CVE-2024-36982Network attack vector

Daemon crash via cluster/config null pointer dereference

Published Jul 1, 2024 · Updated Feb 28, 2025

Null pointer dereference in the REST API of Splunk Enterprise and Splunk Cloud Platform allows remote attackers to crash the Splunk daemon. A request to the cluster/config endpoint causes the handler to dereference a null pointer instead of rejecting the invalid state. The endpoint is network-reachable without prior authentication, and successful exploitation interrupts the affected Splunk service without exposing or modifying data.
