CVE-2025-49760 is classified under CWE-73, which pertains to external control of file name or path. This vulnerability exists in Microsoft Windows 10 Version 1507 (build 10.0.10240.0) within the Windows Storage component. It allows an authorized attacker—meaning the attacker must have some level of legitimate access—to influence file names or paths externally. This manipulation can lead to spoofing attacks over a network, where an attacker could deceive users or systems by presenting misleading file paths or names, potentially facilitating further social engineering or targeted attacks. The vulnerability has a CVSS v3.1 base score of 3.5, indicating low severity. The vector string (AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C) shows that the attack is network-based, requires low attack complexity, privileges, and user interaction, affects confidentiality slightly, and does not impact integrity or availability. No known exploits are currently reported in the wild, and no patches have been released yet, though the vulnerability is officially published and reserved by Microsoft. Given that Windows 10 Version 1507 is an early and now unsupported release, the practical exposure is limited mostly to legacy systems still running this version. The vulnerability's main risk is spoofing, which could be leveraged in phishing or social engineering contexts but does not directly compromise system integrity or availability.

For European organizations, the impact of CVE-2025-49760 is generally low due to the limited severity and the requirement for attacker privileges and user interaction. However, organizations still running Windows 10 Version 1507—often legacy or industrial control systems—may face risks of spoofing attacks that could facilitate phishing or misdirection of users, potentially leading to credential theft or further exploitation. Confidentiality could be marginally affected if spoofed file paths trick users into opening malicious files or disclosing sensitive information. The lack of impact on integrity and availability reduces the risk of system compromise or downtime. Nonetheless, sectors with critical infrastructure or sensitive data should consider the risk of social engineering amplification. The absence of known exploits reduces immediate threat levels, but the presence of a published vulnerability necessitates vigilance. European entities with legacy system dependencies or slower patch cycles are more vulnerable, especially in regulated industries where outdated software remains in use.

1. Upgrade all systems from Windows 10 Version 1507 to a supported and fully patched Windows version to eliminate exposure to this vulnerability. 2. Implement strict access controls to limit privileges, reducing the likelihood that an attacker can gain the necessary authorization to exploit this flaw. 3. Educate users about the risks of spoofed file paths and encourage caution when interacting with unexpected files or network resources. 4. Monitor network traffic and logs for unusual file path requests or anomalies that could indicate attempted spoofing. 5. Apply network segmentation to isolate legacy systems still running vulnerable versions, minimizing exposure to external attackers. 6. Stay informed about Microsoft’s security advisories for any forthcoming patches or mitigations specific to this vulnerability. 7. Employ endpoint protection solutions capable of detecting suspicious file path manipulations or spoofing attempts. 8. Conduct regular security audits focusing on legacy systems to identify and remediate outdated software and configurations.
