Go to dashboardSplunk Enterprise's Edge Processor package download endpoint in the Pipeline Builders app accepts requests without authentication. Each request loads and base64-encodes the whole package in memory, so repeated requests can exhaust system resources and make the Splunk daemon stop responding.

Deployments of Splunk Enterprise below the fixed versions that have the Splunk Pipeline Builders app with Edge Processor package downloads available are exposed. The sources describe an unauthenticated endpoint reachable by remote requests, so any reachable instance on those versions is in scope until patched or the authentication setting is enabled.

splunk version and compare it against the fixed releases in the sources (10.4.4, 10.2.8, 10.0.11).10.4.4, 10.2.8, or 10.0.11 depending on the release branch in use.Each row is the first time that source carried this signal. The analyst’s rows are its own findings.
In Splunk Enterprise versions below 10.4.4, 10.2.8, and 10.0.11, an unauthenticated user could send repeated requests to the Edge Processor package download endpoint in the Splunk Pipeline Builders app. The requests could cause the Splunk daemon to consume excessive system resources and potentially stop responding. The vulnerability is possible because the endpoint accepts package download requests without authentication and reads and base64-encodes the complete package in memory for each request. After upgrading, prepare all existing Edge Processor instances, turn on authentication for Edge Processor package downloads, and restart Splunk Enterprise.
