Overview
CVE-2025-57200 details a critical command injection vulnerability found in AVTECH SECURITY Corporation’s DGM1104 series. Specifically, the vulnerability resides within the test_mail function. An attacker with valid authentication credentials can exploit this flaw to execute arbitrary commands on the underlying system. This vulnerability poses a significant risk to the confidentiality, integrity, and availability of the device and potentially the network it resides on.
Technical Details
The vulnerability stems from improper input sanitization within the test_mail function. By crafting a malicious input, an authenticated user can inject operating system commands into the function’s parameters. The DGM1104 device, failing to adequately validate the input, executes these injected commands with the privileges of the running process.
The specific affected model is FullImg-1015-1004-1006-1003.
CVSS Analysis
Currently, a CVSS score is not available (N/A) for CVE-2025-57200. However, given the nature of a command injection vulnerability, it’s likely to receive a high CVSS score upon evaluation, potentially ranging from 7.0 to 10.0. This is because successful exploitation allows for complete system compromise, depending on the privileges of the user running the vulnerable process.
Possible Impact
The impact of exploiting this vulnerability can be severe. An attacker could:
- Gain full control of the DGM1104 device.
- Access sensitive information stored on the device.
- Modify device configurations.
- Use the compromised device as a pivot point to attack other systems on the network.
- Install malware or backdoors for persistent access.
- Disrupt the normal operation of the device.
Mitigation and Patch Steps
Currently, there is no official patch available from AVTECH. We recommend the following mitigation steps:
- Contact AVTECH Support: Reach out to AVTECH support (avtech.com) directly to inquire about the status of a patch or firmware update addressing this vulnerability.
- Network Segmentation: Isolate the DGM1104 device from critical network segments to limit the potential impact of a successful exploit.
- Monitor Network Traffic: Implement network intrusion detection systems (IDS) or intrusion prevention systems (IPS) to monitor traffic to and from the device for suspicious activity.
- Restrict Access: Limit access to the DGM1104 device to only authorized users and enforce strong password policies.
- Disable Unnecessary Features: Disable any unnecessary features or services on the device to reduce the attack surface.
We will update this post with official patch information as it becomes available.
