CVE-2026-102369: CWE-287 Improper Authentication in TP-Link Systems Inc. Tapo C200 v5
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.
AI Analysis
Technical Summary
CVE-2026-102369 describes an improper authentication vulnerability (CWE-287) in TP-Link Tapo C120 v1 and C200 v5 cameras. The devices fail to adequately protect login challenge data and do not sanitize attacker-controlled input processed by the MacTool handler. This allows an unauthenticated attacker on the same local network to replay login challenge data to obtain an administrative session, enable a privileged service that remains active after reboot, and submit crafted input to execute arbitrary commands within the device management process. Successful exploitation compromises the device's confidentiality, integrity, and availability.
Potential Impact
An attacker with local network access can gain administrative control over the affected cameras, execute arbitrary commands, and maintain privileged access even after device reboot. This leads to full compromise of the device's confidentiality, integrity, and availability.
Mitigation Recommendations
No patch or official fix information is currently available. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is released, restrict local network access to the affected devices to trusted users only and monitor for suspicious activity.
