Descriptions

Microsoft Internet Explorer 10 and 11 allows remote attackers to gain privileges via a crafted web site, aka "Internet Explorer Elevation of Privilege Vulnerability."

Microsoft Internet Explorer 10 y 11 permite a atacantes remotos ganar privilegios a través de un sitio web manipulado, también conocido como 'vulnerabilidad de la elevación de privilegios de Internet Explorer.'

This vulnerability allows attackers to escape the Extended Protection Mode sandbox of 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 actions of the IE add-on installer. The installer can take a web page created by attacker code running in the context of the IE App Container and copy it to a location where it can be rendered as an Intranet webpage, which, by default, invokes IE as a medium-integrity process in the context of the user.
