Kibana yaml or env configuration could add a specific payload that will
    attempt to execute JavaScript code. This could lead to the attacker executing arbitrary commands on the
    host system with permissions of the Kibana process. (CVE-2023-31414)

Note that Nessus has not tested for the issue but has instead relied only on the application's self-reported version 
number.");
