Winiary Pomysł Na... - ominięcie Frame-Busting

Na pewno mieliście okazję spotkać się ze zjawiskiem takim jak Clickjacking. Obecnie chyba jedyną skuteczną metodą na zabezpieczenie przed tego typu atakami jest wysłanie nagłówka X-Frame-Options, dzięki któremu mamy możliwość kontrolować czy strona ma być załadowana w ramce czy nie. Innym spotykanym zabezpieczeniem jest tzw. Frame Busting. Podczas próby załadowania strony z takim zabezpieczeniem w ramce, następuje stosowna walidacja i przekierowanie strony nadrzędnej na tą, która próbuje być załadowana.

W tym poście przedstawię chyba mało odkrywczy, ale działający pomysł na ominięcie Frame Buster'a. Testowane na przeglądarce Google Chrome 28.0.1500.5-dev działającej pod Slackware Linux 14.0. Jako przykład posłuży strona popularnej stacji radiowej, która:

1. Nie stosuje X-Frame-Options
2. Używa Frame Bustingu:

if (window.parent.frames.length != 0) {
   window.parent.location = window.location;
  }



Z pomocą przyjdzie nam atrybut sandbox. Tutaj przykładowy fragment kodu, pozwalający na załadowanie strony http://eska.pl w ramce:

<iframe sandbox="allow-scripts allow-same-origin allow-forms" src="http://eska.pl" width="800">

Opcja, którą pominęliśmy allow-top-navigation. Dodana w atrybucie sandbox pozwoli na przekierowanie (czego nie chcemy). Jak widać - udało nam się osiągnąć cel:
