CVE-2025-57201 is an authenticated command injection vulnerability identified in the SMB server functionality of AVTECH SECURITY Corporation's DGM1104 FullImg-1015-1004-1006-1003 device. This vulnerability arises when the SMB server improperly sanitizes user input, allowing an attacker who has valid authentication credentials to inject and execute arbitrary system commands. The exploitation requires authentication, which limits exposure to attackers who can gain or have legitimate access, but once exploited, it can lead to full system compromise including unauthorized control over the device. The affected device is likely used in security and surveillance contexts, given AVTECH's product portfolio. No CVSS score has been assigned yet, and no public exploits are known, but the vulnerability's nature suggests a high risk due to the ability to execute arbitrary commands remotely. The lack of patch links indicates that a fix may not yet be available, emphasizing the need for interim mitigations. The vulnerability was reserved in August 2025 and published in December 2025, indicating recent discovery. The SMB protocol is commonly used in networked environments, increasing the attack surface if devices are exposed or improperly segmented. This vulnerability could be leveraged to disrupt security operations, exfiltrate data, or pivot to other network assets.

For European organizations, the impact of CVE-2025-57201 could be significant, especially for those relying on AVTECH devices for physical security and surveillance. Successful exploitation could lead to unauthorized command execution, resulting in device manipulation, data theft, or denial of service. This could disrupt security monitoring, compromise sensitive video feeds, or allow attackers to establish persistence within the network. The requirement for authentication reduces the risk from external attackers but raises concerns about insider threats or credential compromise. The vulnerability could also be used as a foothold for lateral movement within corporate networks. Given the critical role of security devices, any compromise could have cascading effects on organizational security posture and compliance with data protection regulations such as GDPR. Operational continuity in sectors like transportation, government facilities, and critical infrastructure could be jeopardized.

Organizations should implement the following specific mitigations: 1) Immediately restrict SMB server access on AVTECH devices to trusted internal networks and block SMB traffic from untrusted sources. 2) Enforce strong authentication policies, including multi-factor authentication where possible, to reduce the risk of credential compromise. 3) Monitor SMB traffic for unusual or malformed requests that could indicate exploitation attempts. 4) Segment networks to isolate security devices from general IT infrastructure, limiting lateral movement opportunities. 5) Maintain rigorous credential management and audit logs to detect unauthorized access. 6) Engage with AVTECH for firmware updates or patches and plan prompt deployment once available. 7) Consider temporary disabling of SMB services on affected devices if operationally feasible until patches are applied. 8) Conduct regular vulnerability assessments and penetration testing focused on security devices to identify similar risks.
