"The version of Splunk installed on the remote host is prior to tested version. It is, therefore, affected by a
vulnerability as referenced in the SVD-2023-0801 advisory.

  - In Splunk Enterprise versions below 9.1.1, 9.0.6, and 8.2.12, an attacker can craft a special web request
    that can result in reflected cross-site scripting (XSS) on the /app/search/table web endpoint.
    Exploitation of this vulnerability can lead to the execution of arbitrary commands on the Splunk platform
    instance. (CVE-2023-40592)

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