CVE-2022-23265Network attack vector

Root code execution via password-change command injection

Published Mar 9, 2022 · Updated Jul 8, 2025

Command injection in Microsoft Defender for IoT 22.0.0 through 22.1.1 allows remote authenticated users to execute code as root. The password-change mechanism passes an unvalidated user-supplied string to a system call, permitting command injection. Exploitation requires high-privilege network access or existing code execution as the www-data user; successful injection grants root execution.
