Tp-Link: Security Vulnerabilities
An authenticated stack-based buffer overflow vulnerability exists in the web management interface of TP-Link TL-WR841N v14. A remote authenticated attacker can send crafted HTTP requests to cause the embedded web server to overflow a stack buffer, resulting in a crash of the affected process.
Successful exploitation results in a denial-of-service condition, causing the device to crash and automatically reboot.

A denial-of-service (DoS) vulnerability has been identified in Tapo C200 v3 in the network packet handling logic due to improper handling of IPv4 fragmented packets. An unauthenticated adjacent attacker can send crafted packets to cause excessive resource consumption, leading to instability of the device.Successful exploitation can remotely trigger a temporary denial-of-service condition, causing the camera to become unresponsive and resulting in intermittent loss of video monitoring and recording.

An
authenticated format string vulnerability exists in the ONVIF service of Tapo
C110 v2 due to improper handling of user-controlled input. Externally controlled data is interpreted as
a format string, which can be used to manipulate stack memory, including
control flow data such as return addresses.
A remote
authenticated attacker may redirect execution flow to existing internal
functions, triggering an unauthorized factory reset, leading to loss of
configuration, deletion of stored credentials and service disruption.

A denial-of-service
vulnerability exists in the RTSP server component of TP-Link Tapo C520WS v2 due to improper handling of
syntactically invalid input. Crafted inputs
can trigger a processing error, causing the RTSP service to enter non-responsive
state.
Successful
exploitation may cause the RTSP in a denial-of-service condition.

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.

A stored
cross-site scripting (XSS) vulnerability has been identified in the web
management interface of TP-Link's TL-SG108PE v5 switch due to improper sanitation of the SYSNAM
configuration parameter during configuration file import. An attacker with
administrator access can inject malicious script into the device configuration,
which may be stored and executed in the administrator’s browser when the
affected interface is viewed.
Successful
exploitation may allow session cookie theft, unauthorized configuration
changes, or access to sensitive information exposed through the management
interface.

TP-Link has identified a vulnerability in Tapo L535E v1.0 and v3.0, Tapo P300 v1.0, and Tapo D100C v1.0, where Bluetooth communication during the initial setup phase is transmitted in cleartext without encryption. Bluetooth is only used during initialization.
An attacker within the Bluetooth range could exploit this behavior using Bluetooth sniffing or man-in-the-middle techniques, which may allow eavesdropping on Bluetooth communication, manipulate transmitted setup data and potentially gain unauthorized control of the device during initialization.

Due to improper enforcement of authentication rate-limiting on a debug SSH service in Archer C64 v1, the SSH service allows unlimited authentication attempts and uses the same credentials as the web interface. This enables an attacker to brute-force valid credentials via SSH.
Successful exploitation could allow an attacker with adjacent network access to obtain administrative credentials through unrestricted authentication attempts and subsequently gain full administrative access to the device, impacting system confidentiality, integrity, and availability.
