RegVuln - Scanner Registry AppSec

📜 Este scanner analisa um servidor registry com imagens de containers Docker/OCI, e analisa TAG a TAG as vulnerabilidades existentes nelas usando Trivy da AquaSec.

💡 Ao ser executado o mesmo analisa o registry destino e analisa todas as imagens enviando-as a uma API Post previamente configurada no .config.ini ou salva os arquivos JSON no diretorio de reports também configurado no .config.ini

🛠 Instalação

Observação: Faz-se necessário baixar o Trivy confirme documentação: https://aquasecurity.github.io/trivy/latest/getting-started/installation/

Linux:

sudo apt install python3 python3-pip git curl -y
curl https://get.docker.com | sh
git clone https://github.com/cristianovisk/regvuln
cd regvuln
pip3 install -r requirements.txt
cp .config_model.ini .config.ini
sudo apt-get install wget apt-transport-https gnupg lsb-release -y
wget -qO - https://aquasecurity.github.io/trivy-repo/deb/public.key | sudo apt-key add -
echo deb https://aquasecurity.github.io/trivy-repo/deb $(lsb_release -sc) main | sudo tee -a /etc/apt/sources.list.d/trivy.list
sudo apt update
sudo apt install trivy -y

📈 Exemplo de uso com .config

Para que a analise ocorra sem problemas, é necessário editar o arquivo .config.ini com as variáveis definidas corretamente:

[REGISTRY]
dns = dns.registry.destiny.com
url = https://dns.registry.destiny.com
catalog = /v2/_catalog
user = user_to_autentication_basic
password = password_to_use

[SCANTIME]
delay_in_seconds = 3600 # Time in seconds to delay scan the images
timetoscan = 1 # ex. (timetoscan * delay_in_seconds) = limit_time_to_reescan_images

[REPORT]
output_folder = ./reports # folder to save reports generated by Trivy

[DOCKER]
cfg_cred = /home/cristiano/.docker/config.json #file that have password Docker registry
cache_images = false # enabled will save all images in cache

[DEFECT_DOJO]
url = https://dns.defectdojo.destiny.com #endpoint URL DEFECTDOJO
enabled = false #if enable or disable with True or False
api_key = KEY_API_DEFECT_DOJO # API Key DEFECT DOJO, get in WEB-GUI
product_name = NAME_REGISTRY # Name the Registry OCI to 
product_type = ENTERPRISE-BU # Name the Enterprise or BU
environment = PROD # optional unused

Após a configuração ser feita, basta executar o arquivo regvuln.py com o comando:

python3 regvuln.py --run

Todos os arquivos JSON serão salvos por padrão na pasta ./reports (caso não tenha sido alterado no .config.ini), exemplo:

cristiano@horusec:~/registry_scan_appsec$ ls -ilha ./reports/

Os dados também são centralizados em um banco SQLite por nome registry.db que é gerado no primeiro momento da execução do regvuln.py.

📈 Exemplo de uso com variáveis de ambiente em Docker

O exemplo abaixo será usado caso o RegVuln esteja com o modo Defect Dojo desabilitado.

docker run --rm -e RG_REGISTRY_DNS="ecr.amazonurl.com" \
                -e RG_REGISTRY_URL="http://ecr.amazonurl.com" \
                -v /var/run/docker.sock:/var/run/docker.sock \
                -v $PWD:/opt/regvuln/reports \
                -it cristianovisk/regvuln:latest

Já o exemplo abaixo mostra a configuração completa mínima necessária para usar com integração com Defect Dojo.

docker run --rm -e RG_REGISTRY_DNS="ecr.amazonurl.com" \
				-e RG_REGISTRY_URL="http://ecr.amazonurl.com" \
				-e RG_DEFECTDOJO_ENABLED=true \
				-v /var/run/docker.sock:/var/run/docker.sock \
				-it cristianovisk/regvuln:latest

A saída será a solicitação das variáveis obrigatórias para a integração funcionar:

2022-10-23 16:35:09 3c31c7c2a275 root[1] CRITICAL Variavel RG_DEFECTDOJO_URL vazia, favor definir para rodar
2022-10-23 16:35:09 3c31c7c2a275 root[1] CRITICAL Variavel RG_DEFECTDOJO_API_KEY vazia, favor definir para rodar
2022-10-23 16:35:09 3c31c7c2a275 root[1] CRITICAL Variavel RG_DEFECTDOJO_PRODUCT_NAME vazia, favor definir para rodar
2022-10-23 16:35:09 3c31c7c2a275 root[1] CRITICAL Variavel RG_DEFECTDOJO_PRODUCT_TYPE vazia, favor definir para rodar
2022-10-23 16:35:09 3c31c7c2a275 root[1] CRITICAL Variavel RG_DEFECTDOJO_ENV vazia, favor definir para rodar

Basta definir conforme exemplo abaixo e irá funcionar:

docker run --rm -e RG_REGISTRY_DNS="ecr.amazonurl.com" \
				-e RG_REGISTRY_URL="http://ecr.amazonurl.com" \
				-e RG_DEFECTDOJO_ENABLED=true \
                -e RG_DEFECTDOJO_URL="https://defectdojo.url.com" \
                -e RG_DEFECTDOJO_API_KEY="chave_de_api_5dc58d5d6s9x" \
                -e RG_DEFECTDOJO_PRODUCT_NAME="REGISTRY_PROD_1" \
                -e RG_DEFECTDOJO_PRODUCT_TYPE="EMPRESA" \
                -e RG_DEFECTDOJO_ENV="Production" \
				-v /var/run/docker.sock:/var/run/docker.sock \
				-it cristianovisk/regvuln:latest

💻 Configuração de CRON

Basta configurar as variáveis abaixo, e realizar o calculo, 3600 = 1 hora e timetoscan = 2 , significa que o scan será refeito em imagens já analisadas em 2 horas, e wait_time_daemon = 1800 significa que o RegVuln lerá novamente o Registry atrás de imagens novas a cada meia hora.

[SCANTIME]
wait_time_daemon = 1800
delay_in_seconds = 3600
timetoscan = 1

Para que a configuração tenha efeito como uma cron, basta executar com o argumento --daemon.
