CVE-2025-44619: n/a
Tinxy WiFi Lock Controller v1 RF was discovered to be configured to transmit on an open Wi-Fi network, allowing attackers to join the network without authentication.
AI Analysis
Technical Summary
CVE-2025-44619 is a critical vulnerability affecting the Tinxy WiFi Lock Controller v1 RF device. The core issue is that the device is configured to operate on an open Wi-Fi network without any authentication mechanism. This misconfiguration allows any attacker within wireless range to connect to the device's network freely. Once connected, an attacker can potentially interact with the lock controller, which likely controls physical access points such as doors or gates. The vulnerability is classified under CWE-284, indicating an authorization bypass or insufficient access control. The CVSS v3.1 base score is 9.1, reflecting a critical severity due to the network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction needed (UI:N), and high impact on confidentiality and integrity (C:H/I:H) but no impact on availability (A:N). The lack of authentication combined with the ability to join the network means an attacker can fully compromise the confidentiality and integrity of the lock controller’s operations, potentially unlocking doors or manipulating access logs. Although no known exploits are currently reported in the wild, the vulnerability’s nature and ease of exploitation make it a significant risk. No patches or vendor mitigations are currently documented, increasing the urgency for organizations to implement compensating controls. Given the device’s role in physical security, exploitation could lead to unauthorized physical access, theft, or sabotage.
Potential Impact
For European organizations, this vulnerability poses a severe risk to physical security infrastructure. Organizations using Tinxy WiFi Lock Controllers in offices, data centers, warehouses, or critical infrastructure sites could face unauthorized physical entry if attackers exploit this flaw. This could lead to theft of sensitive information, intellectual property, or physical assets, as well as potential safety risks to personnel. The breach of physical access controls may also facilitate further cyber intrusions by allowing attackers to access internal networks directly. Critical sectors such as finance, healthcare, government, and manufacturing are particularly vulnerable due to the high value of their physical and digital assets. Additionally, organizations subject to strict data protection regulations like GDPR could face legal and reputational damage if physical breaches lead to data compromise. The open Wi-Fi configuration also increases the risk of lateral attacks within the organization’s network if the lock controller is connected to internal systems. The absence of authentication and the ease of exploitation amplify the threat, making it a priority for European entities to address promptly.
Mitigation Recommendations
Given the lack of available patches, European organizations should immediately implement compensating controls. First, isolate the Tinxy WiFi Lock Controller on a dedicated, segmented network with strict firewall rules preventing unauthorized access from other internal or external networks. Disable any open Wi-Fi configurations and, if possible, configure the device to operate on a secured Wi-Fi network with strong WPA3 encryption and robust authentication. If device configuration is not possible, physically restrict wireless signal range using shielding techniques or relocate devices to areas with limited external wireless exposure. Implement network monitoring and intrusion detection systems focused on detecting unauthorized connections to the lock controller’s network. Regularly audit physical access logs and correlate with network access logs to detect anomalies. Additionally, consider deploying multi-factor authentication mechanisms for physical access where feasible, and maintain strict physical security policies including surveillance and access control reviews. Engage with the device vendor or supplier to request firmware updates or patches addressing this vulnerability. Finally, educate security and facilities teams about the risks and signs of exploitation related to this vulnerability.
