"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-2024-0716 advisory.

  - In Splunk Enterprise versions below 9.2.2, 9.1.5, and 9.0.10 and Splunk Cloud Platform versions below
    9.1.2312.109, an attacker could determine whether or not another user exists on the instance by
    deciphering the error response that they would likely receive from the instance when they attempt to log
    in. This disclosure could then lead to additional brute-force password-guessing attacks. This
    vulnerability would require that the Splunk platform instance uses the Security Assertion Markup Language
    (SAML) authentication scheme. (CVE-2024-36996)

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