A critical security vulnerability in QNAP’s QTS operating method for community-connected storage (NAS) devices could allow for cyberattackers to inject malicious code into gadgets remotely, with no authentication required.
In accordance to researchers from stability business Censys, extra than 30,000 hosts are managing a vulnerable edition of the QNAP-primarily based procedure as of push time, that means that about 98% of these products could be attacked.
