A vulnerability in the FTP service of Western Digital My Cloud OS 5 devices running firmware versions prior to 5.26.119 allows an attacker to read and write arbitrary files. This could lead to a full NAS compromise and would give remote execution capabilities to the attacker.Show less

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.Show less

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.Show less

A path traversal vulnerability was addressed in Western Digital My Cloud Home, My Cloud Home Duo and SanDisk ibi which could allow an attacker to initiate installation of custom ZIP packages and overwrite system files. This could potentially lead to a code execution.Show less

Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability was discovered via an HTTP API on Western Digital My Cloud Home; My Cloud Home Duo; and SanDisk ibi devices that could allow an attacker to abuse certain parameters to point to random locations on the file system. This could also allow the attacker to initiate the installation of custom packages at these locations. This can only be exploited once the attacker has been authenticated to the device. This issue affects: Western Digital My Cloud Home and My Cloud Home Duo versions prior to 8.11.0-113 on Linux; SanDisk ibi versions prior to 8.11.0-113 on Linux.Show less

A stack-based buffer overflow vulnerability was found on Western Digital My Cloud Home, My Cloud Home Duo, and SanDisk ibi that could allow an attacker accessing the system locally to read information from /etc/version file. This vulnerability can only be exploited by chaining it with another issue. If an attacker is able to carry out a remote code execution attack, they can gain access to the vulnerable file, due to the presence of insecure functions in code. User interaction is required for exploitation. Exploiting the vulnerability could result in exposure of information, ability to modify files, memory access errors, or system crashes.Show less

WD Discovery software executable files were signed with an unsafe SHA-1 hashing algorithm. An attacker could use this weakness to create forged certificate signatures due to the use of a hashing algorithm that is not collision-free. This could thereby impact the confidentiality of user content. This issue affects: Western Digital WD Discovery WD Discovery Desktop App versions prior to 4.4.396 on Mac; WD Discovery Desktop App versions prior to 4.4.396 on Windows.Show less

When computing a shared secret or point multiplication on the NIST P-256 curve using a public key with an X coordinate of zero, an error is returned from the library, and an invalid unreduced value is written to the output buffer. This may be leveraged by an attacker to cause an error scenario, resulting in a limited denial of service for an individual user. The scope of impact cannot extend to other components.Show less

When computing a shared secret or point multiplication on the NIST P-256 curve that results in an X coordinate of zero, the resulting output is not properly reduced modulo the P-256 field prime and is invalid. The resulting output may cause an error when used in other operations. This may be leveraged by an attacker to cause an error scenario or incorrect choice of session key in applications which use the library, resulting in a limited denial of service for an individual user. The scope of impact cannot extend to other components.Show less

When compressing or decompressing a point on the NIST P-256 elliptic curve with an X coordinate of zero, the resulting output is not properly reduced modulo the P-256 field prime and is invalid. The resulting output will cause an error when used in other operations. This may be leveraged by an attacker to cause an error scenario in applications which use the library, resulting in a limited denial of service for an individual user. The scope of impact cannot extend to other components.Show less

When compressing or decompressing elliptic curve points using the Sweet B library, an incorrect choice of sign bit is used. An attacker with user level privileges and no other user's assistance can exploit this vulnerability with only knowledge of the public key and the library. The resulting output may cause an error when used in other operations; for instance, verification of a valid signature under a decompressed public key may fail. This may be leveraged by an attacker to cause an error scenario in applications which use the library, resulting in a limited denial of service for an individual user. The scope of impact cannot extend to other components.Show less

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.Show less

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.Show less

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.Show less

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.Show less
