Descriptions

Microsoft Internet Explorer 10 and 11 allows remote attackers to read arbitrary local files via a crafted pathname, aka "Internet Explorer Information Disclosure Vulnerability."

Las versiones 10 y 11 de Microsoft Internet Explorer permiten a atacantes remotos leer archivos locales mediante nombres de rutas manipuladas, también conocida como 'Vulnerabilidad de Revelación de informacion de Internet Explorer'.

This vulnerability allows remote attackers to partially escape AppContainer limitations on vulnerable installations of Microsoft Internet Explorer. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the IE broker process when processing a file name for reading in the routine IShdocvwBroker::MOTWCreateFileW. Using a directory junction and a symbolic link, code running inside the EPM AppContainer can read any file that the normal user account can read, bypassing the restrictions designed into EPM.
