Writing Secure Code: Preventing Cross-Site Scripting | |
|

Late last year, a vulnerability was discovered in a Web page in the passport.com domain that had a very subtle flaw similar to the example above. By sending a Hotmail® recipient a specially crafted e-mail, the attacker could cause script to execute in the passport.com domain because Hotmail is in the hotmail.passport.com domain. And this means the code could access the cookies generated by the Passport service used to authenticate the client. When the attacker replays those cookies (remember, a cookie is just a header in the HTTP request), he can spoof you and access data that only you could access. Not a good thing! About three years ago, no one had heard of cross-site scripting (XSS) issues, but now I think it's safe to say we hear of at least one or two issues per day on the Web. So what's the problem and why are they serious? The problem is two-fold:
This is bad because a malicious user could access another's important data, such as their cookies. | ||
