CVE-2021-25646

Authenticated users can override system configurations in their requests which allows them to execute arbitrary code.

Published Jan 29, 2021 CVSS 3.1 · 8.8 High EPSS 99.1% KEV · Not listed
Description
Apache Druid includes the ability to execute user-provided JavaScript code embedded in various types of requests. This functionality is intended for use in high-trust environments, and is disabled by default. However, in Druid 0.20.0 and earlier, it is possible for an authenticated user to send a specially-crafted request that forces Druid to run user-provided JavaScript code for that request, regardless of server configuration. This can be leveraged to execute code on the target machine with the privileges of the Druid server process.

Remediation

Vendor Workaround

Users should upgrade to Druid 0.20.1. Whenever possible, network access to cluster machines should be restricted to trusted hosts only.
