Tapo C120 v1 and C200 v5 contain an improper authentication vulnerability within the login authentication verification module. An attacker on the local network can exploit weaknesses in challenge parameter validation to bypass normal authentication controls and obtain administrative session tokens. Successful exploitation may allow an attacker to subsequently execute privileged management actions, enable unauthorized administrative access and temporary disruption of device services, resulting in a denial-of-service (DoS) condition.
