CVE-2025-62218 is a race condition vulnerability categorized under CWE-362, found in the Microsoft Wireless Provisioning System component of Windows 10 Version 1809 (build 10.0.17763.0). The vulnerability arises from improper synchronization when multiple threads or processes concurrently access shared resources, leading to a condition where the system's state can be corrupted or manipulated. An authorized attacker with local access but low privileges can exploit this flaw to elevate their privileges, gaining higher system rights without requiring user interaction. The vulnerability affects confidentiality, integrity, and availability by potentially allowing unauthorized access to sensitive data, modification of system settings, or disruption of system operations. The CVSS 3.1 base score of 7.0 indicates a high severity level, with attack vector limited to local access and requiring high attack complexity, but no user interaction is needed. No public exploits have been reported yet, but the vulnerability's nature makes it a significant risk for environments where Windows 10 Version 1809 is still in use. The lack of available patches at the time of disclosure necessitates proactive mitigation strategies. This vulnerability is particularly concerning for enterprise and critical infrastructure systems that rely on Windows 10 Version 1809, as privilege escalation can lead to broader system compromise.

For European organizations, this vulnerability poses a significant risk especially in sectors relying on Windows 10 Version 1809, including government, finance, healthcare, and critical infrastructure. Successful exploitation could allow attackers to bypass security controls, escalate privileges, and gain unauthorized access to sensitive data or critical system functions. This could lead to data breaches, disruption of services, or further lateral movement within networks. The local access requirement limits remote exploitation but insider threats or attackers who have gained initial footholds could leverage this vulnerability to deepen their control. Given the widespread use of Windows 10 in European enterprises and public sector organizations, the impact could be substantial if not mitigated promptly. Additionally, the vulnerability could be leveraged in targeted attacks against high-value assets or strategic infrastructure, increasing the potential for economic and operational damage.

1. Apply official patches from Microsoft immediately once they become available to address this race condition vulnerability. 2. Until patches are released, restrict local access to systems running Windows 10 Version 1809 by enforcing strict access controls and limiting administrative privileges. 3. Implement application whitelisting and endpoint detection and response (EDR) solutions to monitor for unusual privilege escalation attempts or suspicious process behavior. 4. Conduct regular audits of user accounts and permissions to minimize the number of users with local access rights. 5. Employ network segmentation to isolate critical systems and reduce the risk of lateral movement following local compromise. 6. Educate IT staff and users about the risks of local privilege escalation and encourage reporting of anomalous system behavior. 7. Consider upgrading affected systems to a more recent and supported Windows version where this vulnerability is not present or has been patched. 8. Monitor threat intelligence feeds for any emerging exploit code or attack campaigns targeting this vulnerability to respond swiftly.
