Descriptions

Unspecified vulnerability in Microsoft Internet Explorer 6 through 11 allows remote attackers to execute arbitrary code with medium-integrity privileges and bypass a sandbox protection mechanism via unknown vectors, as demonstrated by ZDI during a Pwn4Fun competition at CanSecWest 2014.

Vulnerabilidad no especificada en Microsoft Internet Explorer 6 hasta la versión 11 permite a atacantes remotos ejecutar código arbitario con privilegios de integridad media y eludir un mecanismo de protección sandbox a través de vectores desconocidos, según lo demostrado por ZDI durante una competición Pwn4Fun en CanSecWest 2014.

This vulnerability allows remote attackers to execute arbitrary code 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 ability to trick the broker into loading a malicious page in a privileged context. The issue lies in the implicit trust of navigating to localhost. An attacker can leverage this vulnerability along with proxy shellcode to execute code under the context of the current user at medium integrity.
