Description

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.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
