Summary

The vulnerability in Eufy Homebase 2 firmware before version 3.3.4.1h causes the dedicated wireless network for its ecosystem to generate the WPA2-PSK key solely based on the serial number. This flaw allows offline brute-force cracking of the key within seconds, enabling an attacker in proximity to gain unauthorized access to the end user's primary network.

Risk Assessment

The organization faces the risk of an attacker in proximity to the dedicated Eufy network gaining control over the primary network, potentially leading to data theft, malware infection, or further attacks on network resources.

Recommendation

Immediately update the Eufy Homebase 2 firmware to version 3.3.4.1h or later, and consider changing default wireless network settings and implementing additional security measures such as IoT network isolation.

Original NVD description (English source)

The Eufy Homebase 2 before firmware version 3.3.4.1h creates a dedicated wireless network for its ecosystem, which serves as a proxy to the end user's primary network. The WPA2-PSK generation of this dedicated network is flawed and solely based on the serial number. Due to the flawed generation process, the WPA2-PSK can be brute forced offline within seconds. This vulnerability allows an attacker in proximity to the dedicated wireless network to gain unauthorized access to the end user's primary network. The only requirement of the attack is proximity to the dedicated wireless network.
