CVE-2020-29563 1 Westerndigital 6 My Cloud Ex2 Ultra, My Cloud Ex4100, My Cloud Mirror Gen 2 and 3 more 2022-08-06 7.5 HIGH 9.8 CRITICAL
An issue was discovered on Western Digital My Cloud OS 5 devices before 5.07.118. A NAS Admin authentication bypass vulnerability could allow an unauthenticated user to gain access to the device.
CVE-2022-23000 1 Westerndigital 18 My Cloud, My Cloud Dl2100, My Cloud Dl2100 Firmware and 15 more 2022-08-03 N/A 7.8 HIGH
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 This was enabled to maintain compatibility with old or outdated home routers.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-2022-22999 1 Westerndigital 16 My Cloud Dl2100, My Cloud Dl2100 Firmware, My Cloud Dl4100 and 13 more 2022-08-01 N/A 4.8 MEDIUM
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-2020-28970 1 Westerndigital 6 My Cloud Ex2 Ultra, My Cloud Ex4100, My Cloud Mirror Gen 2 and 3 more 2022-04-26 7.5 HIGH 9.8 CRITICAL
An issue was discovered on Western Digital My Cloud OS 5 devices before 5.06.115. A NAS Admin authentication bypass vulnerability could allow an unauthenticated user to execute privileged commands on the device via a cookie. (In addition, an upload endpoint could then be used by an authenticated administrator to upload executable PHP scripts.)
CVE-2020-28940 1 Westerndigital 6 My Cloud Ex2 Ultra, My Cloud Ex4100, My Cloud Mirror Gen 2 and 3 more 2022-04-26 7.5 HIGH 9.8 CRITICAL
On Western Digital My Cloud OS 5 devices before 5.06.115, the NAS Admin dashboard has an authentication bypass vulnerability that could allow an unauthenticated user to execute privileged commands on the device.
CVE-2020-28971 1 Westerndigital 6 My Cloud Ex2 Ultra, My Cloud Ex4100, My Cloud Mirror Gen 2 and 3 more 2022-04-26 7.5 HIGH 9.8 CRITICAL
An issue was discovered on Western Digital My Cloud OS 5 devices before 5.06.115. A NAS Admin authentication bypass vulnerability could allow an unauthenticated user to execute privileged commands on the device via a cookie, because of insufficient validation of URI paths.
CVE-2022-22995 1 Westerndigital 22 My Cloud, My Cloud Dl2100, My Cloud Dl2100 Firmware and 19 more 2022-03-31 7.5 HIGH 9.8 CRITICAL
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-2022-22993 1 Westerndigital 11 My Cloud, My Cloud Dl2100, My Cloud Dl4100 and 8 more 2022-03-18 8.3 HIGH 8.8 HIGH
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 1 Westerndigital 11 My Cloud, My Cloud Dl2100, My Cloud Dl4100 and 8 more 2022-03-17 8.3 HIGH 8.8 HIGH
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-2022-22994 1 Westerndigital 11 My Cloud, My Cloud Dl2100, My Cloud Dl4100 and 8 more 2022-03-15 7.5 HIGH 9.8 CRITICAL
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-2022-22992 1 Westerndigital 11 My Cloud, My Cloud Dl2100, My Cloud Dl4100 and 8 more 2022-02-04 10.0 HIGH 9.8 CRITICAL
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.
CVE-2022-22989 1 Westerndigital 11 My Cloud, My Cloud Dl2100, My Cloud Dl4100 and 8 more 2022-01-21 7.5 HIGH 9.8 CRITICAL
My Cloud OS 5 was vulnerable to a pre-authenticated stack overflow vulnerability on the FTP service. Addressed the vulnerability by adding defenses against stack overflow issues.
CVE-2022-22991 1 Westerndigital 11 My Cloud, My Cloud Dl2100, My Cloud Dl4100 and 8 more 2022-01-21 8.3 HIGH 8.8 HIGH
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-2020-27744 1 Westerndigital 6 My Cloud Ex2 Ultra, My Cloud Ex4100, My Cloud Firmware and 3 more 2021-12-06 10.0 HIGH 9.8 CRITICAL
An issue was discovered on Western Digital My Cloud NAS devices before 5.04.114. They allow remote code execution with resultant escalation of privileges.
CVE-2021-3310 1 Westerndigital 9 My Cloud Dl2100, My Cloud Dl4100, My Cloud Ex2100 and 6 more 2021-03-17 4.6 MEDIUM 7.8 HIGH
Western Digital My Cloud OS 5 devices before 5.10.122 mishandle Symbolic Link Following on SMB and AFP shares. This can lead to code execution and information disclosure (by reading local files).
CVE-2019-9950 1 Westerndigital 18 My Cloud, My Cloud Dl2100, My Cloud Dl2100 Firmware and 15 more 2020-08-24 7.5 HIGH 9.8 CRITICAL
Western Digital My Cloud, My Cloud Mirror Gen2, My Cloud EX2 Ultra, My Cloud EX2100, My Cloud EX4100, My Cloud DL2100, My Cloud DL4100, My Cloud PR2100 and My Cloud PR4100 firmware before 2.31.174 is affected by an authentication bypass vulnerability. The login_mgr.cgi file checks credentials against /etc/shadow. However, the "nobody" account (which can be used to access the control panel API as a low-privilege logged-in user) has a default empty password, allowing an attacker to modify the My Cloud EX2 Ultra web page source code and obtain access to the My Cloud as a non-Admin My Cloud device user.
CVE-2019-9949 1 Westerndigital 18 My Cloud, My Cloud Dl2100, My Cloud Dl2100 Firmware and 15 more 2019-05-29 9.0 HIGH 8.8 HIGH
Western Digital My Cloud Cloud, Mirror Gen2, EX2 Ultra, EX2100, EX4100, DL2100, DL4100, PR2100 and PR4100 before firmware 2.31.183 are affected by a code execution (as root, starting from a low-privilege user session) vulnerability. The cgi-bin/webfile_mgr.cgi file allows arbitrary file write by abusing symlinks. Specifically, this occurs by uploading a tar archive that contains a symbolic link, then uploading another archive that writes a file to the link using the "cgi_untar" command. Other commands might also be susceptible. Code can be executed because the "name" parameter passed to the cgi_unzip command is not sanitized.
