CVE-2024-22170
Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in Western Digital My Cloud ddns-start on Linux allows Overflow Buffers.This issue affects My Cloud: before 5.29.102.
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.
CVE-2022-22999
Western Digital My Cloud devices are vulnerable to a cross side scripting vulnerability that can allow a malicious user with elevated privileges access to drives being backed up to construct and inject JavaScript payloads into an authenticated user's browser. As a result, it may be possible to gain control over the authenticated session, steal data, modify settings, or redirect the user to malicious websites. The scope of impact can extend to other components.
CVE-2022-23000
The Western Digital My Cloud Web App [https://os5.mycloud.com/] uses a weak SSLContext when attempting to configure port forwarding rules. This was enabled to maintain compatibility with old or outdated home routers. By using an "SSL" context instead of "TLS" or specifying stronger validation, deprecated or insecure protocols are permitted. As a result, a local user with no privileges can exploit this vulnerability and jeopardize the integrity, confidentiality and authenticity of information transmitted. The scope of impact cannot extend to other components and no user input is required to exploit this vulnerability.
CVE-2022-22995
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.
CVE-2022-22994
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.
CVE-2022-22993
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.
CVE-2022-22990
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.
CVE-2022-22991
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.
CVE-2022-22989
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.
