CVE-2026-24932
An improper certificate validation vulnerability was found in ADM while updating the DDNS settings.
Description

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.
