Vulnerability Title
Improper Access Control through Embedded Reports in Splunk Enterprise
Source: CVE Program / CVE List V5
Vulnerability Description
In Splunk Enterprise versions below 10.4.1, 10.2.6, 10.0.9, and 9.4.14, an unauthenticated user who can read the Hypertext Markup Language (HTML) source of a page that embeds a Splunk report could use exposed session material to access all relevant data and affect system integrity. The vulnerability is possible because the dispatch archive download path does not correctly enforce the embedded-report authorization boundary and includes sensitive session material in archived search-job data. For more information see Additional configuration for embedded reports (https://help.splunk.com/en/splunk-enterprise/create-dashboards-and-reports/reporting-manual/10.4/report-management/additional-configuration-for-embedded-reports) and Embed scheduled reports (https://help.splunk.com/en/splunk-enterprise/create-dashboards-and-reports/reporting-manual/10.4/report-management/embed-scheduled-reports) in the Splunk documentation.
