IMPORTANT! We're running a Web Application Firewall (WAF). During your

testings you may experience blocks caused by our firewall. Errors generated by the WAF ("An error occurred. [...] nginx") do NOT mean that you found a vulnerability on application layer. In fact, these errors are generated by the WAF although error messages might look as they originate from the webserver. If you experience this error message, please change your IP address to be able to access our website again.
