CVE-2025-57198 identifies an authenticated command injection vulnerability in the AVTECH SECURITY Corporation DGM1104 device firmware versions FullImg-1015-1004-1006-1003. The vulnerability resides in the Machine.cgi endpoint, which processes user inputs without adequate sanitization or validation, allowing an attacker with legitimate access credentials to inject and execute arbitrary system commands remotely. This type of command injection (CWE-77) can lead to full system compromise, including unauthorized data access, modification, or destruction, and disruption of device availability. The vulnerability requires authentication but no user interaction, and the attack complexity is low, indicating that an attacker with valid credentials can exploit it with relative ease. The CVSS 3.1 base score of 8.8 reflects the high impact on confidentiality, integrity, and availability, with network attack vector and no user interaction needed. Although no known exploits are currently in the wild, the vulnerability's characteristics make it a significant risk for organizations using these devices, particularly in environments where AVTECH devices are deployed for security monitoring or access control. The lack of available patches at the time of publication necessitates immediate risk mitigation through compensating controls until official firmware updates are released.

The impact of CVE-2025-57198 on European organizations can be substantial, especially for those deploying AVTECH DGM1104 devices in critical infrastructure, corporate security, or public safety environments. Successful exploitation allows attackers to execute arbitrary commands with the privileges of the device, potentially leading to unauthorized access to sensitive surveillance data, manipulation of security controls, or complete device takeover. This compromises confidentiality by exposing sensitive video or sensor data, integrity by allowing tampering with device configurations or logs, and availability by enabling denial-of-service conditions or device bricking. Given the network-accessible nature of the vulnerability and the low complexity of exploitation, attackers could pivot from compromised devices to broader network segments, escalating risks to enterprise IT and OT environments. European organizations in sectors such as manufacturing, transportation, energy, and government services that rely on AVTECH security devices are particularly vulnerable. The absence of public exploits currently provides a window for proactive defense, but the high severity score underscores the urgency of addressing this vulnerability to prevent potential targeted attacks or widespread compromise.

1. Immediately audit and restrict access to AVTECH DGM1104 devices, ensuring that only authorized personnel have credentials and that strong, unique passwords are enforced. 2. Implement network segmentation to isolate these devices from critical network segments and limit exposure to potential attackers. 3. Monitor network traffic and device logs for unusual command execution patterns or authentication anomalies that could indicate exploitation attempts. 4. Disable or restrict access to the Machine.cgi endpoint if possible, or apply web application firewall (WAF) rules to detect and block command injection payloads targeting this endpoint. 5. Engage with AVTECH SECURITY Corporation to obtain and apply firmware updates or patches as soon as they become available. 6. Employ multi-factor authentication (MFA) for device management interfaces to reduce the risk of credential compromise. 7. Conduct regular vulnerability assessments and penetration testing focusing on IoT and security devices to identify and remediate similar vulnerabilities proactively. 8. Educate IT and security teams about this specific vulnerability and the importance of monitoring and rapid response to suspicious activities involving AVTECH devices.
