Summary
In Splunk Enterprise versions below 10.4.3, 10.2.7, 10.0.10, and 9.4.15, a user that holds a role with the run_collect capability could use the collect Search Processing Language (SPL) command to add attacker-controlled content to system-level messages on the Splunk platform instance.
The vulnerability is possible because the collect command does not validate the index name before processing the value. For more information see collect ( ), Define roles on the Splunk platform with capabilities ( ), and System endpoint descriptions ( ) in the Splunk documentation.
