EUVD-2025-19212

Comprehensive Technical Analysis of EUVD-2025-19212

1. Vulnerability Assessment and Severity Evaluation

The vulnerability EUVD-2025-19212, also known as CVE-2025-34042, is an authenticated command injection vulnerability in the Beward N100 IP Camera firmware version M2.1.6.04C014. The vulnerability allows an attacker with access to the web interface to inject arbitrary system commands via the ServerName and TimeZone parameters in the servetest CGI page. These parameters are unsafely embedded into backend system calls without proper input sanitization, leading to remote code execution (RCE) with root privileges.

Severity Evaluation:

• CVSS Base Score: 9.4
• CVSS Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H

The high base score indicates a critical vulnerability due to the potential for complete system compromise, including confidentiality, integrity, and availability impacts.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Authenticated Access: An attacker must have valid credentials to access the web interface of the Beward N100 IP Camera.
• Command Injection: The attacker can inject malicious commands into the ServerName and TimeZone parameters, which are then executed by the system with root privileges.

Exploitation Methods:

• Direct Exploitation: An attacker can directly input malicious commands through the web interface.
• Automated Scripts: Attackers can use automated scripts to exploit the vulnerability, especially if they have a list of default or weak credentials.

3. Affected Systems and Software Versions

Affected Systems:

• Beward N100 IP Camera

Affected Software Versions:

• Firmware version M2.1.6.04C014

4. Recommended Mitigation Strategies

Immediate Mitigation:

• Update Firmware: Immediately update the firmware to a version that addresses this vulnerability.
• Change Default Credentials: Ensure that default credentials are changed to strong, unique passwords.
• Network Segmentation: Isolate IP cameras on a separate network segment to limit potential attack vectors.
• Access Control: Implement strict access controls to limit who can access the web interface.

Long-Term Mitigation:

• Regular Patching: Establish a regular patching and update schedule for all IoT devices.
• Monitoring: Implement continuous monitoring and logging to detect any suspicious activities.
• Security Training: Provide training for staff on the importance of cybersecurity best practices.

5. Impact on European Cybersecurity Landscape

The vulnerability poses a significant risk to organizations and individuals using the Beward N100 IP Camera, particularly in Europe. The potential for remote code execution with root privileges can lead to severe breaches, including data theft, unauthorized surveillance, and further compromise of connected systems. This underscores the need for robust cybersecurity measures for IoT devices, which are increasingly integrated into critical infrastructure and personal environments.

6. Technical Details for Security Professionals

Vulnerability Details:

• Vulnerable Parameters: ServerName and TimeZone in the servetest CGI page.
• Input Sanitization: The parameters are not properly sanitized, allowing for command injection.
• Execution Context: Commands are executed with root privileges, leading to full system compromise.

Exploitation Steps:

1. Access Web Interface: Log in to the web interface of the Beward N100 IP Camera.
2. Inject Commands: Input malicious commands into the ServerName and TimeZone parameters.
3. Execute Commands: The backend system calls will execute the injected commands with root privileges.

Detection and Response:

• Log Analysis: Monitor logs for unusual command executions or access patterns.
• Intrusion Detection Systems (IDS): Deploy IDS to detect and alert on suspicious activities.
• Incident Response Plan: Have a predefined incident response plan to quickly address any detected exploitation attempts.
