Description

In Splunk Enterprise versions below 10.4.4, 10.2.8, 10.0.11, and 9.4.16, a user that holds a role with the schedule_search capability could bypass the expected safeguards in the scheduled search workflow. The user could then run risky Search Processing Language (SPL) commands that disclose or alter Splunk Enterprise data or disrupt Splunk Enterprise availability. The vulnerability is possible because the Splunk Enterprise search scheduler does not apply SPL safeguards for risky commands to scheduled searches. For more information see SPL safeguards for risky commands (https://help.splunk.com/en/splunk-enterprise/administer/manage-users-and-security/10.6/best-practices-for-splunk-platform-security/spl-safeguards-for-risky-commands) in the Splunk documentation. For more information see authorize.conf (https://help.splunk.com/en/data-management/splunk-enterprise-admin-manual/10.6/configuration-file-reference/10.6.0-configuration-file-reference/authorize.conf) in the Splunk documentation.
