2 Million Network Storage Devices From WD, SeaGate, NetGear Affected by Unpatched Zero-Day Vulnerabilities

Critical vulnerabilities discovered in various NAS Devices such as WD My Book, NetGear Stora, Seagate Home, Medion LifeCloud NAS allows attackers to exploit it remotely without any user interaction.

Network Storage Systems (NAS) devices are very essential for small and Medium Business and it helps to increase the storage when you’re running out of the disk space.

New research conducted by security researchers Paulos Yibelo and Daniel Eshetu on leading NAS devices and find some of the critical vulnerabilities.

These Vulnerabilities could allow attackers to exploit the devices remotely without any user interaction and gain the highest privileges on the vulnerable system.

There are 2 (dubbed CVE-2018-18472 & CVE-2018-18471) critical Zero-day vulnerabilities addressed in this researcher that affected following 4 four popular NAS devices

1. WD My Book,
2. NetGear Stora
3. Seagate Home
4. Medion LifeCloud NAS

These Vulnerabilities allows hackers are skilled experts to gain the some of the sensitive privileges such as read files, add/remove users, add/modify existing data, or execute commands on all the above devices.

All four NAS devices tested suffer from a zero-day unauthenticated root remote command execution (preauth RCE) vulnerabilities and there are nearly 2 million affected devices online.

Researchers believe that there are many other NAS devices that suffer from similar vulnerabilities as there seems to be a missing pattern of expected from NAS devices.

XXE and Unauthenticated Remote Command Execution in Axentra Hipserv NAS firmware

Axentra Hipserv is a NAS based operating system that provides cloud-based login access and file storage that is used in different product vendors such as Netgear Stora, Seagate GoFlex Home, Medion LifeCloud.

In this case, the company provides a firmware with a web interface that mainly uses PHP as a serverside language. The web interface has a REST API endpoint and a typical web management interface with a file manager support.

According to wizcase, A vulnerability discovered in this web interface opened the endpoint to exploitation that allows to read files and perform SSRF attacks and you can read the technical details here.

WD MyBook Live Unauthenticated Remote Command Execution

WD MyCloud contains a remotely exploitable Vulnerability in WD MyBook Live that allows Unauthenticated Remote Command Execution.

It allows let attackers run commands on the device as root that vulnerability exists in the language change and modify functionality in the REST API.

Researchers advise all the users from following the steps to prevent from these vulnerabilities.

• If you are using one of the above devices and they are connected on the WAN, make sure to remove your device from the internet. (Make sure they are running only locally in the safe network)
• Make sure to contact the affected vendors and insist they release a patch as soon possible.
