X-Intigriti: <username>

In order to gain a positive relationship and avoid misinterpretation and vagueness, we would like you to review the following program rules before you report a vulnerability. By participating in this program, you agree to respect our policy.

Program Rules

  • The use of an intigriti.me address is mandatory at all times! (Not respecting these rules means you will not be eligible for a bounty)
  • Please do NOT publicly discuss or publish any vulnerability before it has been fixed and you have received explicit permission from us to do so. You can send us a video as proof of concept, but remember to change its privacy settings to private.
  • Perform testing only on in-scope assets and respect assets and activities which are out-of-scope. If unsure or need advice, contact us.
  • We are hosting at AWS, so please take into account their penetration testing policy which you can find at https://aws.amazon.com/security/penetration-testing/
  • Make a good faith effort to avoid privacy violations, destruction of data, and interruption or degradation of our service.
  • If a vulnerability provides unintended access to data, limit the amount of data you access to the minimum required for effectively demonstrating a Proof of Concept.
  • Cease testing and submit a report immediately if you encounter any user data during testing, such as Personally Identifiable Information (PII), Personal Healthcare Information (PHI), credit card data, or proprietary information.
  • Provide an appropriate level of detail with reproducible steps so that the issue can be easily reproduced.
  • Please include the HTTP requests/responses in the report. This will help us to search for duplicate reports using the endpoint and triage reports more effectively; include the vulnerable requests in the comment using markdown.
  • Social engineering (e.g. phishing, vishing, smishing) is prohibited.
  • Do not attempt to execute Denial of Service attacks.

Our promise to you

  • We will respond to report in ultimately two weeks, probably faster!
  • We are happy to respond to any questions, please use the button in the right top corner for this.
  • We respect the safe harbour clause that you can find below

Your promise to us

  • Provide detailed but to-the point reproduction steps
  • Include a clear attack scenario. How will this affect us exactly?
  • Remember: quality over quantity!
  • Please do not discuss or post vulnerabilities without our consent (including PoC's on YouTube and Vimeo)
  • Please do not use automatic scanners -be creative and do it yourself! We cannot accept any submissions found by using automatic scanners. Scanners also won't improve your skills, and can cause a high server load (we'd like to put our time in thanking researchers rather than blocking their IP's 😉)

Severity assessment

As a general rule of thumb, severity assessments will be based upon their respective CVSS v3 score. Feel free to add your own calculation with the submission so we can see what you think and why you think that.

Exceptional

  • RCE (Remote Code Execution)

Critical

  • Access to personal data of a large amount of customers (not meaning XSS-ing them all)
  • SQL injection

High

  • Stored XSS without user interaction
  • Access to personal data of one or few customers

Medium

  • XSS
  • CSRF

Low

  • XSS that requires lots of user interaction ( > 3 steps)
  • Open redirect
FAQ

Where can we get credentials for the app?

You can self-register on the application but please don’t forget to use your @intigriti.me address.

All aboard!
Please log in or sign up on the platform

For obvious reasons we can only allow submissions or applications for our program with a valid Intigriti account.

It will only take 2 minutes to create a new one or even less to log in with an existing account, so don't hesitate and let's get started. We would be thrilled to have you as part of our community.
