CVE-2025-57199 is a command injection vulnerability identified in the NetFailDetectD binary of AVTECH SECURITY Corporation's DGM1104 device firmware versions FullImg-1015-1004-1006-1003. The vulnerability requires attacker authentication, meaning the attacker must have valid credentials to access the device. Once authenticated, the attacker can send specially crafted input to the NetFailDetectD binary, triggering command injection that allows arbitrary command execution on the underlying operating system. This can lead to full device compromise, enabling attackers to manipulate device behavior, exfiltrate sensitive data, or disrupt device functionality. The vulnerability affects embedded firmware used in networked security devices, likely IP cameras or DVRs, which are commonly deployed in surveillance and security monitoring environments. No CVSS score has been assigned yet, and no patches or public exploits are currently available, but the vulnerability has been officially published and reserved by MITRE. The lack of known exploits suggests it may not yet be actively exploited in the wild, but the presence of authenticated command injection is a serious risk. The attack surface is limited to authenticated users, but given the nature of these devices, credential compromise or weak authentication could facilitate exploitation. The vulnerability underscores the importance of secure firmware development and timely patching in IoT and security device ecosystems.

For European organizations, this vulnerability poses a significant risk especially to those relying on AVTECH DGM1104 devices for security surveillance and monitoring. Successful exploitation could allow attackers to gain persistent control over these devices, potentially leading to unauthorized surveillance, data leakage, or disruption of security operations. This could impact critical infrastructure sectors such as transportation, energy, government facilities, and private enterprises that depend on these devices for physical security. The compromise of these devices could also serve as a foothold for lateral movement within enterprise networks, increasing the risk of broader network intrusion. The requirement for authentication reduces the risk somewhat but does not eliminate it, as credential theft or weak password policies could enable attackers. The absence of patches means organizations must rely on compensating controls until updates are available. The impact on confidentiality, integrity, and availability is high, given the ability to execute arbitrary commands and potentially control device behavior.

1. Immediately review and strengthen authentication mechanisms for AVTECH DGM1104 devices, including enforcing strong, unique passwords and disabling default credentials. 2. Restrict network access to these devices using network segmentation, firewalls, and VPNs to limit exposure to trusted users only. 3. Monitor device logs and network traffic for unusual or unauthorized command execution attempts or anomalous behavior. 4. Implement multi-factor authentication if supported by the device or surrounding infrastructure to reduce risk of credential compromise. 5. Regularly audit and update firmware and software from AVTECH as soon as patches addressing this vulnerability become available. 6. Consider deploying intrusion detection/prevention systems that can detect command injection patterns or abnormal device activity. 7. Educate administrators and users on the risks of credential theft and the importance of secure device management. 8. If possible, isolate vulnerable devices from critical network segments until patched. 9. Engage with AVTECH support and security advisories to stay informed about updates and mitigation guidance.
