The Serverless Blind XSS App
About The Project
xless is a serverless blind XSS app that can be used to identify blind XSS vulnerabilities using your own deployed version of the app. There is no need to run a full deployment process; just setup a zeit.co account and run
bash deploy.sh. That's it. You have a fully-running Blind XSS listener that uses Slack to notify you for blind XSS callbacks.
- zeit.co account: Zeit provides free plan for serverless. If you use another provider for serverless, code changes should be minimal.
- Slack Incoming Webhook URL.
$ bash deploy.sh > Deploying ~/xless under X > https://xless.now.sh [v2] [in clipboard] [4s] > Success! Deployment ready [4s]
- Use the URL for blind XSS testing
Xless will automatically serve the XSS payload, collect information, and exfiltrate it into your serverless app, which is then sent right to you in Slack.
- HTTP Referrer
- Browser DOM
- Browser Time
- Document Location
- IP Address
