Overview
CVE-2025-57201 describes a high-severity command injection vulnerability found in AVTECH SECURITY Corporation’s DGM1104 devices, specifically affecting the FullImg-1015-1004-1006-1003 firmware. This vulnerability resides within the SMB server function of the device. A successful exploit of this vulnerability allows an authenticated attacker to execute arbitrary commands on the affected system.
Technical Details
The vulnerability is located in the SMB server functionality of the AVTECH DGM1104. It stems from insufficient sanitization of user-supplied input within a specific function related to image processing. An authenticated attacker can inject arbitrary commands by crafting malicious input that is then processed by the SMB server. This injected command is then executed with the privileges of the SMB server process, allowing the attacker to potentially gain full control of the device.
CVSS Analysis
The Common Vulnerability Scoring System (CVSS) provides a standardized way to assess the severity of security vulnerabilities. CVE-2025-57201 has been assigned a CVSS score of 8.8, indicating a high severity vulnerability.
- Base Score: 8.8
- Vector: (Hypothetical example – replace with actual vector) AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
- This high score reflects the potential for significant impact, including complete compromise of confidentiality, integrity, and availability of the affected device. The low attack complexity and the requirement for only low privileges for exploitation contribute to the high score.
Possible Impact
Successful exploitation of CVE-2025-57201 can have severe consequences, including:
- Complete System Compromise: An attacker could gain root or system-level access to the DGM1104 device.
- Data Theft: Sensitive data stored on the device could be accessed and exfiltrated.
- Malware Installation: The device could be used to install malware or other malicious software.
- Denial of Service (DoS): The device’s functionality could be disrupted, rendering it unusable.
- Network Pivot: The compromised device could be used as a launching point to attack other devices on the same network.
Mitigation and Patch Steps
Currently, concrete mitigation steps depend on information from AVTECH.
The following general steps are recommended:
- Contact AVTECH Support: Contact AVTECH support (through the AVTECH website) to inquire about a patch or firmware update to address CVE-2025-57201.
- Network Segmentation: Isolate the DGM1104 device on a separate network segment to limit the potential impact of a successful exploit.
- Strong Passwords: Ensure that the device is configured with strong, unique passwords.
- Disable Unnecessary Services: Disable any unnecessary services running on the device, particularly if they are externally accessible.
- Monitor Network Traffic: Monitor network traffic to and from the device for any suspicious activity.
- Follow Security Best Practices: Implement general security best practices for network-connected devices.
