Descriptions

Microsoft Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8, Windows 8.1, Windows Server 2012 Gold and R2, and Windows RT Gold and 8.1 do not properly restrict the exchange of keyboard and mouse data between programs at different integrity levels, which allows attackers to bypass intended access restrictions by leveraging control over a low-integrity process to launch the On-Screen Keyboard (OSK) and then upload a crafted application, aka "On-Screen Keyboard Elevation of Privilege Vulnerability."

Microsoft Windows Vista SP2, Windows Server 2008 SP2 y R2 SP1, Windows 7 SP1, Windows 8, Windows 8.1, Windows Server 2012 Gold y R2 y Windows RT Gold y 8.1 no restringen debidamente el intercambio de datos del teclado y del ratón entre programas con diferentes niveles de integridad, lo que permite a atacantes remotos evadir las restricciones de acceso mediante el aprovechamiento del control sobre un proceso de baja integridad para lanzar el On-Screen Keyboard (OSK) y posteriormente subir una aplicación manipulada, también conocido como 'vulnerabilidad de elevación de privilegios de On-Screen Keyboard.'

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Microsoft Windows. 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 handling of the On-Screen Keyboard. The issue lies in the ability to send input to the On-Screen Keyboard from a low integrity process. An attacker can leverage this vulnerability to elevate privileges and execute code under the context of the On-Screen Keyboard process.
