CVE-2026-1410 is a vulnerability identified in the Beetel 777VR1 device firmware versions 01.00.09 and 01.00.09_55. The flaw resides in an unspecified function within the UART (Universal Asynchronous Receiver/Transmitter) interface component, where authentication mechanisms are missing. This absence of authentication means that an attacker with physical access to the device's UART interface can potentially interact with the device without restriction. The vulnerability does not require any prior authentication, user interaction, or privileges, but the attack complexity is high due to the need for physical access and technical skill to exploit the UART interface. The CVSS 4.0 base score is 5.4 (medium severity), reflecting partial impact on confidentiality, integrity, and availability, with high attack complexity and physical attack vector. The vendor, Beetel, has not responded to vulnerability disclosure, and no patches or mitigations have been released. The exploit code is publicly available, increasing the risk of exploitation despite the difficulty. This vulnerability could allow attackers to manipulate device functions, potentially leading to unauthorized control, data leakage, or device disruption. Given the nature of the UART interface, exploitation likely requires direct hardware interaction, limiting remote exploitation but posing a risk in environments where physical device access is possible.

For European organizations, the impact of CVE-2026-1410 depends largely on the deployment context of the Beetel 777VR1 devices. If these devices are used in telecommunications infrastructure, enterprise networks, or critical systems, an attacker with physical access could bypass authentication controls, potentially leading to unauthorized device control, data compromise, or service disruption. The vulnerability affects confidentiality, integrity, and availability, but the high complexity and physical access requirement reduce the likelihood of widespread exploitation. However, in environments with less stringent physical security—such as branch offices, public access points, or shared facilities—this vulnerability could be exploited by insiders or intruders. The lack of vendor response and absence of patches increase the risk, as organizations cannot rely on firmware updates to remediate the issue. The public availability of exploit code further elevates the threat, especially for targeted attacks. Overall, European organizations should consider this vulnerability a moderate risk, particularly where Beetel 777VR1 devices are deployed in sensitive or critical roles.

1. Enforce strict physical security controls to prevent unauthorized access to devices, including locked server rooms, restricted access cabinets, and surveillance in areas where Beetel 777VR1 devices are installed. 2. Conduct regular physical inspections and audits of network equipment to detect any tampering or unauthorized hardware access. 3. Where possible, disable or restrict UART interface access or physically block UART ports to prevent exploitation. 4. Implement network segmentation to isolate Beetel 777VR1 devices from critical network segments, limiting the impact of any compromise. 5. Monitor device behavior and network traffic for anomalies that may indicate exploitation attempts or unauthorized access. 6. Engage with the vendor or community for updates or unofficial patches and consider alternative hardware if the vulnerability cannot be mitigated. 7. Train staff on the importance of physical security and the risks associated with device tampering. 8. Document and enforce policies for device handling, transport, and maintenance to minimize exposure to physical attacks.
