CVE-2025-15428 is a buffer overflow vulnerability identified in the UTT 进取 512W device, specifically in firmware version 1.7.7-171114. The vulnerability arises from improper handling of input in the strcpy function within the /goform/formRemoteControl endpoint. The 'Profile' parameter can be manipulated remotely to overflow the buffer, potentially allowing an attacker to execute arbitrary code or cause a denial of service. The vulnerability is remotely exploitable without requiring user interaction or elevated privileges, making it highly dangerous. The CVSS 4.0 score of 8.7 reflects the ease of exploitation (network vector, low complexity) and the high impact on confidentiality, integrity, and availability. Despite early notification, the vendor has not issued any patches or advisories, and the exploit code has been made public, increasing the risk of exploitation. No known active exploitation has been reported yet. The lack of authentication requirements and the network accessibility of the vulnerable endpoint make this a critical concern for organizations using this device, especially in environments where these devices manage network traffic or critical communications.

For European organizations, this vulnerability poses significant risks including remote code execution, which could lead to full device compromise, unauthorized access to internal networks, data exfiltration, or disruption of network services. The affected device is likely used in networking or telecommunications infrastructure, so exploitation could impact availability and integrity of communications. Critical sectors such as telecommunications providers, government agencies, and enterprises relying on UTT 进取 512W devices for network management or remote control functions are particularly vulnerable. The absence of vendor response and patches increases the window of exposure. Attackers could leverage this vulnerability to establish persistent footholds or launch further attacks within European networks, potentially affecting confidentiality of sensitive data and operational continuity.

Until an official patch is released, European organizations should implement strict network segmentation to isolate UTT 进取 512W devices from untrusted networks, especially the internet. Deploy firewall rules to block access to the /goform/formRemoteControl endpoint or restrict access to trusted management IPs only. Monitor network traffic for anomalous requests targeting this endpoint and implement intrusion detection/prevention systems (IDS/IPS) signatures to detect exploitation attempts. Conduct thorough inventory and auditing to identify all affected devices and upgrade firmware only when a vendor patch becomes available. Consider temporary device replacement or disabling remote management features if feasible. Additionally, organizations should engage with UTT or authorized resellers to demand timely remediation and track threat intelligence feeds for updates on active exploitation or patches.
