Some Huawei storage products have a hardcoded SSH key vulnerability. Different nodes of the devices use SSH to encrypt communication data and authenticate each other based on public and private keys. Since the SSH public and private keys are hardcoded, an attacker may obtain the keys and log in to such a device through SSH. (Vulnerability ID: HWPSIRT-2016-05005)
The attacker can log in to the device through SSH. However, the attacker cannot launch remote attacks, because only a limited number of internal IP addresses can be used for communication between different nodes.
The attacker has obtained the public and private keys.
2. Attacking procedure:
The attacker uses the obtained public and private keys to log in to the device through SSH and intercept and interrupt communication between different nodes of the device.
