Tapo C120 v1 and C200 V5
do not adequately protect login challenge data or sanitize
attacker-controlled input processed by the MacTool handler. An unauthenticated
attacker on the same local network can replay login challenge data to obtain an
administrative session, enable a privileged service that becomes accessible
after a reboot, and submit crafted input to execute arbitrary commands within
the device management process.
Successful
exploitation may allow arbitrary command execution on the camera and compromise
the confidentiality, integrity, and availability of the affected device.
Exploitation requires access from the same local network, replay of the login
challenge data, activation of the privileged service, and a device reboot.
