CyberRota Analysis

AI-Generated

Splunk Enterprise versions prior to 10.4.1, 10.2.6, 10.0.9, and 9.4.14 are vulnerable to unauthorized access, allowing unauthenticated users to exploit exposed session materials in embedded reports to gain access to sensitive data and potentially compromise system integrity. Organizations using these affected versions should prioritize remediation to mitigate the risk of data exposure and unauthorized actions within their Splunk environments. Immediate action is essential for any entity relying on Splunk for data reporting and analysis.

Original NVD 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.
