De Lijn is the Flemish public transportation company dedicated to giving their customers a comfortable and quick ride. Due the fact that we use the latest IT equipment and servers is our security ought to be at the top of our game. For this program we are putting the focus at our web clients, APIs and of course the mobile application.
This is a responsible disclosure program without bounties.
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)
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
- Leaking of personal data
- Ordering free tickets
- Horizontal / vertical privilege escalation
- SQL injection
- Remote Code Execution (RCE)
- (Stored) Cross-site scripting (XSS)
- Server-side request forgery (SSRF)
- Cross-site request forgery (CSRF) with proven impact
- Unauthorized modification or deletion of sensitive data
Happy hunting!

- 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- Reports that state that software is out of date/vulnerable without a proof-of-concept
Mobile
- Shared links leaked through the system clipboard
- Any URIs leaked because a malicious app has permission to view URIs opened
- The absence of certificate pinning
- Sensitive data in URLs/request bodies when protected by TLS
- Lack of obfuscation
- Path disclosure in the binary
- Lack of jailbreak & root detection
- Crashes due to malformed URL Schemes
- Lack of binary protection (anti-debugging) controls, mobile SSL pinning
- Snapshot/Pasteboard leakage

- API key leakage used for insensitive activities/actions
This program follows Intigriti's triage standards
Where can we get credentials for the app?
You can self-register on the application but please don’t forget to use your @intigriti.me address.
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.
