In Splunk Enterprise versions below 10.2.4 and 10.0.7, and Splunk Cloud Platform versions below 10.4.2604.3 and 10.2.2510.14, an unauthenticated user could create or truncate arbitrary files through a PostgreSQL sidecar service endpoint. The vulnerability exists because the PostgreSQL sidecar service endpoint lacks authentication controls, allowing any network-reachable user to invoke file operations without credentials. See Secure Splunk Enterprise in the Splunk documentation for more information.
Upgrade Splunk Enterprise to versions 10.4.0, 10.2.4 and 10.0.7, or higher. Splunk is actively monitoring and patching Splunk Cloud Platform instances.
Splunk rates this vulnerability a 9.8, Critical, with a CVSSv3.1 vector of CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H.
