EUVD-2025-29048

Comprehensive Technical Analysis of EUVD-2025-29048

1. Vulnerability Assessment and Severity Evaluation

The EUVD entry EUVD-2025-29048 describes multiple critical vulnerabilities in the Evertz SDVN 3080ipx-10G High Bandwidth Ethernet Switching Fabric for Video Application. The vulnerabilities include:

• CVE-2025-4009: Command injection in feature-transfer-import.php.
• CVE-2025-10364: Command injection in feature-transfer-export.php.
• CVE-2025-10365: Authentication bypass flaw.

These vulnerabilities allow remote unauthenticated attackers to execute arbitrary commands with elevated privileges (root) on affected devices. The CVSS Base Score of 9.3 indicates a critical severity level, reflecting the high potential for significant business impact, including interruption of media streaming, modification of media content, and alteration of closed captions.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Remote Command Injection: Attackers can exploit the command injection vulnerabilities in the web management interface endpoints (feature-transfer-import.php and feature-transfer-export.php) to execute arbitrary commands on the device.
• Authentication Bypass: The flaw in the authentication mechanism allows attackers to bypass authentication controls, gaining unauthorized access to the web management interface.

Exploitation Methods:

• Command Injection: By crafting malicious input to the vulnerable endpoints, attackers can inject and execute arbitrary commands, potentially leading to full system compromise.
• Authentication Bypass: Exploiting the authentication bypass vulnerability, attackers can gain administrative access to the device without valid credentials.

3. Affected Systems and Software Versions

The vulnerabilities affect the following Evertz products:

• 3080ipx-10G
• cVIP
• CC Access Server
• 5782XPS-APP-4E
• MViP-II
• 7890IXG

All versions of these products are potentially affected unless specifically patched or updated to address these vulnerabilities.

4. Recommended Mitigation Strategies

Immediate Mitigation:

• Network Segmentation: Isolate affected devices from the broader network to limit potential attack vectors.
• Access Controls: Implement strict access controls and monitoring to detect and prevent unauthorized access attempts.
• Disable Unnecessary Services: Disable the web management interface if not in use or restrict access to trusted IP addresses.

Long-Term Mitigation:

• Patch Management: Apply vendor-provided patches or updates as soon as they become available.
• Regular Audits: Conduct regular security audits and vulnerability assessments to identify and address potential security weaknesses.
• Intrusion Detection/Prevention Systems (IDPS): Deploy IDPS to monitor and block suspicious activities.

5. Impact on European Cybersecurity Landscape

The vulnerabilities in Evertz devices pose a significant risk to the European cybersecurity landscape, particularly in sectors relying on high bandwidth Ethernet switching for video applications, such as media and broadcasting. The potential for unauthorized access and command execution could lead to:

• Service Disruption: Interruption of media streaming services.
• Data Integrity: Modification of media content and closed captions.
• Reputation Damage: Compromise of media integrity leading to loss of trust and potential legal repercussions.

6. Technical Details for Security Professionals

Vulnerability Details:

• CVE-2025-4009: Command injection in feature-transfer-import.php allows attackers to inject and execute arbitrary commands.
• CVE-2025-10364: Command injection in feature-transfer-export.php allows similar exploitation.
• CVE-2025-10365: Authentication bypass flaw enables attackers to gain administrative access without valid credentials.

Exploitation Steps:

1. Identify Target: Locate the Evertz device with the web management interface exposed on port 80.
2. Authentication Bypass: Exploit the authentication bypass vulnerability to gain access.
3. Command Injection: Craft and send malicious input to the vulnerable endpoints to execute arbitrary commands.

Detection and Monitoring:

• Log Analysis: Monitor web server logs for suspicious activities and unauthorized access attempts.
• Network Traffic Analysis: Use network monitoring tools to detect unusual traffic patterns indicative of command injection attempts.
• Behavioral Analysis: Implement behavioral analysis tools to identify deviations from normal device behavior.

Conclusion: The vulnerabilities described in EUVD-2025-29048 represent a critical risk to organizations using Evertz devices. Immediate and long-term mitigation strategies are essential to protect against potential exploitation. Regular security assessments and prompt patching are crucial to maintaining the integrity and availability of media streaming services.
