CVE-2025-15428 identifies a critical buffer overflow vulnerability in the UTT 进取 512W device firmware version 1.7.7-171114. The vulnerability resides in the strcpy function handling the 'Profile' parameter within the /goform/formRemoteControl endpoint. Because strcpy does not perform bounds checking, an attacker can send a specially crafted remote request that overflows the buffer, potentially overwriting adjacent memory. This can lead to arbitrary code execution or cause the device to crash, resulting in denial of service. The attack vector is network-based (AV:N), requires low attack complexity (AC:L), and no privileges or user interaction are needed (PR:L, UI:N). The vulnerability impacts confidentiality, integrity, and availability at a high level (VC:H, VI:H, VA:H). Despite the availability of a public exploit, no active exploitation has been reported. The vendor was notified but has not issued any patch or mitigation guidance, leaving devices exposed. This vulnerability is particularly concerning for environments where these devices serve as network access points or control interfaces, as compromise could lead to broader network infiltration or disruption.

For European organizations, exploitation of this vulnerability could result in significant operational disruptions, including unauthorized remote code execution and denial of service on critical network devices. This could compromise the confidentiality and integrity of network traffic and data passing through the affected device. Organizations relying on UTT 进取 512W devices for network connectivity or remote management may face increased risk of lateral movement by attackers, potentially impacting sensitive systems and data. The lack of vendor response and patches exacerbates the risk, as organizations must rely on alternative mitigations. Critical infrastructure sectors such as telecommunications, manufacturing, and government agencies using these devices could experience service outages or data breaches, leading to financial loss, reputational damage, and regulatory penalties under GDPR and other European cybersecurity regulations.

Given the absence of an official patch, European organizations should implement the following specific mitigations: 1) Immediately isolate affected UTT 进取 512W devices from untrusted networks or restrict access to the /goform/formRemoteControl endpoint using network segmentation and firewall rules. 2) Employ intrusion detection/prevention systems (IDS/IPS) with signatures or heuristics to detect and block exploit attempts targeting this vulnerability. 3) Monitor network traffic for anomalous requests containing suspicious 'Profile' parameter payloads indicative of buffer overflow attempts. 4) Where possible, replace or upgrade affected devices to alternative models or firmware versions not impacted by this vulnerability. 5) Implement strict access controls and network authentication to limit exposure of vulnerable devices. 6) Conduct regular vulnerability scanning and penetration testing focused on network devices to identify exploitation attempts. 7) Maintain comprehensive incident response plans to quickly address potential compromises involving these devices. These targeted actions go beyond generic advice by focusing on network-level controls and proactive monitoring tailored to this vulnerability's characteristics.
