  • Send unauthenticated GET request to /en-US/splunkd/__raw/services/server/info/server-info?output_mode=json and check for HTTP 200 response containing the string 'licenseKeys' to confirm exploitation.
  • Also probe the alternate path /__raw/services/server/info/server-info?output_mode=json (without the /en-US/splunkd prefix) as some deployments expose it directly.
  • Splunk versions 6.6.0 through 7.0.1 require authentication for this endpoint; versions 6.2.3 through 6.5.x are exploitable without credentials.
  • Use Shodan/FOFA/Google dorks to identify exposed Splunk login pages as pre-targeting step before probing the disclosure endpoint.
  • ·Affected version range is Splunk 6.2.3 through 7.0.1; versions outside this range are not confirmed vulnerable.
  • ·Authentication is required for Splunk 6.6.0–7.0.1, so unauthenticated exploitation only applies to versions 6.2.3–6.5.x.
