CWE
- CWE-89 - The software constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component.
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.
