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, and Splunk Secure Gateway versions from 3.10 before 3.10.11, from 3.9 before 3.9.25, and from 3.8 before 3.8.72 are affected. The affected App Key Value Store collections allow unrestricted write access, which is a missing permission restriction (CWE-732). An authenticated user without the admin or sc_admin role can modify alert and mobile-device recipient data that later alert and subscription workflows use. The flaw can be exploited with low privileges over the network and affects confidentiality, integrity and availability to a limited degree.

Description from the CNA

In Splunk Enterprise versions below 10.4.3, 10.2.7, 10.0.10, and 9.4.15, and Splunk Secure Gateway versions below 3.10.11, 3.9.25, and 3.8.72, an authenticated user who does not hold the "admin" or "sc_admin" Splunk roles could modify Splunk Secure Gateway alert and mobile-device recipient data in App Key Value Store (KV Store) collections that later alert and subscription workflows use. The vulnerability is possible because the affected collections allow unrestricted write access instead of limiting writes to authorized Splunk Secure Gateway workflows. For more information see About the app key value store (https://help.splunk.com/en/splunk-enterprise/administer/admin-manual/10.4/administer-the-app-key-value-store/about-the-app-key-value-store), KV store endpoint descriptions (https://help.splunk.com/en/splunk-enterprise/leverage-rest-apis/rest-api-reference/10.4/kv-store-endpoints/kv-store-endpoint-descriptions), and 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) in the Splunk documentation.
