Known Issues

The Splunk Add-on for OpenTelemetry Collector uses an access token to ingest data to Splunk Observability Cloud. This can create potential vulnerabilities associated with the use of this technical add-on:

  • This token is transmitted from the Splunk Deployment Server in clear text over a connection secured by TLS in conjunction with infrastructure certificates.
  • This token will be stored as part of the Universal Forwarder installation in a file which can be read by administrators and the user account associated with the universal forwarder.

To remediate these issues:

  • Limit the scope/permission set of the token to ingest only.
  • Use secure certificates (signed by a trusted CA) in your deployment infrastructure.
  • Secure the universal forwarder installation according to Splunk security best practices.
