Description

KU Leuven has a very diverse web landscape. Keeping this environment and the data it contains as secure as possible is an ongoing effort. We would like to invite you to help us in this effort. We are happy to have your help to improve the security of our systems .

In scope

We are particularly interested in ways to exploit our website using:

  • unauthorized modification or deletion of webpages (defacing) or of sensitive data
  • access to backends (databases, ...)
  • application specific vulnerabilities
Out scope

The KU Leuven Central Login is out of scope in this project. For this we have another project: IAM KU Leuven

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

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

  • Write your report in Dutch or English.
  • Describe the problem in sufficient detail and include the necessary evidence, such as IP addresses, log entries, screenshots, etc.
  • Provide detailed but to-the-point reproduction steps
  • Include a clear attack scenario; a step by step guide in the PoC is highly appreciated
  • Remember: quality over quantity!
  • Only notify the ICTS department of KU Leuven of your findings, and only via this procedure. Do not publish details about the security issue through other channels. Making the problem known through other channels or the media, even before or after notifying KU Leuven via this procedure and even when not all details are provided, will be considered irresponsible behavior and can still lead to the filing of criminal charges.
  • 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 discuss bugs before they are fixed
  • You can register via our self registration, but only with your intigriti.me mail address.

Our Promise

  • If we require additional information, we may choose to contact you, if possible.
  • We will do everything possible to resolve any shortcomings as quickly as possible, and we will keep you posted.

Safe harbour for researchers

KU Leuven considers ethical hacking activities conducted consistent with the Researcher Guidelines, the Program description and restrictions (the Terms) to constitute “authorized” conduct under criminal law. KU Leuven 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, KU Leuven will take steps to make it known that your actions were conducted in compliance and with our approval.

Severity assessment

Currently we are not paying for vulnerabilities, we believe in responsible disclosure. We will however be able to increase your reputation and give you public recognition via the leaderboard!

Additionaly, in exceptional cases and depending on the issue we might send you some swag or even overrule this and offer you a reward.

FAQ

Can we receive test accounts?

No, we currently don’t share credentials of test accounts.

How long does it take to fix a vulnerability?

Our goal is to implement a fix as soon as possible. Depending on the criticality and the affected system it can take up to multiple months to implement a fix.

All aboard!
