CVE-2025-15090 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 the 'timestart' parameter in the strcpy function within the /goform/formConfigNoticeConfig endpoint. Since strcpy does not perform bounds checking, an attacker can supply an overly long 'timestart' argument to overflow the buffer, potentially overwriting adjacent memory. This flaw can be exploited remotely without requiring authentication or user interaction, making it highly accessible to attackers. Successful exploitation could allow arbitrary code execution, leading to full system compromise, data leakage, or denial of service. The CVSS 4.0 base score is 8.7 (high), reflecting the vulnerability's network attack vector, low complexity, no privileges or user interaction needed, and high impact on confidentiality, integrity, and availability. Although no exploits have been observed in the wild, public exploit code availability increases the risk of imminent attacks. The vulnerability affects a specific firmware version of a networking device commonly used in certain markets, emphasizing the need for targeted mitigation and patching efforts.

For European organizations, this vulnerability poses a significant risk, particularly for those relying on UTT 进取 512W devices in their network infrastructure. Exploitation could lead to unauthorized remote code execution, allowing attackers to gain control over affected devices. This can result in data breaches, network disruption, or pivoting to other internal systems. Critical sectors such as telecommunications, government networks, and industrial control systems could face operational outages or espionage. The lack of required authentication and user interaction lowers the barrier for attackers, increasing the likelihood of exploitation. Additionally, the public availability of exploit code may accelerate attack campaigns targeting vulnerable devices across Europe. The impact extends beyond individual organizations to national infrastructure stability and data protection compliance obligations under GDPR.

1. Immediate identification and inventory of all UTT 进取 512W devices running firmware version 1.7.7-171114 within the network. 2. Apply vendor-provided firmware updates or patches as soon as they become available; if no patch exists, contact the vendor for guidance or consider device replacement. 3. Implement network segmentation to isolate vulnerable devices from critical systems and limit exposure to untrusted networks, especially the internet. 4. Deploy web application firewalls (WAFs) or intrusion prevention systems (IPS) with custom rules to detect and block malicious payloads targeting the /goform/formConfigNoticeConfig endpoint and suspicious 'timestart' parameter values. 5. Monitor network traffic and device logs for anomalous requests or signs of exploitation attempts. 6. Restrict remote management access to trusted IP addresses and enforce strong authentication mechanisms where possible. 7. Conduct regular security assessments and penetration testing focusing on network devices to identify similar vulnerabilities. 8. Educate IT and security teams about this specific vulnerability and response procedures to ensure rapid mitigation.
