Summary
In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, a low-privileged user that does not hold the "admin" or "power" Splunk roles could inject Structured Query Language (SQL) through the Representational State Transfer (REST) API, causing Splunk Enterprise to evaluate attacker-controlled text as part of a database query.
The SQL injection is possible because the REST API incorporates user-supplied filter values into database queries without proper neutralization.
