CVE-2020-29563 1 Westerndigital 6 My Cloud Ex2 Ultra, My Cloud Ex4100, My Cloud Mirror Gen 2 and 3 more 2022-08-05 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 This was enabled to maintain compatibility with old or outdated home routers.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 2022-03-30 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.
