Hotmail, MSN and Amazon Susceptible to Attack via Cross Site Scripting
Acunetix WVS protects the loss of sensitive personal data due to XSS attacks
London, UK - 05 July, 2006 - A 16 year old Dutch student, Adriaan Graas, interested in Internet security and web development discovered a hack for the popular Hotmail free email service via a Cross Site Scripting attack. Microsoft, is reported to have been aware of this vulnerability for over a week but, at time of writing, has not yet fixed it.
Hacking hotmail via XSS
Vulnerabilities in MSN and Amazon left unfixed
Security researcher, Yash Kadakia, frustrated by a lack of response from Microsoft and Amazon.com, has gone public with details of flaws on MSN and Amazon. Similar to the Hotmail case, Cross Site Scripting and CRLF (Carriage Return Line Feed) injection vulnerabilities found in these sites could be used by hackers to steal "cookie" data files allowing them access to Amazon.com and MSN accounts, or to display a fake login page that could be used in phishing attacks.
Kadakia said he first notified Microsoft of the problem about a year ago but he wasn't taken seriously until late last week, when he posted screen shots of the flaw being exploited on his Web site. The Amazon.com flaw was discovered in December and to-date the vulnerability remains un-patched, according to Kadakia.
