TP-Link Tapo C120

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.

Tapo C120 v1 and C200 v5 do not enforce authentication for do method HTTPS onboarding connect actions after initial setup. An unauthenticated adjacent attacker can submit unauthorized wireless configuration parameters, causing the camera to attempt connection to a different network.

Successful exploitation disconnects the camera from its intended wireless network, making it unreachable on its management address, resulting in a denial-of-service condition.

Tapo C120 v1 and C200 v5 contain a NULL pointer dereference in the HTTPS onboarding connect request parser. The interface is reachable without authentication after initial setup and does not validate that a password field is present for certain authentication and encryption parameter combinations, allowing a malformed request from the same local network to crash the HTTPS service

Successful exploitation may temporarily make HTTPS management functions unavailable. Repeated malformed requests may sustain the denial-of-service condition, and recovery may in some cases require a device reboot.

Tapo C120 v1 and C200 V5 contain a vulnerability in the HTTPS onboarding scan function due to missing authentication. After initial setup, an unauthenticated attacker on the same local network can invoke the scan action and retrieve nearby wireless access-point metadata, including SSIDs, BSSIDs, authentication and encryption modes, and signal-strength information.

Successful exploitation may disclose information about the wireless environment surrounding the camera, allowing an attacker to learn elements of the local wireless topology.
