Can you explain this vulnerability to me?

This vulnerability exists in Ruckus Network Director (RND) versions prior to 4.5.0.54. The OVA appliance includes hardcoded credentials for the PostgreSQL database user named 'ruckus'. Because the PostgreSQL service is accessible over the network on TCP port 5432 by default, an attacker can remotely use these hardcoded credentials to authenticate.

Once authenticated, the attacker gains superuser access to the database, which enables them to create administrative users for the web interface, extract password hashes, and execute arbitrary operating system commands.

How can this vulnerability impact me? :

This vulnerability can have severe impacts including unauthorized administrative access to the Ruckus Network Director web interface, exposure of sensitive password hashes, and the ability for an attacker to execute arbitrary commands on the underlying operating system.

Such access could lead to full compromise of the network management system, potential disruption of network services, data theft, and further lateral movement within the affected environment.

How can this vulnerability be detected on my network or system? Can you suggest some commands?

This vulnerability can be detected by checking for the presence of the PostgreSQL service running on TCP port 5432 on Ruckus Network Director (RND) appliances with versions less than 4.5.0.54. Since the PostgreSQL service is accessible over the network, you can scan your network for open port 5432 on devices running RND.

• Use a network scanning tool such as nmap to detect open PostgreSQL ports: nmap -p 5432 <target-ip>
• Attempt to connect to the PostgreSQL service using the known hardcoded credentials to verify vulnerability: psql -h <target-ip> -p 5432 -U ruckus

Successful authentication with the hardcoded credentials indicates the system is vulnerable.

What immediate steps should I take to mitigate this vulnerability?

Immediate mitigation steps include restricting network access to the PostgreSQL service on TCP port 5432 to trusted hosts only, preventing remote attackers from connecting.

Additionally, upgrade Ruckus Network Director to version 4.5.0.54 or later where this vulnerability is fixed.

If upgrading immediately is not possible, consider changing the default PostgreSQL credentials and disabling remote access to the database service.
