CVE-2025-15461 identifies a critical buffer overflow vulnerability in the UTT 进取 520W device firmware version 1.7.7-180627. The vulnerability arises from improper handling of the selDateType parameter in the /goform/formTaskEdit HTTP endpoint, where the strcpy function is used without bounds checking. This allows an attacker to send a specially crafted request remotely to overflow the buffer, potentially overwriting adjacent memory and enabling arbitrary code execution. The attack requires no authentication or user interaction, increasing its risk profile. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P) indicates network attack vector, low complexity, no user interaction, and high impact on confidentiality, integrity, and availability. Despite early vendor notification, no patch or official response has been issued, and exploit code is publicly available, increasing the likelihood of exploitation. The vulnerability affects a specific firmware version, suggesting that organizations running this version are at direct risk. The lack of vendor response and patch availability necessitates immediate defensive measures to mitigate potential exploitation.

For European organizations, the impact of CVE-2025-15461 can be severe. Successful exploitation can lead to full system compromise of the affected UTT 进取 520W devices, which may be used in industrial, commercial, or critical infrastructure environments. This could result in unauthorized access to sensitive data, disruption of services, or use of compromised devices as footholds for lateral movement within networks. Given the device’s role, attacks could impact operational technology environments, leading to downtime or safety risks. The remote, unauthenticated nature of the exploit increases the attack surface, especially for organizations exposing management interfaces to untrusted networks. The absence of vendor patches and the public availability of exploits further elevate the risk, potentially leading to targeted attacks or widespread scanning and exploitation campaigns. European entities relying on these devices for network or infrastructure management should consider the vulnerability a significant threat to their cybersecurity posture.

Since no official patch is available, European organizations should implement the following specific mitigations: 1) Immediately restrict network access to the /goform/formTaskEdit endpoint by applying firewall rules or network segmentation to limit exposure to trusted management networks only. 2) Deploy intrusion detection and prevention systems (IDS/IPS) with signatures or heuristics to detect exploitation attempts targeting the selDateType parameter. 3) Conduct thorough inventory and version audits of all UTT 进取 520W devices to identify those running vulnerable firmware 1.7.7-180627. 4) Disable or restrict remote management interfaces if not strictly necessary, or enforce VPN and multi-factor authentication for remote access to reduce attack vectors. 5) Monitor logs and network traffic for anomalous requests to the vulnerable endpoint. 6) Engage with UTT or third-party security vendors for potential unofficial patches or mitigations. 7) Prepare incident response plans for potential exploitation scenarios. 8) Consider device replacement if mitigation is not feasible or risk remains high.
