CVE-2023-7007 is an authentication bypass vulnerability identified in the Sciener Gateway G2 device, specifically version 6.0.0. The root cause is the failure of the Sciener server to validate incoming connection requests from the Gateway G2 devices properly. This lack of validation allows an attacker to spoof a legitimate Gateway G2 device and establish a connection with the server. By impersonating the device, the attacker can retrieve the unlockKey field, which is critical for unlocking or controlling the device. The vulnerability is classified under CWE-290 (Authentication Bypass by Spoofing), CWE-287 (Improper Authentication), and CWE-306 (Missing Authentication for Critical Function). The CVSS v3.1 base score is 8.2, reflecting a network attack vector with no required privileges or user interaction, and a high impact on confidentiality due to unauthorized access to sensitive keys. Integrity impact is low to moderate, as the attacker can potentially influence device behavior by using the unlockKey, but availability is not affected. No patches or exploits are currently publicly available, but the vulnerability poses a significant risk to environments relying on these devices for secure access control. The vulnerability could be exploited remotely, making it a critical concern for organizations deploying these devices in smart home or building automation systems.

For European organizations, the primary impact of CVE-2023-7007 lies in the potential unauthorized access to physical premises or controlled environments managed by the Sciener Gateway G2. The unlockKey is a sensitive credential that could allow attackers to bypass physical security mechanisms, leading to breaches of confidentiality and potential physical theft or sabotage. Organizations in sectors such as smart buildings, corporate offices, residential complexes, and critical infrastructure that utilize these devices could face increased risk of intrusion. The integrity of access control systems could be compromised, undermining trust in IoT security deployments. While availability is not directly impacted, the breach of confidentiality and partial integrity loss could have cascading effects on operational security and compliance with European data protection regulations such as GDPR. The lack of authentication validation also raises concerns about the overall security posture of IoT ecosystems within affected organizations, potentially inviting further exploitation or lateral movement by attackers.

1. Immediate mitigation involves isolating the Sciener Gateway G2 devices within segmented network zones to limit exposure to untrusted networks. 2. Implement strict network access controls and firewall rules to restrict inbound connections to the devices only from trusted management servers. 3. Monitor network traffic for anomalous connection attempts or spoofing behaviors targeting the Gateway G2 devices. 4. Enforce multi-factor authentication and device identity verification mechanisms where possible to supplement the device’s native authentication. 5. Engage with the vendor (Sciener) for updates or patches addressing this vulnerability and prioritize their deployment once available. 6. Conduct regular security audits and penetration testing focused on IoT devices and their integration points. 7. Educate security teams and facility managers about the risks of device impersonation and the importance of physical and network security controls. 8. Consider deploying intrusion detection/prevention systems (IDS/IPS) tuned to detect spoofing or unauthorized access attempts on IoT device protocols.
