CVE-2024-14007 identifies a critical authentication bypass vulnerability in the NVMS-9000 firmware developed by Shenzhen TVT Digital Technology Co., Ltd., which is embedded in numerous white-labeled DVR, NVR, and IPC products globally. The flaw resides in the NVMS-9000 control protocol, where the firmware fails to enforce authentication for critical administrative query commands. By sending a single specially crafted TCP payload to the exposed NVMS-9000 control port, an unauthenticated remote attacker can invoke privileged commands such as queryBasicCfg, queryUserList, queryEmailCfg, queryPPPoECfg, and queryFTPCfg. These commands disclose sensitive information including administrator usernames and passwords transmitted in cleartext, network configurations, email settings, PPPoE configurations, and FTP settings. The vulnerability affects all firmware versions prior to 1.3.4. The CVSS 4.0 base score is 8.7 (high severity), reflecting the vulnerability's network attack vector, low attack complexity, no required privileges or user interaction, and high impact on confidentiality. No known exploits have been reported in the wild yet, but the vulnerability's nature allows straightforward exploitation. The exposure of administrative credentials and device configurations can facilitate further attacks such as device takeover, lateral movement, or persistent surveillance compromise. This vulnerability is particularly concerning for environments relying on these devices for security monitoring and critical infrastructure protection.

For European organizations, the impact of CVE-2024-14007 is significant due to the widespread use of Shenzhen TVT's white-labeled DVR, NVR, and IPC devices in surveillance and security systems. Confidentiality is severely compromised as attackers can retrieve administrator credentials and sensitive configuration data, enabling unauthorized access and control over surveillance infrastructure. This can lead to unauthorized surveillance, data leakage, and potential manipulation or disruption of security monitoring. Integrity and availability risks arise if attackers leverage the disclosed credentials to alter device configurations or disrupt services. Critical sectors such as transportation, government facilities, utilities, and corporate campuses that rely on these devices for physical security are at heightened risk. The vulnerability's ease of exploitation without authentication or user interaction increases the likelihood of attacks, potentially leading to large-scale breaches or espionage. Additionally, exposure of network and service configurations can facilitate further network intrusions or lateral movement within organizational networks. The lack of known exploits in the wild currently provides a window for proactive mitigation before widespread exploitation occurs.

1. Immediate firmware upgrade to version 1.3.4 or later, which addresses the authentication bypass vulnerability. 2. Restrict network access to NVMS-9000 control ports by implementing network segmentation and firewall rules to limit exposure only to trusted management networks. 3. Employ network intrusion detection/prevention systems (IDS/IPS) to monitor and block suspicious TCP payloads targeting NVMS-9000 control ports. 4. Conduct thorough audits of all deployed Shenzhen TVT and white-labeled devices to identify vulnerable firmware versions. 5. Change all default and known administrator credentials on affected devices to strong, unique passwords. 6. Disable unused services and protocols on the devices to reduce the attack surface. 7. Implement strict access control policies and monitor device logs for unusual administrative command queries. 8. Coordinate with vendors and suppliers to ensure timely patch deployment and receive security advisories. 9. For critical infrastructure, consider deploying additional layers of physical and network security to mitigate potential device compromise consequences.
