CVE-2026-19683

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.

Summary
  • (es) Una vulnerabilidad existe en la funcionalidad de DNS Dinámico (DDNS) de los Gateways TP-Link Omada. Durante la comunicación con un servicio DDNS de terceros, las credenciales de autenticación se transmiten a través de un canal no cifrado. Un atacante que puede observar o manipular el tráfico entre un dispositivo afectado y el servicio DDNS puede obtener información de autenticación sensible o interferir con las operaciones de actualización de DDNS. La explotación requiere que el DDNS esté configurado, comunicación con un servicio DDNS externo, y visibilidad o control del atacante de la ruta de red relevante. La explotación exitosa puede resultar en la divulgación de credenciales de cuenta DDNS, acceso no autorizado a la funcionalidad de gestión de DDNS, o la modificación de registros DNS asociados con la implementación afectada.
