CVE-2024-27124Network attack vector

Unauthenticated root code execution via password reset

Published Apr 26, 2024 · Updated Aug 2, 2024

OS command injection in QNAP QTS, QuTS hero, and QuTScloud allows remote attackers to execute commands through password reset requests. The password-reset handler fails to validate a user-supplied string before passing it to a system call, allowing injected input to run as root. Authentication is not required, but the vendor's assessment requires user interaction and high-complexity conditions.
