High 7.5
In plain English
A high-severity missing authentication in Splunk Enterprise from Splunk. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.5% (higher than 43% of all known vulnerabilities).
Official 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.
