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.

Our promise to you

  • 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

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

UPDATE 04-02-2020
We've created a new interactive Price Graph on our Product pages (For example this product)

UPDATE 21-01-2020
We've released some new features:

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

Please do not use automatic scanners

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 of 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.

Domain

  • elect.tweakers.net

Known issues

  • Open redirects in privacy consent endpoints (eg /privacygate-confirm, /privacy-wall etc)
  • Paywall can be bypassed
  • User password leaks, not originating from a vulnerability on our side, can be reported but will not be rewarded with a bounty.

Application

  • API key disclosure without proven business impact
  • Wordpress usernames disclosure
  • Pre-Auth Account takeover/OAuth squatting
  • 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
  • Missing security headers
  • 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 without proven impact/unrealistic user interaction
  • CSV Injection
  • Sessions not being invalidated (logout, enabling 2FA, etc.)
  • Tokens leaked to third parties
  • Anything related to email spoofing, SPF, DMARC or DKIM
  • Content injection without being able to modify the HTML
  • Username/email enumeration
  • Email bombing
  • HTTP Request smuggling without any proven impact
  • Homograph attacks
  • XMLRPC enabled
  • Banner grabbing/Version disclosure
  • Not stripping metadata of files
  • Same-site scripting
  • Subdomain takeover without taking over the subdomain
  • Arbitrary file upload without proof of the existence of the uploaded file
  • Blind SSRF without proven business impact (pingbacks are not sufficient)
  • Disclosed/misconfigured Google Maps API keys
  • Host header injection without proven business impact
  • Bypassing paywall using search services

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
  • 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
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

  • A remote code execution vulnerability on the production server
  • Full database access (incl. update/delete)

Critical

  • A SQL injection vulnerability
  • Access to all customer personal data or access to a targeted user
  • A numeric IDOR that allows mass write/read actions on critical features
  • Path traversal leading to the disclosure of local files

High

  • Access to random users' data (sensitive PII)
  • A stored XSS vulnerability (excluding unexploitable self-XSS)
  • Vertical authentication bypass

Medium

  • A DOM XSS vulnerability
  • Reflected XSS
  • An IDOR leading to the disclosure of non-critical data
  • A CSRF with a significant impact
  • Lateral authentication bypass

Low

  • A reflected XSS vulnerability that requires significant user interaction
  • A CSRF vulnerability in a non-critical feature
  • Open redirect

Cool-down period for zero-days

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. We may however decide to offer a bonus at our own discretion!

FAQ

Can I receive a test account?
You can register for normal Tweakers-accounts with your intigriti.me email address (max. 3 accounts).
You can find more information regarding intigriti.me addresses here: http://go.intigriti.com/intigriti_me

Is an English version of the site available?
No, we only offer this site in Dutch but we made sure that our vulnerabilities are in English ;-)

All aboard!

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.
