CVE-2023-47565 is an OS command injection vulnerability affecting legacy QNAP VioStor NVR models running QVR Firmware 4.x. The flaw allows an authenticated user to inject and execute operating system commands via network-accessible functionality exposed by the device. The issue is classified as command injection, indicating insufficient neutralization of attacker-controlled input before it is incorporated into a system command. Successful exploitation can result in remote execution of arbitrary commands on the affected NVR.
