Unauthenticated Information Disclosure through an Edge Processor Service Endpoint in Splunk Enterprise

AI Analysis

No AI analysis yet.

Description

In Splunk Enterprise 10.4 versions below 10.4.2, an unauthenticated user could retrieve the information contained in Edge Processor pipeline configurations through a Representational State Transfer (REST) API endpoint when Edge Processor is turned on. The vulnerability does not affect versions prior to 10.4. The vulnerability exists because the Edge Processor service endpoint lacks authentication controls. For more information see System architecture of the Edge Processor solution (https://help.splunk.com/en/splunk-enterprise/process-data-at-the-edge/use-edge-processors-for-splunk-enterprise/10.4/how-the-edge-processor-solution-works/system-architecture-of-the-edge-processor-solution) in the Splunk documentation.
