CVE-2025-6562 is a high-severity OS Command Injection vulnerability (CWE-78) affecting certain Hunt Electronic Hybrid DVR models, specifically the HBF-09KD and HBF-16NK. This vulnerability allows remote attackers who have regular user privileges on the device to inject arbitrary operating system commands, which are then executed with the same privileges as the compromised process. The root cause is improper neutralization of special elements in OS commands, enabling attackers to manipulate input parameters to execute unintended commands on the underlying OS. The vulnerability does not require user interaction and can be exploited remotely over the network, with no authentication required beyond regular user privileges. The CVSS 4.0 base score is 8.7, reflecting the ease of exploitation (low attack complexity), no need for user interaction, and the high impact on confidentiality, integrity, and availability of the affected devices. Hybrid DVRs are often used in surveillance and security monitoring environments, meaning exploitation could lead to unauthorized access to video feeds, manipulation or deletion of recordings, or pivoting into internal networks. Although no known exploits are currently in the wild, the vulnerability's nature makes it a significant risk if weaponized. No patches or mitigations have been published yet, increasing the urgency for affected organizations to implement compensating controls.

For European organizations, the impact of this vulnerability could be substantial, especially for those relying on Hunt Electronic Hybrid DVRs for physical security and surveillance. Exploitation could lead to unauthorized command execution on these devices, potentially allowing attackers to disable or manipulate video surveillance, delete critical footage, or use the DVR as a foothold to launch further attacks within the internal network. This could compromise physical security, violate data protection regulations (such as GDPR) if surveillance data is tampered with or leaked, and disrupt business operations. Sectors such as critical infrastructure, transportation, manufacturing, and government facilities that utilize these DVRs for security monitoring are particularly at risk. The high confidentiality, integrity, and availability impacts could also lead to reputational damage and regulatory penalties if exploited.

Given the absence of official patches, European organizations should immediately audit their environments to identify the presence of affected Hunt Electronic Hybrid DVR models (HBF-09KD and HBF-16NK). Network segmentation should be enforced to isolate these devices from critical internal systems and limit access to trusted administrators only. Implement strict access controls and monitor for unusual command execution or network traffic patterns indicative of exploitation attempts. Disable any unnecessary services or remote management interfaces on the DVRs to reduce the attack surface. Employ network-level protections such as intrusion detection/prevention systems (IDS/IPS) with signatures or anomaly detection tuned to OS command injection patterns. Regularly back up surveillance data to secure, offline storage to prevent data loss. Engage with Hunt Electronic for updates or patches and apply them promptly once available. Additionally, consider replacing vulnerable devices with more secure alternatives if mitigation is not feasible in the short term.
