It can create sophisticated traffic control and road safety systems connecting to stationary, mobile or vehicle-installed ANPR systems. CPS allows to send alert notifications directly to tablets or smartphones, it can receive and transfer data through safe encrypted protocols (HTTPS and FTPS). CPS is an open solution that offers full integration with main video surveillance software. Our CPS software connects to the national operations centre and provides law enforcement authorities with necessary tools to issue alerts. CPS is designed to guarantee cooperation among different law enforcement agencies. It allows to create a multi-user environment that manages different hierarchy levels and the related division of competences. Desc: The application suffers from an unquoted search path issue impacting the service 'Selea CarPlateServer' for Windows deployed as part of Selea CPS software application. 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 user's code would execute with the elevated privileges of the application.
