CVE-2025-14191 is a buffer overflow vulnerability identified in the UTT 进取 512W device firmware up to version 1.7.7-171114. The vulnerability arises from improper handling of input in the strcpy function located in the /goform/formP2PLimitConfig endpoint. Specifically, the strcpy function copies user-supplied input without adequate bounds checking, leading to a buffer overflow condition when the input exceeds the allocated buffer size. This flaw can be exploited remotely over the network without requiring authentication or user interaction, making it highly accessible to attackers. Successful exploitation could allow an attacker to execute arbitrary code, potentially gaining control over the device, or cause a denial of service by crashing the system. The vulnerability has been assigned a CVSS 4.0 base score of 8.7, reflecting its high impact on confidentiality, integrity, and availability, combined with low attack complexity and no required privileges. Although the vendor was contacted early, no patch or mitigation guidance has been provided, and public exploit code has been disclosed, increasing the risk of exploitation. The affected product is primarily used in network environments, possibly including telecommunications or enterprise settings, where device compromise could have cascading effects on network security and operations.

For European organizations, the impact of CVE-2025-14191 could be substantial. The affected UTT 进取 512W devices, if deployed in critical network infrastructure such as telecommunications, enterprise networks, or industrial control systems, could serve as entry points for attackers to gain unauthorized access or disrupt services. A successful exploit could lead to remote code execution, allowing attackers to manipulate device configurations, intercept or redirect network traffic, or launch further attacks within the network. This could compromise sensitive data confidentiality and integrity, disrupt availability of network services, and potentially impact business continuity. Given the lack of vendor response and patches, organizations face increased exposure and must rely on compensating controls. The public availability of exploit code further elevates the risk of opportunistic attacks targeting vulnerable devices. The threat is particularly acute for sectors reliant on stable and secure network infrastructure, including telecommunications providers, government agencies, and large enterprises across Europe.

1. Immediately identify and inventory all UTT 进取 512W devices within the network to assess exposure. 2. Implement network segmentation to isolate vulnerable devices from critical systems and sensitive data. 3. Restrict access to the /goform/formP2PLimitConfig endpoint by applying firewall rules or access control lists limiting management interface exposure to trusted IP addresses only. 4. Monitor network traffic and device logs for unusual activity or exploitation attempts targeting the vulnerable endpoint. 5. Disable or restrict remote management features if not essential to reduce attack surface. 6. Engage with UTT or authorized vendors for any available patches, firmware updates, or official mitigation guidance. 7. Consider deploying intrusion detection/prevention systems (IDS/IPS) with signatures targeting known exploit patterns for this vulnerability. 8. Plan for device replacement or firmware upgrade once a patch is available, prioritizing devices in critical network segments. 9. Educate network administrators about the vulnerability and ensure incident response plans include procedures for this threat. 10. Where possible, implement multi-factor authentication and enhanced logging on management interfaces to detect and prevent unauthorized access.
