Descriptions
A command injection remote code execution vulnerability was discovered on Western Digital My Cloud Devices that could allow an attacker to execute arbitrary system commands on the device. The vulnerability was addressed by escaping individual arguments to shell functions coming from user input.
Se ha detectado una vulnerabilidad de ejecución de código remota por inyección de comandos en los dispositivos My Cloud de Western Digital que podría permitir a un atacante ejecutar comandos arbitrarios del sistema en el dispositivo. La vulnerabilidad fue abordada al escapar de los argumentos individuales a las funciones de shell procedentes de la entrada del usuario
This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Western Digital MyCloud PR4100. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed.
The specific flaw exists within the cloudAccess endpoint. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of root.
