https://notcve.org/view.php?id=CVE-2022-29843
A command injection vulnerability in the DDNS service configuration of Western Digital My Cloud OS 5 devices running firmware versions prior to 5.26.119 allows an attacker to execute code in the context of the root user. Una vulnerabilidad de inyección de comandos en la configuración del servicio DDNS de dispositivos Western Digital My Cloud OS 5 que ejecutan versiones de firmware anteriores a la 5.26.119 permite a un atacante ejecutar código en el contexto del usuario root. 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 handling of DDNS responses. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. • https://www.westerndigital.com/en-in/support/product-security/wdc-23002-my-cloud-firmware-version-5-26-119 • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
