EPSS: 0.3% probability of exploitation in the next 30 days

Published: 2026-10-01 · updated 2026-10-01
Weakness: CWE-287

Description

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.
