CVE-2023-23362Network attack vector

Authenticated command execution via undisclosed injection locus

Published Sep 22, 2023 · Updated Sep 24, 2024

OS command injection in QNAP QTS, QuTS hero, and QuTScloud allows remote authenticated users to execute commands over the network. QNAP has not disclosed the affected component, input parameter, or operation that passes untrusted input to an operating-system command. A valid account and network access are required; successful exploitation runs attacker-supplied commands with the vulnerable service's permissions.
