Title
Denial-of-Service via Oversized Encrypted Credential Input in TP-Link Tapo C200
Summary
An improper input
validation vulnerability in the configuration service for processing encrypted
credential data has been identified in Tapo C200 v5. An attacker can send oversized crypted
ciphertext values that may trigger exception handling failures, due to insufficient
validation, causing the affected device to crash or restart.
Successful
exploitation may temporarily disrupt HTTPS management and monitoring
functionality, resulting in a denial-of-service (DoS) condition until the
service recovers.

Title
Unauthenticated Administrative Authentication Bypass via device_confirm Replay in TP-Link Tapo C120 and C200
Summary
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.

Title
Authenticated Stack-based Buffer Overflow in RTSP Authentication of Tapo C200
Summary
TP-Link Tapo C200 v5 contains a stack-based buffer overflow flaw in RTSP authentication handling due to improper validation of Authorization header field lengths, which can be triggered by a crafted authentication request.
Successful exploitation causes the affected RTSP core service process to crash and triggers an automatic system reboot, resulting in a denial of service (DoS) condition. This prevents legitimate users from accessing the camera’s live video stream or management interface until the service restarts.

Title
Denial-of-Service via Oversized Encrypted Credential Input in TP-Link Tapo C200
Summary
An improper input
validation vulnerability in the configuration service for processing encrypted
credential data has been identified in Tapo C200 v5. An attacker can send oversized crypted
ciphertext values that may trigger exception handling failures, due to insufficient
validation, causing the affected device to crash or restart.
Successful
exploitation may temporarily disrupt HTTPS management and monitoring
functionality, resulting in a denial-of-service (DoS) condition until the
service recovers.

Title
Unauthenticated Administrative Authentication Bypass via device_confirm Replay in TP-Link Tapo C120 and C200
Summary
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.

Title
Authenticated Stack-based Buffer Overflow in RTSP Authentication of Tapo C200
Summary
TP-Link Tapo C200 v5 contains a stack-based buffer overflow flaw in RTSP authentication handling due to improper validation of Authorization header field lengths, which can be triggered by a crafted authentication request.
Successful exploitation causes the affected RTSP core service process to crash and triggers an automatic system reboot, resulting in a denial of service (DoS) condition. This prevents legitimate users from accessing the camera’s live video stream or management interface until the service restarts.
