Summary

Splunk Enterprise versions from 10.4 before 10.4.3, from 10.2 before 10.2.7, and from 10.0 before 10.0.10 contain an authorization bypass (CWE-639) in SPL2 module permissions. A user who holds a role with the edit_spl2_module_permissions capability can use a REST API to read permission grants for SPL2 modules they are not allowed to view, because the product does not check that the user can read the requested app first. Exploitation requires low-privileged authenticated access, and the impact is limited to confidentiality.

Description from the CNA

In Splunk Enterprise versions below 10.4.3, 10.2.7, and 10.0.10, a user that holds a role with the edit_spl2_module_permissions capability could use the affected Representational State Transfer (REST) API to access permission grants for SPL2 modules that the user does not have permission to view. The vulnerability is possible because Splunk Enterprise does not verify that the user can read the requested app before the affected REST API returns SPL2 module permission grants. For more information see Module permissions (https://help.splunk.com/en/splunk-enterprise/search/spl2-search-manual/modules-statements-and-views/module-permissions) and Manage SPL2 modules (https://help.splunk.com/en/splunk-enterprise/search/spl2-search-manual/multiple-searches-in-an-spl2-module/manage-spl2-modules) in the Splunk documentation. Splunk Enterprise versions 9.4.x are not affected.
