In RUCKUS Network Director (RND) < 4.5.0.56, the OVA appliance contains hardcoded SSH keys for the postgres user. These keys are identical across all deployments, allowing an attacker with network access to authenticate via SSH without a password. Once authenticated, the attacker can access the PostgreSQL database with superuser privileges, create administrative users for the web interface, and potentially escalate privileges further.
Weakness
The product uses a hard-coded, unchangeable cryptographic key.
