Hamburg.de - The website of the most beautiful city in Germany which is famous for its big port and its amazing atmosphere. Some days ago I had found a Non-Persistent Cross-Site Scripting vulnerability on this website and informed the team of Hamburg.de about the flaw in detail. The fix was implemented only a few hours after my notification - this is a perfect example of how to deal with security issues nowadays even if the website is more complex. This makes the team of Hamburg.de the most fastest in fixing a security vulnerability on my personal ranking-list :-) !
I would like to thank the Hamburg.de team for the professional way of working on this case!
