Name of the Vulnerable Software and Affected Versions Anker Eufy Homebase 2 version 2.1.6.9h

Description A command execution issue exists in the wifi country code update functionality of the home security binary. This is due to the lack of measures to neutralize special elements used in the operating system command.
