Description

AVTECH SECURITY Corporation DGM1104 FullImg-1015-1004-1006-1003 was discovered to contain an authenticated command injection vulnerability in the Machine.cgi endpoint. This vulnerability allows attackers to execute arbitrary commands via a crafted input.

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match
prevent

Directly prevents command injection in the Machine.cgi endpoint by enforcing validation of crafted inputs using organization-defined tools and procedures.

SI-2 Flaw Remediation good match
prevent

Requires timely identification, reporting, and correction of the specific authenticated command injection flaw (CVE-2025-57198) in Machine.cgi.

SI-9 Information Input Restrictions good match
prevent

Restricts classes of inputs to the Machine.cgi endpoint, blocking malicious crafted payloads that enable arbitrary command execution.

Security SummaryAI

CVE-2025-57198, published on 2025-12-03, is an authenticated command injection vulnerability (CWE-77) in the Machine.cgi endpoint of AVTECH SECURITY Corporation's DGM1104 FullImg-1015-1004-1006-1003. This flaw allows attackers to execute arbitrary commands via a crafted input. The vulnerability carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating high severity due to its potential for significant impact.

Exploitation requires low privileges, specifically authenticated access (PR:L), and can be performed remotely over the network (AV:N) with low complexity (AC:L) and no user interaction (UI:N). Successful attacks enable arbitrary command execution on the affected device, resulting in high confidentiality, integrity, and availability impacts (C:H/I:H/A:H) within the same security scope (S:U).
