CVE-2025-57200 identifies a command injection vulnerability in the AVTECH SECURITY Corporation DGM1104 device firmware versions FullImg-1015-1004-1006-1003. The vulnerability resides in the test_mail function, which is designed to test email configurations but improperly sanitizes input parameters. An authenticated attacker can leverage this flaw by submitting specially crafted inputs that inject arbitrary shell commands, which the device executes with the privileges of the affected service. This can lead to unauthorized command execution, potentially allowing attackers to manipulate device settings, exfiltrate data, disrupt operations, or pivot into internal networks. The requirement for authentication limits exploitation to users with valid credentials or those who have compromised such credentials. No CVSS score has been assigned yet, and no known public exploits or patches are currently available. The vulnerability was reserved in August 2025 and published in December 2025, indicating recent discovery. The lack of CWE classification and patch links suggests limited public technical details and mitigations at this time.

For European organizations, especially those deploying AVTECH DGM1104 devices in security, surveillance, or critical infrastructure environments, this vulnerability poses a significant risk. Successful exploitation could lead to unauthorized access and control over security devices, undermining physical security monitoring and potentially allowing attackers to disable alarms or cameras. This compromises confidentiality by exposing sensitive video or system data, integrity by allowing malicious configuration changes, and availability by enabling denial of service or device takeover. The requirement for authentication reduces the risk from external attackers but raises concerns about insider threats or credential compromise. The absence of patches increases exposure duration. Disruption of security devices can have cascading effects on organizational safety and compliance with European data protection and security regulations.

European organizations should immediately audit and restrict access to AVTECH DGM1104 device management interfaces, ensuring only trusted personnel have credentials. Implement multi-factor authentication where possible to reduce the risk of credential compromise. Monitor device logs and network traffic for unusual command execution patterns or configuration changes indicative of exploitation attempts. Network segmentation should isolate these devices from critical systems to limit lateral movement. Regularly check AVTECH's official channels for firmware updates or patches addressing this vulnerability and apply them promptly. Consider deploying intrusion detection systems tailored to detect command injection attempts. Additionally, conduct security awareness training to prevent credential phishing or insider misuse. If feasible, temporarily disable the test_mail function or related features until a patch is available.
