Technical description

Splunk Enterprise 6.6.x, when configured to run as root but drop privileges to a specific non-root account, allows local users to gain privileges by leveraging access to that non-root account to modify $SPLUNK_HOME/etc/splunk-launch.conf and insert Trojan horse programs into $SPLUNK_HOME/bin, because the non-root setup instructions state that chown should be run across all of $SPLUNK_HOME to give non-root access.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
