This is still a thing in Splunk Enterprise. Depending on your environment such as your version, deployment size and production hrs etc, you may find it easier to upgrade to the versions that are safe from this vuln. These are 8.2.11.2, 9.0.5.1 or 9.1.0.2 for Splunk Enterprise. If you do this option, you still need to purge some logs as they may still pose a risk, Splunk recommends removing the log files in $SPLUNK_HOME/var/logs/splunk/ Hope this helps!
