Splunk Enterprise versions 10.4.3, 10.2.7, 10.0.10, and 9.4.15 contain a vulnerability related to improper input neutralization. The vulnerability was internally identified and addressed in the mentioned versions.

Vulnerability in Splunk Enterprise before versions 10.4.3 and 10.2.7 allows an unauthenticated user with network access to the Patroni REST API on a search head cluster member to execute attacker-controlled OS commands. The interface does not require authentication for critical configuration operations.

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.

In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, an unauthenticated user who has an embedded report token could download the dispatch archive for an embedded report search job and use exposed session material to access all relevant data and affect system integrity on the Splunk platform instance. The vulnerability is possible because the embedded report authorization flow does not block dispatch archive download requests before Splunk Enterprise begins sending the archive to the requester.

In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, an unauthenticated user who has an embedded report token could download the associated search job dispatch archive, recover session material, and use it to access all relevant data available to the report owner and affect system integrity, including by performing administrative actions when the owner holds the "admin" Splunk role. The vulnerability is possible because embedded report access does not block Representational State Transfer (REST) API dispatch archive download requests.
