Hi, Doing an assessment on mobile GWs I found that Orange Spain is adding the user MSISDN in any HTTP request sent in it´s network. That means that is really simple to get the user phone number from a Orange Spain user. On one hand, I saw that Orange Spain uses the header x-up-calling-line-id to add a user temporary ID that changes every 24h but I also found that in any HTTP request they will add the user phone number in the header X-Network-info. In particular the HTTP header looks like as follow: X-Network-info: CSD,34xxxxxxxxx,unsecured where xxxxxxxxx is the user MSISDN I notified Orange Spain more than a month ago regarding the misconfiguration and its effects on their own customers but unfortunately they just ignored it. If you are a user of Orange Spain have in mind that every web site you access with your mobile phone will get your phone number. I posted more details in http://certificateerror.blogspot.com/2010/08/orange-spain-disclosing-user-phone.html @xuf_ _______________________________________________ Full-Disclosure - We believe in it.
