Rules

What the policy asks of you, and the bug types it won't reward, quoted from Driessen Vulnerability Disclosure Program (via Intigriti)'s policy. "We" in these lines means the program, not this site.

While testing

  • Respect the scope of the program
  • Not discuss or disclose vulnerability information without prior written 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.

  • Issues based upon social engineering or physical access to a victim's device
  • Attacks requiring person-in-the-middle or compromised user accounts
  • DoS/DDoS attacks
  • Reports that state that software is out of date/vulnerable without a proof-of-concept
  • Cloud credentials / keys without proving exploitability
  • API key leakage used for insensitive activities/actions
  • Verbose messages / files / directory listings without disclosing any sensitive information
  • Anything related to email spoofing, SPF, DMARC or DKIM
  • Pre-Auth Account takeover/OAuth squatting
  • Self-XSS that can't be used to exploit other users
  • CORS misconfiguration on non-sensitive endpoints
  • Missing cookie flags
  • Missing security headers
  • Cross-site Request Forgery with no or low impact
  • Presence of autocomplete attribute on web forms
  • Reverse tabnabbing

Description

Driessen is a staffing agency for government, education and other vital sectors. We have been working exclusively for vital sectors for 30 years, making us one of the largest staffing agencies in the Netherlands. On our platform users can manage their jobs and employees (for employers). For example: candidates can find jobs and apply; employees can see payslips and send in declarations; employers can open a new job with a new vacancy or a payroll request.

Rules of engagement

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)
  • 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 😉)

In scope

Introduction

We are happy to announce our program! We've done our best to clean up our known issues and now would like to request your help to spot the ones we missed! We are specifically looking for:

  • leaking of personal data
  • horizontal / vertical privilege escalation

We would like to work together with you to better protect our systems and to remediate a vulnerability as soon as possible. Our Vulnerability Disclosure Program is however not an invitation to actively scan our business network to discover weak points.

Feedback Would you like to help us improve our program or have some feedback to share, please send your anonymous feedback here:

Program feedback link Please note this form will be checked periodically and should not be used for submission or support queries.

Out of scope

Important

We ask you not to apply on any of our vacancies. This feature is out of scope. This does not take away from the fact that this is functionality that should be tested, that is what our private bug bounty program is for. You can be invited for that if you make a valid submission.

  • Spam, social engineering and physical intrusion
  • DoS/DDoS attacks or brute force attacks
  • 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
