CVE-2024-23443Network attack vector

Service interruption via malicious osquery pack upload

Published Jun 19, 2024 · Updated Aug 1, 2024

Uncontrolled resource consumption in affected Elastic Kibana releases allows remote authenticated users to interrupt the service. Elastic has not published the parser or processing operation that exhausts resources when a crafted custom osquery pack is uploaded. Exploitation requires a high-privilege account permitted to create custom osquery packs, and the reported consequence is loss of Kibana availability.
