Improper Neutralization of Special Elements used in a Command ('Command Injection') vulnerability that could allow an attacker to execute code in the context of the root user on a vulnerable CGI file was discovered in Western Digital My Cloud OS 5 devicesThis issue affects My Cloud OS 5: before 5.26.119.
Improper Authentication vulnerability in the encrypted volumes and auto mount features of Western Digital My Cloud devices allows insecure direct access to the drive information in the case of a device reset. This issue affects: Western Digital My Cloud My Cloud versions prior to 5.25.124 on Linux.
Insufficiently Protected Credentials vulnerability in the remote backups application on Western Digital My Cloud devices that could allow an attacker who has gained access to a relevant endpoint to use that information to access protected data. This issue affects: Western Digital My Cloud My Cloud versions prior to 5.25.124 on Linux.
The combination of primitives offered by SMB and AFP in their default configuration allows the arbitrary writing of files. By exploiting these combination of primitives, an attacker can execute arbitrary code.
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.
A limited SSRF vulnerability was discovered on Western Digital My Cloud devices that could allow an attacker to impersonate a server and reach any page on the server by bypassing access controls. The vulnerability was addressed by creating a whitelist for valid parameters.
A remote code execution vulnerability was discovered on Western Digital My Cloud devices where an attacker could trick a NAS device into loading through an unsecured HTTP call. This was a result insufficient verification of calls to the device. The vulnerability was addressed by disabling checks for internet connectivity using HTTP.
My Cloud OS 5 was vulnerable to a pre-authenticated stack overflow vulnerability on the FTP service that could be exploited by unauthenticated attackers on the network. Addressed the vulnerability by adding defenses against stack overflow issues.
A limited authentication bypass vulnerability was discovered that could allow an attacker to achieve remote code execution and escalate privileges on the My Cloud devices. Addressed this vulnerability by changing access token validation logic and rewriting rule logic on PHP scripts.
A malicious user on the same LAN could use DNS spoofing followed by a command injection attack to trick a NAS device into loading through an unsecured HTTP call. Addressed this vulnerability by disabling checks for internet connectivity using HTTP.
