Description

Tweakers is a Dutch technology website featuring news and information about hardware, software and the Internet. We take security very serious as many of our users use our site as a trusted source. Therefore we have decided to collaborate with ethical hackers that can inform us about potential vulnerabilities in our systems. If you happen to find a vulnerability we'd be more than happy to hear about it and, if its impact is significant enough, award you a bounty as token of appreciation.

ONLY USE YOUR INTIGRITI.ME ADDRESS (in case of violation, no bounty can be awarded)

We're interested to hear about any issue that potentially compromises our company or its user's security. Before submitting a vulnerability make sure to check that it's not listed in our out of scope policy (which you can find below). If you have additional questions about our program feel free to contact us through Intigriti's support.

Please keep the impact on the site as minimal as possible by cleaning up submitted data and not impacting users other than yourself.

Out scope

ONLY USE YOUR INTIGRITI.ME ADDRESS (in case of violation, no bounty can be awarded)

While we happily welcome any input from researchers that showcase a potential vulnerability in one of our services, we have assembled a list of issues which are out of scope for this program.

Out of scope domain

  • elect.tweakers.net

Application

  • Self-XSS that cannot be used to exploit other users
  • Verbose messages/files/directory listings without disclosing any sensitive information
  • CORS misconfiguration on non sensitive endpoints
  • Missing cookie flags on non sensitive cookies
  • Missing security headers which do not present an immediate security vulnerability
  • Cross-site Request Forgery with no or low impact
  • Presence of autocomplete attribute on web forms.
  • Reverse tabnabbing
  • Bypassing rate-limits or the non-existence of rate-limits.
  • Best practices violations (password complexity, expiration, re-use, etc.)
  • Clickjacking on pages without sensitive actions
  • CSV Injection
  • Host Header Injection
  • Sessions not being invalidated (logout, enabling 2FA, ..)
  • Hyperlink injection/takeovers
  • Mixed content type issues
  • Cross-domain referer leakage
  • Anything related to email spoofing, SPF, DMARC or DKIM
  • Content injection
  • Username / email enumeration
  • E-mail bombing
  • HTTP Request smuggling without any proven impact
  • Homograph attacks
  • XMLRPC enabled
  • Banner grabbing /Version disclosure
  • Open ports without an accompanying proof-of-concept demonstrating vulnerability
  • Weak SSL configurations and SSL/TLS scan reports
  • Not stripping metadata of images
  • Disclosing API keys without proven impact

General

  • In case that a reported vulnerability was already known to the company from their own tests, it will be flagged as a duplicate.
  • Theoretical security issues with no realistic exploit scenario(s) or attack surfaces, or issues that would require complex end user interactions to be exploited, may be excluded or be lowered in severity
  • Spam, social engineering and physical intrusion
  • DoS/DDoS attacks or brute force attacks.
  • Vulnerabilities that are limited to non-current browsers (older than 3 versions) will not be accepted
  • Attacks requiring the usage of shared computers, man in the middle or compromised user accounts
  • Recently disclosed zero-day vulnerabilities in commercial products where no patch or a recent patch (< 2 weeks) is available. We need time to patch our systems just like everyone else - please give us 2 weeks before reporting these types of issues.
  • Attacks requiring unrealistic user interaction
Rules of engagement

Guidelines

ONLY USE YOUR INTIGRITI.ME ADDRESS (in case of violation, no bounty can be awarded)

  • Please clean up remnants of your testing and do not interfere with the normal operation of the site.
  • Please do NOT use automatic scanners. We cannot accept any submissions found by using automatic scanners.
  • Provide detailed but to-the point reproduction steps
  • Include a clear attack scenario, a step by step guide in the PoC is highly appreciated
  • Suggestions for mitigation are appreciated as well
  • Do not exploit the identified leak: only collect the information necessary to demonstrate its existence.
  • Do not change or delete any data or system settings.
  • Handle any found data in a responsible manner: if you can demonstrate that there is a security problem with a small portion, do not go any further
  • Please do NOT publish/discuss bugs before they are fixed

Response timeframe

  • We will respond to report in ultimately 10 days

Safe harbour for researchers

DPG Media considers ethical hacking activities conducted consistent with the Researcher Guidelines, the Program description and restrictions (the Terms) to constitute “authorized” conduct under criminal law. DPG Media will not pursue civil action or initiate a complaint for accidental, good faith violations, nor will they file a complaint for circumventing technological measures used by us to protect the scope as part of your ethical hacking activities.

If legal action is initiated by a third party against you and you have complied with the Terms, DPG Media will take steps to make it known that your actions were conducted in compliance and with our approval.

Severity assessment

All our rewards are impact based, therefore we kindly ask you to carefully evaluate a vulnerability's impact when picking a severity rating. To give you an idea of what kind of bugs belong in a certain severity rating we've put some examples below. Note that depending on the impact a bug can sometimes be given a higher/lower severity rating.

Exceptional

  • Remote Code Execution
  • Full database access (incl. update/delete)

Critical

  • Access to all customer personal details
  • SQL injection
  • Access to all user data or access to a targeted user

High

  • Stored XSS without user interaction
  • Access to random users their data
  • Privilige escalation
  • Authentication bypass on critical infrastructure

Medium

  • Reflected XSS
  • CSRF with a significant impact

Low

  • CSRF impacting user data
  • Open redirect
FAQ
