This repository contains a set of vulnerable Docker images for attacking the container environment compiled for Cyber_Security hackathon 2021.

Requirements

The sweep procedure was performed on Centos 8 with the latest kernel version (you are free to choose your operating system) and with necessary libraries defined below.

Clone this repository:

[root@localhost]# sudo yum -y install git
[root@localhost]# git clone https://github.com/frizzymonsta/cyber_security21.git

Run script for installing Docker and Docker-compose.

[root@localhost]# cd cyber_security21
[root@localhost]# chmod +x docker.install.centos.redhat.sh
[root@localhost]# ./docker.install.centos.redhat.sh

To install images, you need to be authorized on Docker Hub.

[root@localhost]# docker login

Scripts explanation

The repository contains the following images:

Container Bash for starting image
Kali linux container. bash/kali_container.sh
Simple mail form imitation. bash/cve-2016-10033.sh
Nginx server that hosts a simple two-page website. bash/website_sql_start.sh
Redis database. bash/website_sql_start.sh
Simple FTPd imitation. bash/cve-2015-3306.sh
Elastic search. bash/cve-2015-1427.sh
Tomcat image. bash/tomcat.sh
Ubuntu image. bash/cve-2019-5736.sh

Sources of images are contained in the images directory.

To run all images:

[root@localhost falco]# chmod +x start_all.sh
[root@localhost falco]# ./start_all.sh

To stop all images:

[root@localhost falco]# docker kill $(docker ps -q)

All images running in silent mode. Remove -d flag in scripts to avoid it.

Exploits

cve-2015-1427

Image: bash/cve-2015-1427.sh

To do: Bypass the sandbox protection mechanism and execute arbitrary shell commands via a crafted script. Access by default: localhost:9200.

cve-2015-3306

Image: bash/cve-2015-3306.sh

To do: Read and write to arbitrary files via the site CPFR and site CPTO commands. Port by default: 21.

cve-2016-10033

Image: bash/cve-2016-10033.sh

To do: Pass extra parameters to the mail command and consequently execute arbitrary code via a " (backslash double quote) in a crafted Sender property. Access by default: localhost:8383

example

cve-2019-5736

Image: bash/cve-2019-5736.sh

To do: Overwrite the host runc binary (and consequently obtain host root access) by leveraging the ability to execute a command as root within one of these types of containers: (1) a new container with an attacker-controlled image, or (2) an existing container, to which the attacker previously had write access, that can be attached with docker exec. This occurs because of file-descriptor mishandling, related to /proc/self/exe.

Win condition

Get unauthorized access to images described earlier and suggest your solutions to gain access to the three remaining containers (Kali, tomcat, portfolio website(redis and nginx, localhost:8080 by default).

The attacks of the form "Escape from the container" and "Increase privileges" are of the greatest interest.

Results are accepted through pull requests, don`t forget to add instruction in README and record demo video.

Notice: Pull requests opened on private repositories remain private.

How we choose winner?

We award points for the following actions:

Points Raising rights to root Escape from the container Implemented via third party exploit Written own exploit Third party shellcode implemented Your shellcode is written Form report Report out of shape Video optional
