CVE-2020-14102Network attack vector

Administrator-to-root command execution via DDNS hostname

Published Jan 13, 2021 · Updated Aug 4, 2024

Command injection in Xiaomi Mi Router AX1800 firmware before 1.0.336 allows remote authenticated users to execute commands as root. The DDNS hostname-processing path accepts an administrator-supplied hostname as command input; Xiaomi has not disclosed the affected function or exact neutralization failure. Administrative access to the router's network management interface is required, and successful exploitation grants full control of the device.
