CVE-2021-25646 PoC — Authenticated users can override system configurations in their requests which allows them to execute arbitrary code.

Title:Authenticated users can override system configurations in their requests which allows them to execute arbitrary code. (CVE-2021-25646)
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.

Apache Druid is susceptible to remote code execution because by default it lacks authorization and authentication. Attackers can send specially crafted requests to execute arbitrary code with the privileges of processes on the Druid server.
