🤖 AI Analysis

How it works

The manufacturer embedded a predefined, known default password in the firmware assigned to a built-in administrative account. The device does not enforce changing this password during initial startup or configuration. An attacker, knowing the default login credentials, can directly authenticate to the management interface over the network without needing to obtain any information or interact with the user.

Impact

An attacker gains authenticated access to the device management interface, which allows them to completely reconfigure the router, intercept network traffic, and potentially use the device as an entry point into a protected network.

Mitigation & patch

The default password on the device management interface should be immediately changed to a unique and strong password. Access to the management interface should also be restricted exclusively to trusted IP addresses or network segments. It is recommended to check for updated firmware availability from the manufacturer at https://www.tendacn.com/product/W30E and implement it immediately if available.
