July 2014 by Vigil@nce
This bulletin was written by Vigil@nce : http://vigilance.fr/offer
SYNTHESIS OF THE VULNERABILITY
A local attacker can use the On-Screen Keyboard of Windows, in
order to escalate his privileges.
Impacted products: Windows 2008, Microsoft Windows 2012, Windows
7, Windows 8, Windows RT, Windows Vista
Severity: 2/4
Creation date: 08/07/2014
DESCRIPTION OF THE VULNERABILITY
The Windows Integrity mechanism associates a trust level to a
program.
The On-Screen Keyboard displays a keyboard on the screen.
However, a process with a low Integrity can be used with the
On-Screen Keyboard, to execute a program with privileges of the
current user. Technical details are unknown.
A local attacker can therefore use the On-Screen Keyboard of
Windows, in order to escalate his privileges.
