CVSS: 6.5EPSS: 0%CPEs: 17EXPL: 0CVE-2022-36326 – Resource Exhaustion Vulnerability in Western Digital devices
https://notcve.org/view.php?id=CVE-2022-36326
An uncontrolled resource consumption vulnerability issue that could arise by sending crafted requests to a service to consume a large amount of memory, eventually resulting in the service being stopped and restarted 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 the attacker to already have root privileges in order to exploit this vulnerability.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. This vulnerability allows network-adjacent attackers to create a denial-of-service condition on affected installations of Western Digital MyCloud PR4100 NAS devices. Authentication is not required to exploit this vulnerability. The specific flaw exists within the RESTSDK server. The issue results from uncontrolled resource consumption. • https://www.westerndigital.com/support/product-security/wdc-23003-western-digital-my-cloud-home-my-cloud-home-duo-and-sandisk-ibi-firmware-version-9-4-0-191 https://www.westerndigital.com/support/product-security/wdc-23006-my-cloud-firmware-version-5-26-202 • CWE-400: Uncontrolled Resource Consumption •
CVSS: 9.8EPSS: 0%CPEs: 16EXPL: 0CVE-2022-29844 – Western Digital My Cloud OS 5 arbitrary file read and write vulnerability via ftp
https://notcve.org/view.php?id=CVE-2022-29844
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. Una vulnerabilidad en el servicio FTP de los dispositivos Western Digital My Cloud OS 5 que ejecutan versiones de firmware anteriores a la 5.26.119 permite a un atacante leer y escribir archivos arbitrarios. Esto podría provocar un compromiso total del NAS y proporcionaría capacidades de ejecución remota al atacante. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Western Digital MyCloud PR4100 NAS devices. • https://www.westerndigital.com/en-in/support/product-security/wdc-23002-my-cloud-firmware-version-5-26-119 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-23: Relative Path Traversal •
CVSS: 9.8EPSS: 0%CPEs: 16EXPL: 0CVE-2022-29843 – Western Digital My Cloud OS 5 devices Command Injection Vulnerability
https://notcve.org/view.php?id=CVE-2022-29843
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. Una vulnerabilidad de inyección de comandos en la configuración del servicio DDNS de dispositivos Western Digital My Cloud OS 5 que ejecutan versiones de firmware anteriores a la 5.26.119 permite a un atacante ejecutar código en el contexto del usuario root. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Western Digital MyCloud PR4100. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of DDNS responses. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. • https://www.westerndigital.com/en-in/support/product-security/wdc-23002-my-cloud-firmware-version-5-26-119 • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
CVSS: 8.2EPSS: 0%CPEs: 16EXPL: 0CVE-2022-22999 – Cross-site Scripting Vulnerability in USB Backups App
https://notcve.org/view.php?id=CVE-2022-22999
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. Los dispositivos My Cloud de Western Digital son susceptibles a una vulnerabilidad de tipo cross side scripting que puede permitir a un usuario malicioso con altos privilegios acceder a las unidades de las que está haciéndose una copia de seguridad para construir e inyectar cargas útiles de JavaScript en el navegador de un usuario autenticado. Como resultado, puede ser posible conseguir el control de la sesión autenticada, robar datos, modificar la configuración o redirigir al usuario a sitios web maliciosos. • https://www.westerndigital.com/support/product-security/wdc-22011-my-cloud-firmware-version-5-23-114 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
CVSS: 7.8EPSS: 0%CPEs: 18EXPL: 0CVE-2022-23000 – Weak Default SSL use in Port Forwarding Service
https://notcve.org/view.php?id=CVE-2022-23000
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. • https://www.westerndigital.com/support/product-security/wdc-22011-my-cloud-firmware-version-5-23-114 • CWE-757: Selection of Less-Secure Algorithm During Negotiation ('Algorithm Downgrade') •
