SuperMicro Device Uses Default SSH Host Key

critical Nessus Plugin ID 71533

Synopsis

The remote device is using the default SSH host key for this service, whose private key is public knowledge.

Description

The SSH host key used by the remote host has not been changed from the default host key that is hardwired into the firmware. The private key corresponding to this host key is shared across all devices running the same firmware, meaning that the remote host's key certificate cannot be trusted.

Solution

Configure the device to use a device-specific host key.
