Summary
In Splunk Enterprise versions below 10.4.3, a user that holds a role with the list_spl2_modules capability could use SQL injection in SPL2 module filtering to access all relevant data available through the affected Representational State Transfer (REST) API, including private SPL2 module definitions belonging to other users.
The vulnerability is possible because Splunk Enterprise and Splunk Cloud Platform do not parameterize user-supplied values before using them in database queries for SPL2 module filtering. For more information see Manage SPL2 modules ( ) and Module permissions ( ) in the Splunk documentation.
Splunk Enterprise versions 10.2.x, 10.0.x, and 9.4.x are not affected.
- Splunk Enterprise 10.4 before 10.4.3
