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-2026-0704 advisory.

 - In Splunk Enterprise versions below 10.4.1, 10.2.5, 10.0.8, and 9.4.13, and Splunk Cloud Platform versions below 10.5.2605.0, 10.4.2604.6, 10.3.2512.15, 10.2.2510.18, and 10.1.2507.24, a low-privileged user that does not hold the 'admin' or 'power' Splunk roles could view stored credential hashes when they access the `/servicesNS/-/-/storage/passwords` REST endpoint through the `|rest` Search Processing Language (SPL) command.<br><br>The exposure happens because the `|rest` SPL command returns the `encr_password` field in the results of the `/servicesNS/-/-/storage/passwords` REST endpoint. (CVE-2026-20298)

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

Solution

To fix the problem, perform the following procedure on Splunk Enterprise:1. Upgrade Splunk Enterprise to versions 10.4.1, 10.2.5, 10.0.8, 9.4.13, or higher.2. In the limits.conf configuration file, under the [storage_passwords_masking] stanza, set mask_encr_password = true.3. Restart the Splunk Enterprise instance.For more information, see How to edit a configuration file and the limits.conf configuration specification file.Splunk is actively monitoring and patching Splunk Cloud Platform instances.
