CVSS: 8.8EPSS: 0%CPEs: 17EXPL: 0CVE-2022-36328 – Path Traversal Vulnerability leading to an arbitrary file read in Western Digital devices
https://notcve.org/view.php?id=CVE-2022-36328
Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability that could allow an attacker to create arbitrary shares on arbitrary directories and exfiltrate sensitive files, passwords, users and device configurations was discovered in Western Digital My Cloud Home, My Cloud Home Duo, SanDisk ibi and Western Digital My Cloud OS 5 devices. This can only be exploited once an attacker gains root privileges on the devices using an authentication bypass issue or another 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 remote attackers to create and read arbitrary files on affected installations of Western Digital MyCloud PR4100 NAS devices. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the restsdk binary. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. • 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-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •

https://notcve.org/view.php?id=CVE-2022-36327
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.

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 •

https://notcve.org/view.php?id=CVE-2023-22813
A device API endpoint was missing access controls on Western Digital My Cloud OS 5 iOS and Anroid Mobile Apps, My Cloud Home iOS and Android Mobile Apps, SanDisk ibi iOS and Android Mobile Apps, My Cloud OS 5 Web App, My Cloud Home Web App and the SanDisk ibi Web App. Due to a permissive CORS policy and missing authentication requirement for private IPs, a remote attacker on the same network as the device could obtain device information by convincing a victim user to visit an attacker-controlled server and issue a cross-site request. This issue affects My Cloud OS 5 Mobile App: before 4.21.0; My Cloud Home Mobile App: before 4.21.0; ibi Mobile App: before 4.21.0; My Cloud OS 5 Web App: before 4.26.0-6126; My Cloud Home Web App: before 4.26.0-6126; ibi Web App: before 4.26.0-6126. • https://www.westerndigital.com/support/product-security/wdc-23004-western-digital-my-cloud-os-5-my-cloud-home-sandisk-ibi-and-wd-cloud-mobile-and-web-app-update • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-862: Missing Authorization •
