QNAP Systems has promptly resolved two critical vulnerabilities, CVE-2023-23368 and CVE-2023-23369, which involved command injection. They were discovered within the QTS operating system and associated applications used on their network-attached storage (NAS) devices. These vulnerabilities could have allowed remote attackers to execute arbitrary commands on affected devices, potentially taking control of them and accessing sensitive data.
The malicious server, which served as the command-and-control center for a botnet of infected devices, was responsible for launching a barrage of brute-force attacks against vulnerable NAS devices. These attacks aimed to gain unauthorized access to the devices by repeatedly attempting to guess weak or default passwords. QNAP’s Product Security Incident Response Team swiftly took action upon detecting the attacks. They effectively blocked hundreds of zombie network IPs, protecting numerous internet-exposed QNAP NAS devices from further assault. Furthermore, they successfully identified the source command-and-control server and, in collaboration with the cloud service provider, took measures to shut it down, preventing the situation from escalating further.
CVE-2023-23368, with a CVSS score of 9.8, represents a critical OS command injection flaw that a remote attacker can exploit to execute commands over a network. According to the advisory, multiple versions of QNAP operating systems are affected by this flaw. If successfully exploited, remote attackers could execute commands through a network.
CVE-2023-23369, rated with a CVSS score of 9.0, shares similarities with the potential for remote attackers to execute commands over a network. This vulnerability, described as an OS command injection issue, affects various QNAP operating systems and applications. It enables remote attackers to execute commands through a network.
“QNAP has released security patches to address these vulnerabilities, and it is urging all users to apply the patches as soon as possible.”
