2008/09/26 セキュリティ専門家が "Clickjacking" を警告 heise Securityによると、OWASP会議 (Open Web Application Security Project) で、Robert "RSnake" HansenとJeremiah Grossman 両氏は多くのWebブラウザやWebサイトが持つ重大なセキュリティの欠陥に関する発表を行う予定だったが、急遽キャンセルになったそうだ。公にする前にベンダーに警告を送ることになったとのこと(Grossman氏のブログ)。その重大な欠陥というのはユーザを意図しないサイトに誘導させるための偽リンクで、ユーザのクリックを乗っ取る(ハイジャック)ところから、"Clickjacking" と呼ばれる。偽リンクはJavaScriptやIFRAMEなどを使って作られるが、ブラウザの問題(欠陥)と考えてよいだろう
Today is the day we can finally start talking about clickjacking. This is just meant to be a quick post that you can use as a reference sheet. It is not a thorough advisory of every site/vendor/plugin that is vulnerable - there are far too many to count. Jeremiah and I got the final word today that it was fine to start talking about this due to the click jacking PoC against Flash that was released

本家Slashdotで「Alarm Raised For "Clickjacking" Browser Exploit」という記事がありました。 Zdnet上の「Clickjacking: Researchers raise alert for scary new cross-browser exploit」という記事を話題にしたものです。 Zdnetでの記事は、OWASP NYC AppSec 2008 Conferenceで発表されるはずだった「Clickjacking」という脆弱性についてでした。 「Clickjacking」は結局発表されずに、ベンダが対策を出来る期間をあけるということでした。 Clickjackingは、IE、Firefox、Safari、Opera、Adobe Flashなど多くのブラウザで実現可能であり、かつJavaScriptとは関係がない技術ということらし

Turning XSS into Clickjacking ha.ckers.org web application security lab
Those of us who do a lot of work in the security world have come to realize that there is a ton of cross site scripting (XSS) out there. 80% of dynamic sites (or more) suffer from it. But how many sites allow you to do HTML file uploads comparatively? It’s a much smaller amount, and typically requires some sort of login before you’re allowed to do it. Often times it’s protected by login too, so it
Yesterday I published a blind analysis of the so called “Clickjacking protection” included in IE8 RC1. “Blind” because, hype aside, there was no technical documentation available, even if the feature was targeted to web developers who — in order to protect their users — should modify the way their pages are served. After a while, Microsoft’s David Ross sent me an email confirming that my wild gues
