Summary
devolo dLAN® Cockpit is a software tool that allows devolo customers to monitor and optimise their dLAN® network using a software tool.Description
The application suffers from an unquoted search path issue impacting the service 'DevoloNetworkService' for Windows deployed as part of Devolo dLAN® Cockpit 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.Vendor
