CVE-2025-34042 is a critical OS command injection vulnerability affecting the Beward N100 IP Camera firmware version M2.1.6.04C014. This vulnerability arises from improper neutralization of special elements in the ServerName and TimeZone parameters on the servetest CGI page. An authenticated attacker who can access the camera's web interface can inject arbitrary system commands through these parameters. These inputs are embedded unsafely into backend system calls without adequate input sanitization or validation, allowing execution of arbitrary commands with root privileges. The vulnerability is classified under CWE-78 (Improper Neutralization of Special Elements used in an OS Command) and CWE-20 (Improper Input Validation). The CVSS v4.0 score is 9.4 (critical), reflecting the vulnerability's high impact and ease of exploitation. No user interaction or additional authentication beyond web interface access is required, and exploitation leads to full system compromise. Although no public exploits have been reported yet, the severity and nature of the flaw make it a high-risk target for attackers aiming to gain persistent control over IP cameras, which are often deployed in sensitive environments for surveillance and security monitoring.

For European organizations, this vulnerability poses significant risks, especially for entities relying on Beward N100 IP Cameras for physical security, such as government facilities, critical infrastructure, transportation hubs, and corporate offices. Exploitation can lead to full system compromise, allowing attackers to execute arbitrary commands with root privileges. This can result in unauthorized surveillance, data exfiltration, lateral movement within networks, and potential disruption of security monitoring capabilities. Given the root-level access, attackers could also deploy malware or use compromised devices as footholds for broader network attacks. The impact extends to privacy violations and potential breaches of GDPR regulations if personal data captured by cameras is accessed or manipulated. The lack of known public exploits currently provides a window for mitigation, but the critical severity demands immediate attention to prevent exploitation.

1. Immediate firmware update: Organizations should monitor Beward's official channels for a security patch addressing this vulnerability and apply it promptly once available. 2. Access control hardening: Restrict access to the camera's web interface to trusted networks and users only, using network segmentation and firewall rules to limit exposure. 3. Strong authentication: Enforce strong, unique credentials for camera web interfaces and consider multi-factor authentication if supported. 4. Input validation proxy: Deploy web application firewalls (WAFs) or network intrusion prevention systems (IPS) capable of detecting and blocking command injection patterns targeting the servetest CGI page parameters. 5. Network monitoring: Implement continuous monitoring for unusual command execution or network traffic originating from IP cameras. 6. Device inventory and replacement: Identify all deployed Beward N100 IP Cameras running the vulnerable firmware and plan for replacement or isolation if patching is delayed. 7. Disable unnecessary services: If possible, disable or restrict access to the servetest CGI page or related services that expose vulnerable parameters. 8. Incident response readiness: Prepare for potential compromise scenarios by having incident response plans tailored to IoT and IP camera devices.
