CVE-2025-14191 is a buffer overflow vulnerability identified in the UTT 进取 512W device firmware versions up to 1.7.7-171114. The vulnerability arises from improper handling of input in the strcpy function within the /goform/formP2PLimitConfig endpoint. Specifically, the function copies user-supplied input without adequate bounds checking, allowing an attacker to overflow the buffer by sending specially crafted data. This overflow can corrupt memory, potentially enabling remote code execution or denial of service. The attack vector is network-based, requiring no authentication or user interaction, making exploitation straightforward for remote attackers. The vulnerability has been publicly disclosed, and although no known exploits are currently observed in the wild, the exploit code is available, increasing the risk of imminent attacks. The vendor was contacted but has not issued any patches or advisories, leaving devices exposed. The CVSS 4.0 score of 8.7 reflects the vulnerability's high impact on confidentiality, integrity, and availability, with low attack complexity and no privileges or user interaction required. This vulnerability affects devices commonly used in network environments, potentially impacting enterprise and critical infrastructure deployments.

For European organizations, this vulnerability poses a significant risk due to the potential for remote code execution or denial of service on affected UTT 进取 512W devices. Compromise of these devices could lead to unauthorized access to internal networks, interception or manipulation of sensitive data, disruption of network services, and lateral movement within corporate or critical infrastructure environments. Telecommunications providers, enterprises relying on these devices for network connectivity, and industrial control systems using them for communication are particularly vulnerable. The lack of vendor response and patch availability exacerbates the risk, increasing the likelihood of exploitation. Disruption or compromise could impact business continuity, regulatory compliance (e.g., GDPR), and national security interests, especially if these devices are part of critical communication infrastructure.

1. Immediately isolate UTT 进取 512W devices from untrusted networks, especially the internet, to reduce exposure. 2. Disable or restrict access to the /goform/formP2PLimitConfig endpoint if possible, using firewall rules or device configuration. 3. Monitor network traffic for anomalous requests targeting the vulnerable endpoint, employing intrusion detection systems with updated signatures. 4. Implement strict network segmentation to limit the ability of attackers to move laterally if a device is compromised. 5. Where feasible, replace affected devices with alternative hardware from vendors with active security support. 6. Engage with UTT or authorized distributors to demand security updates or patches. 7. Maintain up-to-date asset inventories to identify all affected devices. 8. Conduct regular security assessments and penetration tests focusing on network devices. 9. Educate network administrators about this vulnerability and recommended defensive measures. 10. Prepare incident response plans specifically addressing potential exploitation scenarios involving these devices.
