CVE-2024-36987Network attack vector

XSLT injection via unrestricted preview file upload

Published Jul 1, 2024 · Updated Feb 28, 2025

Unrestricted file upload in Splunk Enterprise before 9.0.10, 9.1.5, or 9.2.2 allows remote authenticated users to stage arbitrary files. The indexing/preview REST endpoint in these releases and Splunk Cloud Platform before 9.1.2312.200 accepts arbitrary extensions while generating preview files, enabling XSLT injection. A low-privileged account without an admin or power role and enabled Splunk Web are sufficient; the direct effect is unauthorized file creation.
