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 are affected. The Discover Splunk Observability Cloud app uses an inefficient regular expression to validate input (CWE-407), so a low-privileged user without the admin or power role can submit crafted input to a REST API endpoint and cause a denial of service. Splunk Enterprise versions 9.4.x are not affected.

Description from the CNA

In Splunk Enterprise versions below 10.4.3, 10.2.7, and 10.0.10, a low-privileged user that does not hold the "admin" or "power" Splunk roles could cause a denial of service against a Representational State Transfer (REST) API endpoint in the Discover Splunk Observability Cloud app. The vulnerability is possible because the app uses an inefficient regular expression to validate input submitted through the endpoint. For more information see About configuring role-based user access (https://help.splunk.com/en/splunk-enterprise/administer/manage-users-and-security/10.4/manage-splunk-platform-users-and-roles/about-configuring-role-based-user-access), Splunk Observability Cloud previews (https://help.splunk.com/en/splunk-enterprise/search/search-manual/10.4/observability/splunk-observability-cloud-previews), and restmap.conf (https://help.splunk.com/en/splunk-enterprise/administer/admin-manual/10.4/configuration-file-reference/10.4.0-configuration-file-reference/restmap.conf) in the Splunk documentation. Splunk Enterprise versions 9.4.x are not affected.
