CVE-2025-10169 is a high-severity buffer overflow vulnerability affecting the UTT 1200GW device, specifically versions up to 3.0.0-170831. The vulnerability resides in an unknown functionality related to the /goform/ConfigWirelessBase endpoint, where manipulation of the 'ssid' argument can trigger a buffer overflow condition. This flaw allows an attacker to remotely send crafted input to the device without requiring authentication or user interaction, exploiting the vulnerability over the network. The buffer overflow can lead to arbitrary code execution, potentially allowing an attacker to take full control of the affected device, disrupt its operation, or use it as a pivot point for further attacks within a network. The vulnerability has a CVSS 4.0 base score of 8.7, indicating high severity, with network attack vector, low attack complexity, no privileges or user interaction required, and high impact on confidentiality, integrity, and availability. Despite early notification, the vendor has not responded or issued a patch, and no official fixes are currently available. Although no known exploits are reported in the wild yet, a public exploit has been released, increasing the risk of active exploitation. The UTT 1200GW is a network device, likely used in enterprise or industrial environments, making this vulnerability particularly critical given the potential for widespread network compromise.

For European organizations, this vulnerability poses a significant risk to network security and operational continuity. Exploitation could lead to unauthorized access to sensitive data, disruption of wireless network services, and potential lateral movement within corporate networks. Organizations relying on UTT 1200GW devices for wireless connectivity or network infrastructure could face service outages, data breaches, or be leveraged as entry points for broader cyberattacks. Critical sectors such as manufacturing, telecommunications, and public services that depend on stable and secure network devices may experience operational disruptions. The lack of vendor response and patches exacerbates the threat, forcing organizations to consider alternative mitigations or device replacements. Additionally, the public availability of an exploit increases the likelihood of opportunistic attacks targeting vulnerable devices in Europe, where UTT devices may be deployed in various industries.

Given the absence of vendor patches, European organizations should implement the following specific mitigations: 1) Immediately identify and inventory all UTT 1200GW devices in their environment, focusing on those running affected firmware versions. 2) Restrict network access to the management interfaces of these devices, especially the /goform/ConfigWirelessBase endpoint, by implementing strict firewall rules and network segmentation to limit exposure to untrusted networks. 3) Monitor network traffic for anomalous requests targeting the vulnerable endpoint or unusual SSID configuration attempts that could indicate exploitation attempts. 4) Employ intrusion detection/prevention systems (IDS/IPS) with updated signatures to detect known exploit patterns related to this vulnerability. 5) Where feasible, isolate vulnerable devices from critical network segments or replace them with alternative hardware not affected by this issue. 6) Engage with UTT or authorized resellers to seek firmware updates or official guidance, and consider reporting the issue to national cybersecurity authorities to raise awareness. 7) Implement robust incident response plans to quickly address any signs of compromise related to this vulnerability.
