Summary

Splunk Enterprise versions from 10.4 before 10.4.3, from 10.2 before 10.2.7, from 10.0 before 10.0.10, and from 9.4 before 9.4.15 are affected. Improper input validation (CWE-20) lets a user with a role that holds the run_collect capability write events to internal indexes outside the index access configured for that role, because whitespace in an index name is not normalized before index-access restrictions are applied. An authenticated remote attacker with low privileges can exploit this through the collect SPL command, and the impact is limited to integrity.

Description from the CNA

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 write events to internal indexes outside the index access configured for the role. The vulnerability is possible because Splunk Enterprise does not normalize whitespace in an index name before applying configured index-access restrictions for the role. For more information see collect (https://help.splunk.com/en/splunk-enterprise/search/spl-search-reference/10.4/search-commands/collect), Define roles on the Splunk platform with capabilities (https://help.splunk.com/en/splunk-enterprise/administer/manage-users-and-security/10.4/manage-splunk-platform-users-and-roles/define-roles-on-the-splunk-platform-with-capabilities), and How indexing works (https://help.splunk.com/en/splunk-enterprise/administer/manage-indexers-and-indexer-clusters/10.4/indexing-overview/how-indexing-works) in the Splunk documentation.
