Synopsis

An application running on a remote web server host is affected by a vulnerability

Description

The version of Splunk installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the SVD-2023-0212 advisory.

- In Splunk Enterprise versions below 8.1.13, 8.2.10, and 9.0.4, a cross-site request forgery in the Splunk Secure Gateway (SSG) app in the kvstore_client' REST endpoint lets a potential attacker update SSG [App Key Value Store (KV store)](https://docs.splunk.com/Documentation/Splunk/latest/Admin/AboutKVstore) collections using an HTTP GET request. SSG is a Splunk-built app that comes with Splunk Enterprise. The vulnerability affects instances with SSG and Splunk Web enabled. (CVE-2023-22942)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

For Splunk Enterprise, upgrade versions to 8.1.13, 8.2.10, 9.0.4, or higher. For Splunk Cloud Platform, Splunk is actively patching the Splunk Secure Gateway app and monitoring the Splunk Cloud instances.
