Title
Improper Authentication and Credential Exposure in Multiple TP-Link Kasa Devices
Summary
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.

Title
Insufficient Cryptographic Protections in Local Device Communication Protocol on Multiple TP-Link Kasa Smart Home Devices
Summary
Multiple
TP-Link Kasa smart home devices contain insufficient cryptographic protections
in the local device communication protocol. An adjacent network attacker may
intercept, replay or forge locally exchanged control messages, potentially
resulting in unauthorized device control.
Successful
exploitation could allow an attacker to manipulate the operational state of an
affected device, resulting in unauthorized state changes, disruption of normal
device functionality or a denial-of-service condition.

Title
Improper Authentication and Credential Exposure in Multiple TP-Link Kasa Devices
Summary
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.
Severity

Exploitation: none
Automatable: no

Title
Insufficient Cryptographic Protections in Local Device Communication Protocol on Multiple TP-Link Kasa Smart Home Devices
Summary
Multiple
TP-Link Kasa smart home devices contain insufficient cryptographic protections
in the local device communication protocol. An adjacent network attacker may
intercept, replay or forge locally exchanged control messages, potentially
resulting in unauthorized device control.
Successful
exploitation could allow an attacker to manipulate the operational state of an
affected device, resulting in unauthorized state changes, disruption of normal
device functionality or a denial-of-service condition.
Severity
SSVC
Exploitation: none
Automatable: no
