Name of the Vulnerable Software and Affected Versions Splunk Enterprise versions prior to 9.0 Splunk Cloud Platform versions prior to 8.2.2203

Description The issue concerns the lack of TLS certificate validation during Splunk-to-Splunk communications by default in affected versions. This could allow an attacker with administrator credentials to add a peer without a valid certificate. Connections from misconfigured nodes without valid certificates did not fail by default.

Recommendations For Splunk Enterprise versions prior to 9.0, update to Splunk Enterprise version 9.0. For Splunk Enterprise, configure TLS host name validation for Splunk-to-Splunk communications to enable remediation. For Splunk Cloud Platform versions prior to 8.2.2203, update to Splunk Cloud Platform version 8.2.2203 or later.
