a Damn Vulnerable Serverless Application
Damn Vulnerable Serverless Application (DVSA) is a deliberately vulnerable application aiming to be an aid for security professionals to test their skills and tools in a legal environment, help developers better understand the processes of securing serverless applications and to aid both students & teachers to learn about serverless application security in a controlled class room environment.
The aim of DVSA is to practice some of the most common serverless vulnerabilities, with a simple straightforward interface.
Please note, there are both documented and undocumented vulnerabilities with this software. This is intentional. You are encouraged to try and discover as many issues as possible.
Disclaimer
Do not install DVSA on a production account
We do not take responsibility for the way in which any one uses this application (DVSA). We have made the purposes of the application clear and it should not be used maliciously. We have given warnings and taken measures to prevent users from installing DVSA on to production accounts.
Deployment
Application Repository
-
Deploy DVSA from the AWS Serverless Application Repository
-
After deployment is complete. Click on 'View CloudFormation Stack'
-
Under 'Outputs' you will find the URL for the application (DVSA Website URL)
Serverless Framework
You must run serverless deploy commands with an environment variable profile (e.g. AWS_PROFILE=<aws-profile-name>) instead of the serverless argument.
Clone Project
git clone git@github.com:OWASP/DVSA.git
Install Serverless
npm install -g serverless
Install AWS-CLI
pip install awscli --upgrade --user
Verify AWS-CLI Installation
aws --version
If you get a "command not found" error, see the "Steps to Take after Installation" section here.
Configure AWS-CLI for your Account
aws configure
Install dependencies
npm i
Deploy Backend
sls deploy
Build Client
npm run-script client:build
Deploy Client
sls client deploy
Running locally
Run Client
npm run-script client:start
Note: This will only work if you previously deployed the backend. If this fails, confirm you still have a be-stack.json file at the root of this project.
Run Backend
npm start
If you want to point your local client to your local backend, edit your be-stack.json and set ServiceEndpoint to http://localhost:3000. Note that you will still be using the Cognito pools in AWS.
Email subscription
DVSA sends receipts in the email (which will help you in hacking it). You can use the built-in Inbox page within the application to get the emails and obtain the receipts.
Note: each user will be assigned an email from mailsac.com which will be automatically verified. Real emails will be sent to their account and will appear in the application Inbox page. All this is transparent to the user and the deployer).
Note: to make the email verification script work your default AWS region has to be "US East (N. Virginia)", for example by setting region = us-east-1 in your ~/.aws/config file
Alternatively, if you want users to receive emails to their registered email account (e.g. gmail), use one of the followings:
- Send an email verification link to email address, by running the following command (after clicking on the received link, emails will also be sent to their actual email address):
aws ses verify-email-identity --email-address <your_email>
- Request a sending limit increase. This will allow your entire cloud account to send emails to any address.
