Upgrade Splunk Enterprise to versions 10.4.2, 10.2.6, 10.0.9, and 9.4.14, or higher (from the CVE record's solution, Cisco Systems, Inc.) — apply it.

In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, a user that holds a role with the schedule_search capability could run arbitrary Search Processing Language (SPL) commands with the highest level of system privilege and read every credential stored in the credential store, which can allow for disclosure and modification of all relevant data and affect system integrity and availability. The vulnerability is possible because scheduled search alert action configuration does not properly restrict user-specific alert action settings before the search scheduler runs alert actions. For more information see Create scheduled alerts (https://help.splunk.com/en/splunk-enterprise/alert-and-respond/alerting-manual/9.3/create-alerts/create-scheduled-alerts), Set up alert actions (https://help.splunk.com/en/splunk-enterprise/alert-and-respond/alerting-manual/9.3/configure-alert-actions/set-up-alert-actions), Define roles on the Splunk platform with capabilities (https://help.splunk.com/en/splunk-enterprise/administer/manage-users-and-security/10.4/manage-splunk-platform-users-and-roles/define-roles-on-the-splunk-platform-with-capabilities), and Configuration file precedence (https://help.splunk.com/en/splunk-enterprise/administer/admin-manual/10.2/administer-splunk-enterprise-with-configuration-files/configuration-file-precedence) in the Splunk documentation.

Mission impact is CISA's Mission & Well-being decision point, and only you can judge it. CISA's table makes it high when Mission Prevalence is Essential — the vulnerable component "directly provides capabilities that constitute at least one MEF for at least one entity" (MEF: mission essential function) — or when Public Well-Being Impact is Irreversible: "multiple fatalities are likely", the cyber-physical system "is likely lost or destroyed", "extreme or serious externalities" are imposed on other parties, or social systems such as elections or the financial grid "are destabilized and potentially collapse".

Data Freshness Timeline

(refreshed 19× in last 7d / 97× in last 30d)

Each row is a time one of our pipelines fetched, updated or re-scored this CVE. For example, "NVD update" means NVD published or revised its analysis for this CVE; "MITRE cvelistV5" means we ingested or refreshed it from the CNA feed. An arrow marks a change the record states ("CVSS v3 → 9.1"); EPSS and GHSA rows show the values recorded at that time, not what changed (EPSS values are rounded; hover one for the exact figures). Most recent first.

Showing the most recent 100 of 192 refreshes on record for this CVE.

A repeat, a row identical to one the same pipeline wrote less than 10 seconds earlier, is not a separate refresh and is not counted. None are among the latest 100 rows. The 92 oldest rows on record are not shown and were not checked, so the counts can still include repeats.
