CVE-2025-46120

Comprehensive Technical Analysis of CVE-2025-46120

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-46120 CVSS Score: 9.8

The vulnerability in question is a path-traversal flaw in the web interface of CommScope Ruckus Unleashed and Ruckus ZoneDirector. This flaw allows a remote unauthenticated attacker to execute attacker-supplied EJS (Embedded JavaScript) templates outside permitted directories. The severity of this vulnerability is rated at 9.8 on the CVSS scale, indicating a critical risk. The high score is due to the potential for unauthenticated remote code execution, which can lead to full system compromise.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Remote Unauthenticated Access: The attacker can exploit this vulnerability without needing any credentials, making it highly accessible.
• FTP Upload: The attacker can upload malicious EJS templates via FTP, which the server will then execute.

Exploitation Methods:

• Path Traversal: The attacker can manipulate file paths to access and execute EJS templates outside the intended directories.
• Template Injection: By uploading a crafted EJS template, the attacker can inject malicious code that will be executed by the server.

3. Affected Systems and Software Versions

Affected Products:

• CommScope Ruckus Unleashed: Versions prior to 200.15.6.212.27 and 200.18.7.1.323
• Ruckus ZoneDirector: Versions prior to 10.5.1.0.282

Impacted Components:

• The web interface of the affected products, specifically the component handling EJS templates.

4. Recommended Mitigation Strategies

Immediate Actions:

• Patching: Upgrade to the latest versions of CommScope Ruckus Unleashed (200.15.6.212.27 or 200.18.7.1.323) and Ruckus ZoneDirector (10.5.1.0.282) to mitigate the vulnerability.
• Disable FTP: If possible, disable FTP access to prevent unauthorized uploads.
• Network Segmentation: Implement network segmentation to limit the exposure of vulnerable systems.

Long-Term Strategies:

• Regular Security Audits: Conduct regular security audits and vulnerability assessments.
• Access Controls: Implement strict access controls and monitor for unauthorized access attempts.
• Intrusion Detection Systems (IDS): Deploy IDS to detect and respond to suspicious activities.

5. Impact on Cybersecurity Landscape

The discovery of this vulnerability highlights the ongoing challenge of securing network devices, particularly those with web interfaces. The potential for unauthenticated remote code execution underscores the need for robust security measures in network infrastructure. This vulnerability can be exploited to gain unauthorized access, escalate privileges, and execute arbitrary code, posing a significant risk to organizations relying on these devices for network management.

6. Technical Details for Security Professionals

Vulnerability Details:

• Path Traversal: The flaw allows an attacker to traverse directories and access files outside the intended scope.
• EJS Template Execution: The server executes EJS templates, which can be manipulated to run arbitrary code.

Detection and Response:

• Log Analysis: Monitor logs for unusual file access patterns and EJS template execution.
• Incident Response: Develop an incident response plan to quickly identify and mitigate any exploitation attempts.
• Threat Intelligence: Leverage threat intelligence feeds to stay informed about emerging threats and exploitation techniques.
