CVE-2025-6098 is a critical buffer overflow vulnerability identified in the UTT 进取 750W device, specifically affecting version 5.0 of its firmware. The flaw resides in the strcpy function within the /goform/setSysAdm API endpoint, where improper handling of the passwd1 argument allows an attacker to overflow the buffer. This vulnerability can be exploited remotely without requiring any authentication or user interaction, making it highly accessible to attackers. The buffer overflow can lead to arbitrary code execution, potentially allowing an attacker to take full control of the affected device, compromise its confidentiality, integrity, and availability, or cause denial of service. The vulnerability has a CVSS 4.0 base score of 9.3, reflecting its critical severity, with attack vector network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), and no user interaction (UI:N). The impact on confidentiality, integrity, and availability is high (VC:H, VI:H, VA:H). Although the vendor was notified early, no patch or mitigation has been released, and the exploit details have been publicly disclosed, increasing the risk of exploitation. No known exploits in the wild have been reported yet, but the public disclosure and ease of exploitation make this a significant threat to any organization using the affected product. The UTT 进取 750W is likely a network or industrial device given the API context, and its compromise could lead to broader network infiltration or operational disruption.

For European organizations, the exploitation of CVE-2025-6098 could have severe consequences, especially for those relying on UTT 进取 750W devices in critical infrastructure, industrial control systems, or enterprise networks. Successful exploitation could allow attackers to execute arbitrary code remotely, leading to unauthorized access, data theft, manipulation of sensitive information, or disruption of services. Given the device’s likely role in network management or industrial operations, this could translate into operational downtime, safety risks, and financial losses. The lack of vendor response and absence of patches exacerbate the risk, forcing organizations to rely on compensating controls. The critical nature of the vulnerability and its remote exploitability without authentication make it a prime target for threat actors aiming to compromise European industrial or enterprise environments. Additionally, the public availability of exploit information increases the likelihood of opportunistic attacks, potentially affecting supply chains and service providers using this device.

1. Immediate network segmentation: Isolate all UTT 进取 750W devices from critical network segments and restrict access to the /goform/setSysAdm API endpoint using firewall rules or network access controls to limit exposure. 2. Deploy Web Application Firewalls (WAFs) or Intrusion Prevention Systems (IPS) with custom signatures to detect and block attempts to exploit the strcpy buffer overflow via the passwd1 parameter. 3. Monitor network traffic and device logs for unusual activity targeting the API endpoint, including anomalous requests or repeated failed attempts. 4. If possible, disable or restrict remote management interfaces on the device until a patch is available. 5. Engage with UTT or authorized vendors to request firmware updates or official patches and verify device authenticity to avoid counterfeit or unsupported versions. 6. Implement strict credential management and multi-factor authentication on management interfaces to reduce risk from other attack vectors. 7. Prepare incident response plans specific to this vulnerability, including rapid isolation and forensic analysis procedures. 8. Consider deploying network-level anomaly detection solutions to identify lateral movement or post-exploitation activities stemming from compromised devices. These steps go beyond generic advice by focusing on network-level containment, proactive detection, and operational readiness in the absence of vendor patches.
