vulnerability as referenced in the SVD-2023-0805 advisory.

  - In Splunk Enterprise versions earlier than 8.2.12, 9.0.6, and 9.1.1, a dynamic link library (DLL) that
    ships with Splunk Enterprise references an insecure path for the OPENSSLDIR build definition. An attacker
    can abuse this reference and subsequently install malicious code to achieve privilege escalation on the
    Windows machine. (CVE-2023-40596)

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