By participating in this program, you agree to:

  • Respect the Community Code of Conduct
  • Respect the Intigriti Terms and Conditions
  • Respect the scope of the program
  • Not discuss or disclose vulnerability information without prior written consent (including PoC's on YouTube and Vimeo)

Reporting vulnerabilities

When reporting a vulnerability, please do your best to explain the vulnerability using clear, reproducible steps, which will help us validate the vulnerability as quickly as possible. Reports with a clear proof of concept, especially videos, are usually higher quality, which allow Personio to reproduce and fix vulnerabilities quicker, and that is why we will also be rewarding researchers submitting high quality reports additional amounts when deemed appropriate.

We are happy to announce our first bug bounty program! We've done our best to clean most of our known issues and now would like to request your help to spot the ones we missed!

We are specifically looking for the following issues:

  • Cross Tenant Data Leakage / Access
  • RCE on Personio infrastructure
  • Personio Production database access
  • Personio Infrastructure access
  • Sensitive Personio company financial or customer information publicly available

A word on tiers:
Tier 1 and Tier 2 assets are similar to what you can find in other bug bounty programs. The goal of Tier 3 is to motivate researchers to submit things that could harm Personio, even if they are not explicitly in the URLs listed in the other tiers. Although there are minimum bounties for the Exceptional and Critical severities, our goal for this tier is to reward using an impact-based approach, and we can bump the payout with bonuses if the impact of the reported vulnerability is extraordinary.

  • Vulnerabilities that only work on software that no longer receive security updates
  • Attacks requiring physical access to a victim's computer/device, man in the middle or compromised user accounts
  • Recently discovered zero-day vulnerabilities found in in-scope assets within 14 days after the public release of a patch or mitigation may be reported, but are usually not eligible for a bounty
  • Reports that state that software is out of date/vulnerable without a proof-of-concept
Severity assessment

This program follows Intigriti's contextual CVSS standard.
Here are some examples of vulnerabilities and how we match them to criticalities by applying the business modifier.

Exceptional

  • Remote Code Execution
  • Access to AWS Keys

Critical

  • Access to all users or accounts
  • User-account or account takeover
  • Multi-tenant PII access

High

  • Stored XSS (only cross-tenant)
  • Access to one user or account
  • Privilege escalation within the same account with account take-over or similar (making yourself admin, gaining access to salary info, …)

Medium

  • Stored XSS (single-tenant)
  • Reflected Cross-Site scripting with no or limited (1 step) user interaction
  • Privilege escalation within the same account that exposes GDPR-protected data

Low

  • Reflected Cross-Site scripting with user interaction
  • Cross-Site scripting that does not work on either chrome, safari or internet explorer
  • Full path disclosure with limited information
FAQ

Where can we get credentials for the app?

Testers must create their own instances according to the format below using Trial instances at https://www.personio.com/free-trial/. The environments come preloaded with realistic user data and will be registered with the actual tester’s email address in advance of any bounty activity. Trial accounts are limited to a 14 day trial period and new accounts need to be created when these expire.

Register with your @intigriti.me address

Make sure you name your company in format: sec-test-<intigriti handle>-<nn>. This way, your own instance will have the following naming format for its URI: https://sec-test-<intigriti handle>-<nn>.personio.de/.

For example, if your researcher handle is tom55, you can name your company sec-test-tom55-01 to sec-test-tom55-99.

How can I change the app language to English?

After creating a trial account, your account might be in German or another language you might not understand. This can easily be changed by following the instruction in this documentation page: https://support.personio.de/hc/en-us/articles/360004896117-How-do-I-change-the-language-of-my-Personio-account

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.
