A stored OS command injection vulnerability exists in the parent-control module of TP-Link Archer BE3600 V1. An authenticated adjacent attacker with administrative access may store a crafted profile name containing shell metacharacters, which is later processed unsafely during daily cloud report generation and may result in arbitrary command execution. Successful exploitation may allow command execution on the affected device with potential impact to device confidentiality, integrity, and availability.

An unauthenticated OS command injection vulnerability exists in the parental control functionality of Archer BE800 V1, BE3600 V1, and AX75 V1 due to improper filtering and neutralization of special characters in certain parameters. A LAN-based attacker can inject arbitrary commands and execute them with root privileges. Successful exploitation may result in complete device compromise and impact the confidentiality, integrity, and availability of the affected device and network traffic.

An authenticated command injection vulnerability in TP-Link Archer BE800 V1 allows an attacker with administrative access to execute arbitrary system commands with root privileges by injecting shell metacharacters via a VPN connection.  Successful exploitation may enable persistent backdoors, credential theft, LAN reconnaissance, and router-assisted attacks against connected devices.

The use of hard-coded cryptographic key vulnerability has been identified in the mesh functionality of Deco XE75 v3, XE5300 v3.6 and WE10800 v3.6.  A shared RSA-512 mesh group private key is present in the affected firmware and is used by the mesh protocol for node authentication.  An attacker who obtains the firmware image and has local network access may be able to authenticate as a mesh node without possessing a device-specific credential. Successful exploitation may allow an unauthenticated adjacent attacker to impersonate a trusted mesh node and bypass mesh node authentication, which may permit unauthorized changes to device or mesh configuration, affecting confidentiality, integrity and availability.

A stack-based out-of-bounds write vulnerability exists in the login request handling functionality of the administrative web interface of TP-Link TL-MR6400 v7 routers. An unauthenticated adjacent attacker can trigger the vulnerability by sending a specially crafted malformed HTTP request. Successful exploitation may cause the web service process to crash, resulting in a denial-of-service condition and temporary loss of access to the router's web management interface.

A NULL pointer dereference vulnerability exists in the HTTP request parsing functionality of  TL-MR6400 v7. An unauthenticated remote attacker can trigger the vulnerability by sending a specially crafted HTTP request containing a malformed session cookie header. Successful exploitation may cause the HTTP service process to crash, resulting in a denial-of-service condition and temporary loss of management or CGI functionality until service recovery.

A stack-based buffer overflow vulnerability exists in the firmware update functionality of TL-MR6400 v7 due to unsafe processing of attacker-controlled metadata within a firmware image. Successful exploitation may allow an authenticated attacker to trigger memory corruption and execute arbitrary code on 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.

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.

Certain web interface components in affected TP-Link Aginet devices do not validate and sanitize user-supplied input properly before passing it to system-level command execution functions.  An authenticated adjacent attacker may inject specially crafted input to execute arbitrary operation system commands with elevated privileges. Successful exploitation may allow execution of arbitrary system commands, potentially leading to full device compromise.

In affected TP-Link Aginet devices, use of hardcoded cryptographic keys embedded in the firmware to protect sensitive configuration data may allow an attacker who has access to device storage to recover the keys and decrypt stored data. Successful exploitation may allow access to decrypted sensitive configuration data, including credentials and service-related information.

In affected TP-Link Aginet devices, insufficient authorization validation allows authenticated low-privileged users to execute higher-privileged operations. An attacker may perform administrative actions such as creating privileged accounts or modifying critical configuration settings.

The affected TP-Link Aginet devices contain a flaw in the web management interface where authentication checks are not consistently enforced on certain endpoints. An attacker can send specially crafted requests to bypass authentication and directly invoke privileged functionality without valid credentials. This issue arises from improper enforcement of access control mechanisms on sensitive operations. Successful exploitation may allow an unauthenticated attacker to execute privileged operations and gain full control of the device.
