CVE-2022-38970 is a vulnerability affecting the ieGeek IG20 hipcam RealServer V1.0, which utilizes the Shenzhen Yunni Technology iLnkP2P protocol for device communication. The core issue lies in the algorithm used to generate device IDs (UIDs), which are intended to uniquely identify devices and facilitate secure connections. However, this algorithm suffers from a predictability flaw, meaning that an attacker can potentially predict or enumerate valid UIDs. This flaw constitutes an Incorrect Access Control vulnerability (CWE-330), where the system fails to properly restrict access to resources based on authentication or authorization. Exploiting this vulnerability, a remote attacker can establish direct connections to arbitrary devices without proper authorization, bypassing intended security controls. The vulnerability has a CVSS 3.1 base score of 6.5, indicating a medium severity level. The vector indicates that the attack can be performed remotely over the network (AV:N), requires high privileges (PR:H), but no user interaction (UI:N), and impacts confidentiality and integrity significantly (C:H/I:H) without affecting availability (A:N). No known exploits are currently reported in the wild, and no patches or vendor advisories are listed, which suggests that mitigation may require custom or manual controls. The vulnerability is significant because it undermines the security model of the device communication protocol, potentially exposing sensitive video streams or device controls to unauthorized parties.

For European organizations, particularly those deploying ieGeek IG20 hipcam devices or other hardware relying on Shenzhen Yunni Technology's iLnkP2P protocol, this vulnerability poses a risk of unauthorized access to surveillance or IoT devices. Such unauthorized access can lead to breaches of confidentiality, including exposure of sensitive video feeds or personal data, and integrity violations, such as manipulation of device settings or firmware. This is especially critical for sectors relying on video surveillance for security, such as critical infrastructure, transportation, healthcare, and corporate environments. The ability for remote attackers to connect directly to devices without user interaction increases the attack surface and potential for espionage, privacy violations, or sabotage. Given the medium severity and the requirement for high privileges, exploitation may be limited to attackers who have already gained some level of network access or credentials, but the predictability of UIDs lowers the barrier for lateral movement or targeted attacks within networks. The lack of patches and public exploits means organizations must proactively assess their exposure and implement compensating controls to prevent unauthorized device access.

1. Network Segmentation: Isolate ieGeek IG20 hipcam devices and other affected IoT devices on separate VLANs or network segments with strict access controls to limit exposure to untrusted networks or users. 2. Access Control Enforcement: Implement strong authentication and authorization mechanisms at the network perimeter and device management interfaces to prevent unauthorized access, including multi-factor authentication where possible. 3. Monitoring and Logging: Enable detailed logging of device connections and monitor for unusual access patterns or connections from unexpected sources that could indicate exploitation attempts. 4. Firmware and Software Updates: Regularly check for vendor updates or patches addressing this vulnerability and apply them promptly once available. 5. UID Randomization: If possible, replace or reconfigure devices to use more secure UID generation algorithms or mechanisms that prevent predictability. 6. Network Traffic Filtering: Use firewall rules or intrusion detection/prevention systems to block unauthorized inbound connections targeting device communication ports associated with iLnkP2P. 7. Vendor Engagement: Engage with device vendors to request security updates or guidance and consider alternative products with stronger security postures if mitigation is not feasible. 8. Incident Response Preparedness: Develop and test incident response plans specific to IoT device compromise scenarios to quickly contain and remediate potential breaches.
