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.
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.
An issue was discovered on Western Digital MyCloud PR4100 2.30.172 devices. The web administration component, /web/jquery/uploader/multiuploadify.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.
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.
Addressed remote code execution vulnerability in DsdkProxy.php due to insufficient sanitization and insufficient validation of user input in Western Digital My Cloud NAS devices prior to 5.04.114
Addressed remote code execution vulnerability in regdevice.php due to insufficient validation of user input.in Western Digital My Cloud Devices prior to 5.4.1140.
Addressed remote code execution vulnerability in cgiapi.php that allowed escalation of privileges in Western Digital My Cloud NAS devices prior to 5.04.114.
Western Digital WD My Book Live and WD My Book Live Duo (all versions) have a root Remote Command Execution bug via shell metacharacters in the /api/1.0/rest/languageconfiguration language parameter. It can be triggered by anyone who knows the IP address of the affected device, as exploited in the wild in June 2021 for factory reset commands,
The web server on Western Digital TV Media Player 1.03.07 and TV Live Hub 3.12.13 allow unauthenticated remote attackers to execute arbitrary code or cause denial of service via crafted HTTP requests to toServerValue.cgi.
Western Digital My Cloud, My Cloud Home, My Cloud Home Duo, and SanDisk ibi devices were vulnerable to an impersonation attack that could allow an unauthenticated attacker to gain access to user data. This issue affects My Cloud OS 5 devices: before 5.25.132; My Cloud Home and My Cloud Home Duo: before 8.13.1-102; SanDisk ibi: before 8.13.1-102.
An authentication bypass issue via spoofing was discovered in the token-based authentication mechanism that could allow an attacker to carry out an impersonation attack.
This issue affects My Cloud OS 5 devices: before 5.26.202.
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.
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.
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.
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.)
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.
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.
Addressed remote code execution vulnerability in AvailableApps.php that allowed escalation of privileges in Western Digital My Cloud NAS devices prior to 5.04.114 (issue 3 of 3).
Addressed multiple stack buffer overflow vulnerabilities that could allow an attacker to carry out escalation of privileges through unauthorized remote code execution in Western Digital My Cloud devices before 5.04.114.
Western Digital WD My Book World through II 1.02.12 suffers from Broken Authentication, which allows an attacker to access the /admin/ directory without credentials. An attacker can easily enable SSH from /admin/systemadvanced.php?lang=en and login with the default root password welc0me.
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 loginmgr.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.
Western Digital WD My Cloud v04.05.00-320 devices embed the session token (aka PHPSESSID) in filenames, which makes it easier for attackers to bypass authentication by listing a directory. NOTE: this can be exploited in conjunction with CVE-2018-7171 for remote authentication bypass within a product that uses My Cloud.
Addressed a remote code execution vulnerability by resolving a command injection vulnerability and closing an AWS S3 bucket that potentially allowed an attacker to execute unsigned code on My Cloud Home devices.
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.
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.
Western Digital My Cloud devices before OS5 have a nobody account with a blank password.
Western Digital My Cloud devices before OS5 do not use cryptographically signed Firmware upgrade files.
Improper Neutralization of Special Elements used in a Command ('Command Injection') vulnerability that could allow an attacker to execute code in the context of the root user on a vulnerable CGI file was discovered in Western Digital My Cloud OS 5 devicesThis issue affects My Cloud OS 5: before 5.26.119.
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.
Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability that could allow an attacker to write files to locations with certain critical filesystem types leading to remote code execution was discovered in Western Digital My Cloud Home, My Cloud Home Duo, SanDisk ibi and Western Digital My Cloud OS 5 devices. This issue requires an authentication bypass issue to be triggered before this can be exploited. This issue affects My Cloud Home and My Cloud Home Duo: before 9.4.0-191; ibi: before 9.4.0-191; My Cloud OS 5: before 5.26.202.
