Se ha detectado una vulnerabilidad de ejecución de código remota en los dispositivos My Cloud de Western Digital donde un atacante podía engañar a un dispositivo NAS para cargar mediante una llamada HTTP no segura. Esto era el resultado de una verificación insuficiente de las llamadas al dispositivo. La vulnerabilidad fue abordada al deshabilitar la comprobación de la conectividad a Internet mediante HTTP

This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Western Digital MyCloud PR4100. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the ConnectivityService service. The issue results from the lack of proper authentication of data received via HTTP. An attacker can leverage this vulnerability to execute code in the context of root.
