Demo Code Security by Prisma Cloud with a Vulnerable Front-End

Use case: Implement Logging Middleware

To create the logging functionality needed for the new website, you have decided to reach for a third party open source software package called ‘morgan’. This package provides HTTP request logger middleware functionality.

Create a new branch

git checkout -b ccs-feature-branch

Install vulnerable code dependency

• Read about the ‘morgan’ package at https://yarnpkg.com/package/morgan
• Using the Vscode terminal window, install the ‘morgan’ package at version 1.0.0:

yarn add [email protected] -E

Open package.json in VS Code

Checkov should find a vulnerability in the morgan dependecy

Run a local Checkov scan

You may find it preferable to configure environment variables for the Prisma API URL and API Key rather than specifying them as arguments to Checkov. Feel free to use whatever method you like best.

export MY_PRISMA_API_URL="https://apix.prismacloud.io" (where x=app stack)
export MY_PRISMA_KEY="<AccessKey>::<SecretKey>"

• Using the Vscode terminal window, run a local Checkov scan:

checkov -f yarn.lock --bc-api-key $MY_PRISMA_KEY --prisma-api-url $MY_PRISMA_API_URL  --repo-id $USER/scascan --use-enforcement-rules

• Alternatively, if you have docker installed you may use this command:

docker run --rm -v $PWD:/checkovScan -w /checkovScan bridgecrew/checkov:latest -f yarn.lock --bc-api-key $MY_PRISMA_KEY --prisma-api-url $MY_PRISMA_API_URL --repo-id $USER/scascan
--use-enforcement-rules

Check in Your Code to GitHub

git add .
git commit -m "add morgan 1.0.0 depedency"
git push --set-upstream origin ccs-feature-branch

Initiate a Pull Request (PR) from GitHub

• Open your repo on github.com
• Click the Compare & pull request button
• Double check to make sure you are merging into your own repo!
• Click the 'Create Pull Request' button
• Watch Prisma Cloud perform a code review. Think of the Prisma Cloud code review this way: A Senior Developer on the team (who is super knowledgeable about security) reviews the code and checks to make sure everything is being done correctly and securely. That developer happens to be a Prisma Cloud bot.

Reset demo environment

git checkout main
git branch -D ccs-feature-branch
