Low risk30th percentile - higher than 30% of all known CVEs
Summary
In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, a user without admin or power roles could move files readable by the Splunk account into a lookup they control. This could allow access to data and affect system integrity and availability.
Risk Assessment
The risk includes unauthorized data access and potential system integrity and availability compromise.
Recommendation
Upgrade to version 10.4.2, 10.2.6, 10.0.9, or 9.4.14 or later and implement path validation in lookup configuration.
Original NVD description (English source)
In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, a user who does not hold the "admin" or "power" Splunk roles could move files that the user account running Splunk Enterprise can read into a lookup that the user controls. The user could then access all relevant data and affect system integrity and availability on the search head. The vulnerability is possible because the lookup configuration endpoint does not resolve lookup source paths before checking whether they stay inside the allowed lookup staging area.
