Authenticated Stack-based Buffer Overflow in ONVIF CreateUsers Service in TP-Link Tao C520WS
Summary
A stack‑based
buffer overflow vulnerability exists in Tapo C520WS v2 in the ONVIF CreateUsers service, where
the device fails to properly validate the number of XML user nodes during
request processing. An authenticated attacker can send a specially crafted
ONVIF request containing an excessive number of user entries to trigger memory
corruption.
Successful
exploitation may cause the ONVIF management service to terminate unexpectedly,
resulting in a denial‑of‑service (DoS) condition that disrupts device
configuration and management functions.

Title
Whitelist Validation Bypass in TP-Link Tapo C520WS
Summary
On Tapo
C520WS v2, restricted accounts (for example, hub users) are intended to execute
only a limited set of low‑sensitivity operations. Due to a logic flaw in the
device’s API authorization mechanism, an attacker can craft requests that
leverage legitimate “method mapping” behavior to bypass whitelist restrictions,
allowing restricted operations to be masked as permitted requests and executed.
Successful
exploitation may allow an attacker (with access to a restricted account) to
execute unauthorized sensitive operations.
Depending on the operation invoked, impact could include device
resets, unintended configuration changes, or disruption of normal operation,
leading to loss of availability and integrity of the device.

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
Stored Cross-Site Scripting (XSS) via Configuration File Import on TP-Link's TL-SG108PE
Summary
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.

Title
Bluetooth Communication Uses Unencrypted Transmission During Initial Setup on TP-Link's Tapo L535E, P300 and D100C
Summary
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.

Title
Improper Authentication Rate Limiting on TP-Link's Archer C64
Summary
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.

Title
Arbitrary Command Injection via Browser Developer Console in TP-Link Archer BE450 and BE7200
Summary
An authenticated command injection vulnerability exists in the Archer BE450 v1 and BE7200 v1 router that allows an administrator to execute arbitrary system commands through the web management interface. After successfully authenticating to the admin interface, an attacker can leverage the browser’s developer console by supplying a crafted input that is passed to backend system commands without adequate sanitization.
Successful exploitation enables execution of arbitrary commands with elevated privileges on the device, which may allow the attacker to start unauthorized services, modify system configuration, or otherwise fully compromise the router’s operating environment.

Title
Information Disclosure via Diagnostic Interface Due to Improper Input Validation on TP-Link's Archer AX72
Summary
In the web management interface of Archer AX72 (SG) v1, the network diagnostic feature improperly handles invalid user input, resulting in limited exposure of diagnostic command usage information.
An authenticated attacker with administrative privileges could exploit this issue to confirm the presence of the diagnostic utility and view its valid command-line syntax and options. The exposed information is limited in scope and does not include sensitive system data.

Title
Predictable Default Cryptographic Key Used for DES Encryption in TP-Link TL-WL841N
Summary
TP-Link TL-WR841N v13 uses DES-CBC encryption in the TDDPv2 debug protocol with a cryptographic key derived from default web management credentials, making the key predictable if device is left in default configuration. A network-adjacent attacker can exploit this weakness to gain unauthorized access to the protocol, read debug data, modify certain device configuration values, and trigger device reboot, resulting in loss of integrity and a denial-of-service condition.

Title
Use of weak cryptographic key in TP-Link Archer C7
Summary
Inadequate Encryption Strength vulnerability in TP-Link Archer C7 v5 and v5.8 (uhttpd modules) allows Password Recovery Exploitation. The web interface encrypts the admin password client-side using RSA-1024 before sending it to the router during login.
An adjacent attacker with the ability to intercept network traffic could potentially perform a brute-force or factorization attack against the 1024-bit RSA key to recover the plaintext administrator password, leading to unauthorized access and compromise of the device configuration. This issue affects Archer C7: through Build 20220715.

Title
Denial of Service via Path Expansion Overflow in HTTP Service in TP-Link Tapo C520WS
Summary
A denial-of-service vulnerability was identified in TP-Link Tapo C520WS v2.6 within the HTTP request path parsing logic. The implementation enforces length restrictions on the raw request path but does not account for path expansion performed during normalization. An attacker on the adjacent network may send a crafted HTTP request to cause buffer overflow and memory corruption, leading to system interruption or device reboot.

Title
Authentication Bypass in DS Configuration Service via HTTP Request Parsing Differential of TP-Link Tapo C520WS
Summary
An authentication bypass vulnerability within the HTTP handling of the DS configuration service in TP-Link Tapo C520WS v2.6 was identified, due to inconsistent parsing and authorization logic in JSON requests during authentication check. An unauthenticated attacker can append an authentication-exempt action to a request containing privileged DS do actions, bypassing authorization checks.
Successful exploitation allows unauthenticated execution of restricted configuration actions, which may result in unauthorized modification of device state.

Title
Heap-based Buffer Overflow Vulnerability Leading to Denial-of-Service in TP-Link Tapo C520WS
Summary
A heap-based buffer overflow vulnerability was identified in TP-Link Tapo C520WS v2.6 within the asynchronous parsing of local video stream content due to
insufficient alignment and validation of buffer boundaries when processing streaming inputs.An attacker
on the same network segment could trigger heap memory corruption conditions by
sending crafted payloads that cause write operations beyond allocated buffer
boundaries. Successful exploitation
causes a Denial-of-Service (DoS) condition, causing the device’s process to
crash or become unresponsive.

Title
Heap-based Buffer Overflow Vulnerability Leading to Denial-of-Service in TP-Link Tapo C520WS
Summary
A heap-based buffer overflow vulnerability was identified in TP-Link Tapo C520WS v2.6 within the HTTP parsing
loop
when appending segmented request bodies without
continuous write‑boundary verification, due to insufficient boundary validation when handling externally supplied HTTP input. An attacker
on the same network segment could trigger heap memory corruption conditions by
sending crafted payloads that cause write operations beyond allocated buffer
boundaries. Successful exploitation
causes a Denial-of-Service (DoS) condition, causing the device’s process to
crash or become unresponsive.

Title
Heap-based Buffer Overflow Vulnerability Leading to Denial-of-Service in TP-Link Tapo C520WS
Summary
A heap-based buffer overflow vulnerability was identified in TP-Link Tapo C520WS v2.6 in the HTTP POST body parsing logic due to missing validation of remaining buffer capacity after dynamic allocation, due to insufficient boundary validation when handling externally supplied HTTP input. An attacker
on the same network segment could trigger heap memory corruption conditions by
sending crafted payloads that cause write operations beyond allocated buffer
boundaries. Successful exploitation
causes a Denial-of-Service (DoS) condition, causing the device’s process to
crash or become unresponsive.
