CVE-2015-1266

content/browser/webui/content_web_ui_controller_factory.cc en Google Chrome anterior a 43.0.2357.130 no considera correctamente la esquema al determinar si una URL está asociada con una interfaz de usuario web SiteInstance, lo que permite a atacantes remotos evadir las restricciones de acceso a través de una URL similar, tal y como fue demostrado mediante el uso de http://gpu cuando existe una clase de interfaz de usuario web para el manejo de solicitudes chrome://gpu.

It was discovered that Chromium did not properly consider the scheme when determining whether a URL is associated with a WebUI SiteInstance. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to bypass security restrictions. It was discovered that Blink did not properly restrict the creation context during creation of a DOM wrapper. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to bypass same-origin restrictions. Various other issues were also addressed.
