CVE-2025-57200 is a command injection vulnerability identified in the firmware of AVTECH SECURITY Corporation's DGM1104 device, specifically in the test_mail function. This vulnerability allows an authenticated attacker to inject and execute arbitrary system commands by crafting malicious input parameters sent to the test_mail function. The vulnerability is classified under CWE-77 (Improper Neutralization of Special Elements used in a Command), indicating that user-supplied input is not properly sanitized before being passed to system-level command execution functions. The CVSS v3.1 base score is 6.5, reflecting a medium severity level. The vector string (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N) indicates that the attack can be performed remotely over the network with low attack complexity, no privileges required beyond authentication, and no user interaction needed. The impact affects confidentiality and integrity but does not affect availability. No patches or firmware updates have been published yet, and no known exploits have been reported in the wild. The vulnerability requires the attacker to have valid authentication credentials, which limits the attack surface but still poses a significant risk if credentials are compromised or weak. The affected versions are not explicitly listed, but the firmware versions mentioned (FullImg-1015-1004-1006-1003) are implicated. This vulnerability could be leveraged to gain unauthorized control over the device, potentially leading to data exfiltration, manipulation of device settings, or pivoting within the network.

For European organizations, the impact of CVE-2025-57200 could be significant, especially for those relying on AVTECH DGM1104 devices for security monitoring or access control. Successful exploitation could allow attackers to execute arbitrary commands on these devices, leading to unauthorized access to sensitive information, manipulation of device configurations, or use of the device as a foothold for further network intrusion. Confidentiality breaches could expose personal or corporate data, while integrity compromises could disrupt security monitoring or control functions. Although availability is not directly impacted, the indirect effects of compromised devices could degrade overall security posture. Organizations in sectors such as critical infrastructure, manufacturing, and corporate security that deploy these devices are particularly at risk. The requirement for authentication reduces the risk somewhat but does not eliminate it, especially if credential management is weak. The absence of known exploits in the wild provides a window for mitigation before active exploitation occurs.

1. Immediately audit and strengthen authentication mechanisms for AVTECH DGM1104 devices, including enforcing strong, unique passwords and multi-factor authentication where possible. 2. Limit network access to the management interfaces of these devices by implementing network segmentation and firewall rules restricting access to trusted administrators only. 3. Monitor device logs and network traffic for unusual command execution patterns or unauthorized access attempts. 4. Disable or restrict the use of the test_mail function if it is not essential for operations to reduce the attack surface. 5. Engage with AVTECH SECURITY Corporation to obtain information on forthcoming patches or firmware updates addressing this vulnerability and apply them promptly once available. 6. Implement strict credential management policies, including regular password changes and monitoring for credential compromise. 7. Conduct penetration testing and vulnerability assessments focusing on these devices to identify potential exploitation paths. 8. Educate administrators about the risks of this vulnerability and the importance of securing device access.
