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-2023-0210 advisory.
Note that Nessus has not tested for this issue but has instead relied only on the applicationβs self-reported version number.

"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-2023-0210 advisory.
- In Splunk Enterprise versions below 8.1.13, 8.2.10, and 9.0.4, aliases of the collect' search processing
language (SPL) command, including summaryindex', sumindex', stash',' mcollect', and meventcollect',
were not designated as safeguarded commands. The commands could potentially allow for the exposing of data
to a summary index that unprivileged users could access. The vulnerability requires a higher privileged
user to initiate a request within their browser, and only affects instances with Splunk Web enabled.
