What it is

Multiple

Kasa devices contain an improper authentication vulnerability in the local

device-management protocol. An unauthenticated adjacent attacker may send

management instructions to an affected device without adequate authentication

or authorization, allowing modification of the device state or management

settings. Under certain usage conditions involving interaction between the

user, mobile application, and device-cloud service, insufficient protection of

account-related communications may also expose account information.

Successful

exploitation may allow an unauthenticated adjacent-network attacker to perform

unauthorized device-management actions and disrupt legitimate user control.

Under certain conditions, account-related information may also be exposed,

potentially leading to compromise of the associated cloud account.
