CVE-2025-67304

Comprehensive Technical Analysis of CVE-2025-67304

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-67304 CVSS Score: 9.8

The vulnerability in Ruckus Network Director (RND) versions prior to 4.5.0.54 involves hardcoded credentials for the PostgreSQL database user. This issue is critical due to the potential for remote code execution (RCE) and unauthorized access to sensitive data. The CVSS score of 9.8 indicates a high severity, reflecting the ease of exploitation and the significant impact on confidentiality, integrity, and availability.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Network Access: The PostgreSQL service is accessible over the network on TCP port 5432, allowing remote attackers to attempt authentication.
• Hardcoded Credentials: The presence of hardcoded credentials for the PostgreSQL database user enables attackers to authenticate without needing to brute-force or guess the credentials.

Exploitation Methods:

• Remote Authentication: An attacker can use the hardcoded credentials to authenticate to the PostgreSQL database remotely.
• Superuser Access: Once authenticated, the attacker gains superuser access to the database, allowing them to perform various malicious activities.
• Administrative User Creation: The attacker can create administrative users for the web interface, gaining further control over the system.
• Password Hash Extraction: The attacker can extract password hashes, which can be used for further attacks or credential stuffing.
• Arbitrary OS Commands: With superuser access, the attacker can execute arbitrary OS commands, leading to RCE.

3. Affected Systems and Software Versions

Affected Software:

• Ruckus Network Director (RND) versions prior to 4.5.0.54

Affected Systems:

• Any system running the vulnerable versions of Ruckus Network Director with the default configuration that exposes the PostgreSQL service on TCP port 5432.

4. Recommended Mitigation Strategies

Immediate Mitigation:

• Upgrade Software: Upgrade to Ruckus Network Director version 4.5.0.54 or later, which addresses the vulnerability.
• Network Segmentation: Implement network segmentation to restrict access to the PostgreSQL service.
• Firewall Rules: Configure firewall rules to block unauthorized access to TCP port 5432.
• Credential Management: Change the default PostgreSQL credentials and ensure strong, unique passwords are used.

Long-Term Mitigation:

• Regular Patching: Implement a regular patching and update schedule for all software and systems.
• Monitoring and Logging: Enhance monitoring and logging to detect and respond to suspicious activities.
• Access Controls: Implement strict access controls and limit administrative privileges.

5. Impact on Cybersecurity Landscape

The presence of hardcoded credentials and the ease of remote exploitation highlight the importance of secure coding practices and regular security audits. This vulnerability underscores the need for:

• Secure Coding Practices: Avoiding hardcoded credentials and ensuring secure configuration of services.
• Regular Security Audits: Conducting regular security audits to identify and mitigate vulnerabilities.
• Incident Response: Having a robust incident response plan to quickly address and mitigate vulnerabilities.

6. Technical Details for Security Professionals

Vulnerability Details:

• Hardcoded Credentials: The PostgreSQL database user credentials are hardcoded in the Ruckus Network Director OVA appliance.
• Default Configuration: The PostgreSQL service is accessible over the network on TCP port 5432 by default.

Exploitation Steps:

1. Identify Target: Identify systems running vulnerable versions of Ruckus Network Director.
2. Access PostgreSQL: Use the hardcoded credentials to authenticate to the PostgreSQL database.
3. Gain Superuser Access: Once authenticated, gain superuser access to the database.
4. Execute Malicious Actions: Perform actions such as creating administrative users, extracting password hashes, and executing arbitrary OS commands.

Detection and Response:

• Network Monitoring: Monitor network traffic for unauthorized access attempts to TCP port 5432.
• Log Analysis: Analyze PostgreSQL logs for suspicious authentication attempts.
• Incident Response: Follow incident response procedures to contain and mitigate the impact of the vulnerability.

Conclusion: CVE-2025-67304 represents a critical vulnerability that can be exploited to gain unauthorized access and execute arbitrary commands. Immediate mitigation through software upgrades and network controls is essential to protect affected systems. Long-term, organizations should focus on secure coding practices, regular security audits, and robust incident response plans to enhance overall cybersecurity posture.
