CVE-2025-67305 affects RUCKUS Network Director (RND) versions earlier than 4.5.0.56 and stems from the inclusion of hardcoded SSH keys within the OVA appliance for the postgres user. These SSH keys are identical across all deployments, meaning any attacker who can reach the network interface of the appliance can use these keys to authenticate via SSH without needing a password. Once authenticated, the attacker gains superuser privileges on the PostgreSQL database, which is the backend for RND. This level of access allows the attacker to manipulate database contents, including creating new administrative users for the RND web interface, thereby gaining persistent and elevated control over the network management system. The vulnerability does not require user interaction or prior authentication beyond network access, making it highly exploitable in exposed environments. The flaw arises from poor key management and insecure default configurations in the appliance image. Although no public exploits have been reported, the potential for lateral movement, data exfiltration, and network compromise is high. The vulnerability highlights the risks of hardcoded credentials and the need for unique, securely managed keys in network appliances.

The impact of CVE-2025-67305 is severe for organizations using vulnerable versions of RUCKUS Network Director. Attackers gaining superuser access to the PostgreSQL database can fully control the network management system, including creating or modifying administrative accounts, altering network configurations, and potentially deploying further malicious activities within the managed network. This can lead to unauthorized access to sensitive network infrastructure, disruption of network services, and exposure of confidential data. The vulnerability undermines the integrity, confidentiality, and availability of the network management environment. Organizations relying on RND for managing wireless and wired network devices face risks of persistent compromise and lateral movement within their networks. The ease of exploitation without authentication or user interaction increases the likelihood of attacks, especially in environments where the appliance is exposed to untrusted networks or insufficiently segmented internal networks.

To mitigate CVE-2025-67305, organizations should immediately upgrade RUCKUS Network Director to version 4.5.0.56 or later, where the hardcoded SSH key issue is resolved. If upgrading is not immediately possible, restrict network access to the RND appliance by implementing strict network segmentation and firewall rules to limit SSH access only to trusted administrators and management networks. Disable SSH access to the postgres user or replace the hardcoded keys with unique, securely generated SSH keys per deployment. Conduct thorough audits of existing administrative accounts and database users to detect unauthorized additions or modifications. Monitor network traffic and logs for unusual SSH authentication attempts or database activity. Additionally, implement multi-factor authentication for web interface access and ensure that all default credentials and keys are replaced during deployment. Regularly review and update security configurations for network management appliances to prevent similar issues.
