Critical vulnerabilities open Synology, QNAP NAS devices to attack
2022-04-29 09:26

Users of Synology and QNAP network-attached storage devices are advised to be on the lookout for patches for several critical vulnerabilities affecting Netatalk, an open-source implemention of the Apple Filing Protocol that allows Unix-like operating systems to serve file servers for Macs.

Network-attached storage devices are usually used by small-to-medium businesses and home users for storing and sharing files and backups.

Vulnerabilities affecting some of the most widely used NAS devices are often exploited to covertly mine cryptocurrency or are compromised, their contents stolen or encrypted and held for ransom.

CVE-2022-23121 and CVE-2021-31439, two vulnerabilities that may allow network-adjacent attackers to execute arbitrary code on affected installations.

Synology says that they are in the process of pushing out fixes - there's one for Synology DiskStation Manager v7.1 out already - and that users who want immediate assistence to mitigate the risk of exploitation should contact the company's technical support service.

QNAP has fixed the vulnerabilities on QTS 4.5.4.2012 build 20220419 and later and is working on other fixes.
