CVE-2023-23373Network attack vector

Command execution via undisclosed network input

Published Oct 20, 2023 · Updated Sep 16, 2024

OS command injection in QNAP QUSBCam2 2.0.x before 2.0.3 allows attackers to execute arbitrary commands via a network. QNAP has not published the affected request, parameter, or command-construction operation that mishandles untrusted input. The CNA assessment requires user interaction but no privileges, and successful exploitation grants command execution on the NAS.
