OS Command Injection vulnerability in Western Digital My Cloud devices

Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability that was caused by a command that read files from a privileged location and created a system command without sanitizing the read data. This command could be triggered by an attacker remotely to cause code execution and gain a reverse shell in Western Digital My Cloud OS 5 devices.This issue affects My Cloud OS 5: before 5.26.119.

Western Digital has identified a security vulnerability in the Replay Protected Memory Block (RPMB) protocol as specified in multiple standards for storage device interfaces, including all versions of eMMC, UFS, and NVMe. The RPMB protocol is specified by industry standards bodies and is implemented by storage devices from multiple vendors to assist host systems in securing trusted firmware. Several scenarios have been identified in which the RPMB state may be affected by an attacker without the knowledge of the trusted component that uses the RPMB feature.

DLL hijacking in the WD Discovery Installer in Western Digital WD Discovery 5.2.730 on Windows allows a local attacker to execute arbitrary code via placement of a crafted dll in the installer's search path.

Misconfiguration in node.js causing a code execution in WD Discovery

WD Discovery versions prior to 5.0.589 contain a misconfiguration in the Node.js environment settings that could allow code execution by utilizing the 'ELECTRON_RUN_AS_NODE' environment variable. Any malicious application operating with standard user permissions can exploit this vulnerability, enabling code execution within WD Discovery application's context. WD Discovery version 5.0.589 addresses this issue by disabling certain features and fuses in Electron. The attack vector for this issue requires the victim to have the WD Discovery app installed on their device.

Unchecked buffer in Dynamic DNS client

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.

Pre-authenticated stack overflow vulnerability on FTP Service

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.

Insecure file and directory permissions on EdgeRover

File and directory permissions have been corrected to prevent unintended users from modifying or accessing resources. It would be more difficult for an authenticated attacker to now traverse through the files and directories. This can only be exploited once an attacker has already found a way to get authenticated access to the device.

Western Digital My Cloud OS 5 and My Cloud Home Unauthenticated Arbitrary File Write Vulnerability in Netatalk

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.

Buffer Overflow Vulnerability in Western Digital My Cloud Home Products and SanDisk ibi

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.

Post-Auth Path Traversal Vulnerability Allows to Custom Package Installation via HTTP API

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.

Path traversal Vulnerability in Western Digital My Cloud Home, My Cloud Home Duo and SanDisk ibi Devices

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.

Authentication issue with the encrypted volumes and auto mount feature in My Cloud devices

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.

Remote Backups Application Discloses Stored Credentials

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.

An issue was discovered on Western Digital MyCloud PR4100 2.30.172 devices. The web administration component, /web/jquery/uploader/multi_uploadify.php, provides multipart upload functionality that is accessible without authentication and can be used to place a file anywhere on the device's file system. This allows an attacker the ability to upload a PHP shell onto the device and obtain arbitrary code execution as root.

The WD My Cloud (aka com.wdc.wd2go) application 4.0.0 for Android does not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.

Directory traversal vulnerability in opt/arkeia/wui/htdocs/index.php in the WD Arkeia virtual appliance (AVA) with firmware before 10.2.9 allows remote attackers to read arbitrary files and execute arbitrary PHP code via a ..././ (dot dot dot slash dot slash) in the lang Cookie parameter, as demonstrated by a request to login/doLogin.

main_internet.php on the Western Digital My Net N600 and N750 with firmware 1.03.12 and 1.04.16, and the N900 and N900C with firmware 1.05.12, 1.06.18, and 1.06.28, allows remote attackers to discover the cleartext administrative password by reading the "var pass=" line within the HTML source code.

Western Digital My Cloud OS 5 devices Command Injection Vulnerability

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.

Western Digital My Cloud OS 5 arbitrary file read and write vulnerability via ftp

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.

Host Boot ROM Code Vulnerability in Systems Implementing UFS Boot Feature

Western Digital has identified a weakness in the UFS standard that could result in a security vulnerability. This vulnerability may exist in some systems where the Host boot ROM code implements the UFS Boot feature to boot from UFS compliant storage devices. The UFS Boot feature, as specified in the UFS standard, is provided by UFS devices to support platforms that need to download the system boot loader from external non-volatile storage locations. Several scenarios have been identified in which adversaries may disable the boot capability, or revert to an old boot loader code, if the host boot ROM code is improperly implemented. UFS Host Boot ROM implementers may be impacted by this vulnerability. UFS devices are only impacted when connected to a vulnerable UFS Host and are not independently impacted by this vulnerability. When present, the vulnerability is in the UFS Host implementation and is not a vulnerability in Western Digital UFS Devices. Western Digital has provided details of the vulnerability to the JEDEC standards body, multiple vendors of host processors, and software solutions providers.
