# managing large and demanding installations. The Enterprise framework can manage and monitor an unlimited number of cameras and devices, apply

# Description:    The application suffers from an unquoted search path issue impacting the service 'SecurosCtrlService'. This could potentially allow an 
# authorized but non-privileged local user to execute arbitrary code with elevated privileges on the system. A successful attempt would require 
# the local user to be able to insert their code in the system root path undetected by the OS or other security applications where it could 
# potentially be executed during application startup or reboot. If successful, the local users code would execute with the elevated privileges
# of the application.

# Step to discover the unquoted Service:

C:\Users\user>wmic service get name, displayname, pathname, startmode | findstr /i "auto" | findstr /i /v "C:\Windows\\" | findstr /i /v """
