Overview
CVE-2025-57199 describes a critical command injection vulnerability discovered in AVTECH SECURITY Corporation’s DGM1104 FullImg-1015-1004-1006-1003. This vulnerability resides within the NetFailDetectD binary. An authenticated attacker can exploit this flaw to execute arbitrary commands on the affected system by providing specially crafted input.
Technical Details
The vulnerability stems from insufficient input validation within the NetFailDetectD binary. When handling specific inputs related to network failure detection, the application fails to properly sanitize user-supplied data before using it in a system command. An attacker with valid credentials can inject malicious commands into the input parameters, leading to arbitrary code execution with the privileges of the NetFailDetectD process.
The specific attack vector involves crafting a malicious input string that includes shell metacharacters or command separators. This allows the attacker to append their own commands to the original command being executed by the application. Successful exploitation allows for complete system compromise.
CVSS Analysis
The Common Vulnerability Scoring System (CVSS) has assigned CVE-2025-57199 a score of 8.8 (High).
This score reflects the following factors:
- Attack Vector: Network
- Attack Complexity: Low
- Privileges Required: High (Authentication Required, but could be bypassed if default credentials are used or leaked)
- User Interaction: None
- Scope: Changed
- Confidentiality Impact: High
- Integrity Impact: High
- Availability Impact: High
The high score is primarily due to the potential for remote, unauthenticated code execution and the severe impact on confidentiality, integrity, and availability.
Possible Impact
A successful exploit of CVE-2025-57199 could have significant consequences, including:
- Complete System Compromise: Attackers can gain full control of the AVTECH DGM1104 device.
- Data Breach: Sensitive data stored on or accessible through the device could be stolen.
- Device Hijacking: The device could be used as a bot in a botnet for malicious activities such as DDoS attacks.
- Lateral Movement: Compromised devices could be used to pivot to other systems on the network.
- Service Disruption: The device’s functionality could be disrupted, leading to loss of security monitoring capabilities.
Mitigation and Patch Steps
To mitigate the risk posed by CVE-2025-57199, the following steps are recommended:
- Apply the Official Patch: Check the AVTECH website (http://avtech.com) for a security patch addressing this vulnerability. Apply the patch as soon as it becomes available.
- Restrict Network Access: Limit access to the DGM1104 device to only authorized users and networks. Implement strong firewall rules to prevent unauthorized access from the internet.
- Strong Passwords: Ensure that strong, unique passwords are used for all accounts on the device. Disable or change any default credentials.
- Monitor Network Traffic: Monitor network traffic for suspicious activity that might indicate exploitation attempts.
- Consider Segmentation: Isolate the DGM1104 device from other critical systems on the network to limit the impact of a potential compromise.
