I wrote a little script in node.js for a hands-on lab to test Cross-Site Scriptings (XSS).

You can download it from my github: https://github.com/defensahacker/nodexss

To deploy in Google Cloud App Engine:

$ git clone https://github.com/defensahacker/nodexss.git
$ gcloud init
$ gcloud projects create xss-lab$RANDOM
$ gcloud config set project xss-lab$RANDOM
$ gcloud projects describe xss-lab$RANDOM
$ gcloud app create --project=xss-lab$RANDOM
$ gcloud app deploy
$ gcloud app logs tail -s default

To start the project from a local system:

git clone https://github.com/defensahacker/nodexss.git
docker build -t defensahacker/nodexss:1.3 --no-cache .
docker run --rm -p 8080:8080 -d defensahacker/nodexss:1.3
