The DDNS update function in ADM fails to properly validate the hostname of the DDNS server's TLS/SSL certificate. Although the connection uses HTTPS, an improper validated TLS/SSL certificates allows a remote attacker can intercept the communication to perform a Man-in-the-Middle (MitM) attack, which may obtain the sensitive information of DDNS updating process, including the user's account email, MD5 hashed password, and device serial number.This issue affects ADM: from 4.1.0 through 4.3.3.ROF1, from 5.0.0 through 5.1.1.RCI1.

Summary
  • (es) La función de actualización de DDNS en ADM no valida correctamente el nombre de host del certificado TLS/SSL del servidor DDNS. Aunque la conexión utiliza HTTPS, un certificado TLS/SSL incorrectamente validado permite a un atacante remoto interceptar la comunicación para realizar un ataque man-in-the-middle (MitM), lo que puede obtener la información sensible del proceso de actualización de DDNS, incluyendo el correo electrónico de la cuenta del usuario, la contraseña con hash MD5 y el número de serie del dispositivo. Este problema afecta a ADM: desde 4.1.0 hasta 4.3.3.ROF1, desde 5.0.0 hasta 5.1.1.RCI1.
