Descriptions

Western Digital My Cloud, My Cloud Home, My Cloud Home Duo, and SanDisk ibi devices were vulnerable to an impersonation attack that could allow an unauthenticated attacker to gain access to user data.
This issue affects My Cloud OS 5 devices: before 5.25.132; My Cloud Home and My Cloud Home Duo: before 8.13.1-102; SanDisk ibi: before 8.13.1-102.

This vulnerability allows remote attackers to bypass authentication on affected installations of Western Digital MyCloud PR4100 NAS devices. Some user interaction is required to exploit this vulnerability.
The specific flaw exists within the way the device connects with cloud services. The issue results from the lack of authentication prior to allowing access to functionality. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of root.
