Overview
This blog post details a critical security vulnerability, identified as CVE-2025-57198, affecting AVTECH SECURITY Corporation DGM1104 devices (specifically FullImg-1015-1004-1006-1003). This vulnerability is a command injection flaw found in the Machine.cgi endpoint. Successful exploitation of this vulnerability allows an authenticated attacker to execute arbitrary commands on the affected device.
Technical Details
The command injection vulnerability exists in the Machine.cgi endpoint of the AVTECH DGM1104. An attacker can leverage this flaw by crafting a malicious input that injects shell commands into the system’s execution process. Since authentication is required, an attacker must first gain valid credentials to exploit this vulnerability. However, once authenticated, the attacker has the potential to gain full control of the device.
The specific input parameter affected by the vulnerability requires further analysis based on the available research detailed in the references.
CVSS Analysis
- CVE ID: CVE-2025-57198
- Severity: HIGH
- CVSS Score: 8.8
- Vector: (This would normally be included, but without the actual vector string, it’s not possible to generate. It’s crucial to include the CVSS vector string for accurate analysis).
A CVSS score of 8.8 indicates a High severity vulnerability. This implies a significant risk, as successful exploitation can lead to complete system compromise, including data theft, system disruption, and potential lateral movement within a network.
Possible Impact
Exploiting CVE-2025-57198 can have severe consequences:
- Complete System Compromise: Attackers can gain complete control over the DGM1104 device.
- Data Theft: Sensitive data stored on or accessible through the device can be stolen.
- System Disruption: Attackers can disrupt the device’s functionality, rendering it unusable.
- Lateral Movement: A compromised device can be used as a stepping stone to attack other systems on the network.
- Malware Installation: The attacker can install malware or backdoors for persistent access.
Mitigation and Patch Steps
Currently, the best course of action is to check for a patch from AVTECH:
- Check for Firmware Updates: Visit the AVTECH website to check for available firmware updates for your DGM1104 device. Apply any available updates immediately.
- Contact AVTECH Support: If no patch is available, contact AVTECH support directly to inquire about their plans to address CVE-2025-57198.
- Network Segmentation: Isolate the DGM1104 device on a separate network segment to limit the potential impact of a successful exploit.
- Strong Passwords: Ensure that strong, unique passwords are used for all accounts on the device. Regularly change passwords.
- Monitor Network Traffic: Monitor network traffic to and from the DGM1104 for any suspicious activity.
- Disable Unnecessary Services: Disable any unnecessary services running on the device to reduce the attack surface.
