Detailsinfo

A vulnerability, which was classified as problematic, has been found in Splunk Enterprise up to 10.0.9/10.2.6/10.4.2. Affected by this issue is some unknown functionality of the component SPL2 module. The manipulation with an unknown input leads to a privileges management vulnerability. Using CWE to declare the problem leads to CWE-269. The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. Impacted is confidentiality. CVE summarizes:

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.
