Tp-Link: Security Vulnerabilities
An unauthenticated attacker with network access to the captive portal service of an affected device can terminate active captive portal sessions, including forcing logout of specific users or clearing all active sessions. Affected users must re-authenticate to regain access.
Successful exploitation may allow termination of individual or all active captive portal sessions, causing temporary service disruption and requiring users to re-authenticate.

A pre-authentication OS command injection vulnerability has been identified in Omada gateways configured to operate as an OpenVPN Server due to insufficient validation of client-supplied data during OpenVPN connection establishment. An unauthenticated remote attacker may provide specially crafted input influencing backend command execution logic before authentication completes. Exploitation requires the OpenVPN Server feature to be enabled, VPN service reachable by the attacker and attacker to be able to initiate an OpenVPN connection attempt.
Successful exploitation may allow arbitrary command execution, potentially
leading to full compromise of the affected device.

A vulnerability exists in the Dynamic DNS (DDNS) functionality of TP-Link Omada Gateways. During communication with a third-party DDNS service, authentication credentials are transmitted over an unencrypted channel. An attacker who can observe or manipulate traffic between an affected device and the DDNS service may obtain sensitive authentication information or interfere with DDNS update operations. Exploitation requires DDNS to be configured, communication with an external DDNS service, and attacker visibility or control of the relevant network path.
Successful exploitation may result in disclosure of DDNS account credentials, unauthorized access to DDNS management functionality, or modification of DNS records associated with the affected deployment.

An
unauthenticated denial-of-service vulnerability was identified in TP-Link TL-MR100 v3.2, TL-MR150 v3.2, TL-MR6400 v8.0 and Archer MR600 v2, due to improper handling of exceptional request conditions
that may lead to a NULL pointer dereference.
A remote attacker on an adjacent network can send a specially crated
HTTP request to trigger a crash of the HTTP service process.
Successful
exploitation may cause the HTTP service to crash, making the web management
interface and HTTP-dependent functionality temporarily unavailable.

An OS command injection vulnerability exists in the web management interface of Archer C20 v6 firmware when processing certain WAN-related configuration operations. An authenticated administrator may exploit insufficient input validation to execute arbitrary system commands, potentially resulting in full device compromise.
Successful exploitation may allow arbitrary command execution with elevated privileges, compromising the confidentiality, integrity, and availability of the affected device and network traffic passing through it.

Tapo C100/C101 V5 contains a null pointer dereference vulnerability in the RTSP service. An attacker on the local network can send specially crafted requests that cause the service to dereference an invalid pointer, resulting in a service crash and device reboot. Successful exploitation can disrupt live video streaming functionality and cause a temporary denial-of-service condition.

Tapo
C100/C101 V5 contains a heap-based buffer overflow vulnerability in the RTSP
service. An authenticated attacker on the local network can send specially
crafted RTSP frame data containing oversized length values, resulting in
out-of-bounds heap writes.
Successful
exploitation can crash the RTSP service and trigger a device reboot, resulting
in a temporary denial-of-service condition.

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.

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.

The web
interface of the affected
device relies on the HTTP referrer header as part of
request validation. Requests containing empty Referer value, or omitting
the Referer header entirely, may be accepted and processed due to insufficient
validation logic.
Successful exploitation may allow an adjacent attacker with access to the web management
interface to obtain device configuration details and other sensitive
information.
