"It's secure, it's reliable, it's Swiss"


HHU
---
Homeless Hackers United is a small group of homeless hackers from Europe and North America. We can't afford paying for Internet access or hotel rooms.
Our only crime is to have a laptop and wireless card, and few knowledge.
Homeless state give us the freedom to access and use various open systems, accessible from public places. The following has been tested in UK, Germany, France
and Norway.

Who
---
Swisscom EuroSpot is a wireless service offered in airports, hotels and
other public places. Customers buy certain amount of time online and get access to the wireless network. The login page is of course open in order to join and
subscribe to the service.
HHU has been able to access, and validate around several hotels and public
places.

Severity
--------
Medium

Vulnerability
-------------
XSS, URL evasion

Details
-------
Swisscom access point seems to use radius servers to provide internet access to their customers. We also noticed issues on the radius authentification process that may be published later. After joining the network you will have either to buy access time or login. The following has been tested in UK, Germany, France
and Norway.

imagination it can be worst.
