Descriptions

Microsoft Internet Explorer 10 and 11 mishandles integrity settings and zone settings, which allows remote attackers to bypass a sandbox protection mechanism via a crafted web site, aka "Internet Explorer Elevation of Privilege Vulnerability."

Microsoft Internet Explorer 10 y 11 no maneja adecuadamente ajustes de integridad y de zona, lo que permite a atacantes remotos eludir un mecanismo de protección sandbox a través de un sitio web manipulado, vulnerabilidad también conocida como "Internet Explorer Elevation of Privilege Vulnerability".

This vulnerability allows attackers to escape from the Enhanced Protected Mode sandbox 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 usage of the Internet Explorer Add-on Installer component. An attacker who has gained code execution within the Internet Explorer Enhanced Protected Mode sandbox can leverage this component to place a malicious HTML file in a predictable location at medium integrity. An attacker can leverage this in conjunction with other vulnerabilities to execute code under the context of the user at medium integrity.
