CVE-2025-54913 is a race condition vulnerability classified under CWE-362, affecting the Windows UI XAML Maps MapControlSettings component in Microsoft Windows 10 Version 1809 (build 10.0.17763.0). The vulnerability arises from improper synchronization when multiple threads concurrently access shared resources, leading to a state where an attacker with local authorized access can manipulate the execution flow to escalate privileges. This flaw allows an attacker to gain elevated system privileges, potentially compromising system confidentiality, integrity, and availability. The vulnerability has a CVSS v3.1 base score of 7.8, indicating high severity, with an attack vector requiring local access (AV:L), high attack complexity (AC:H), and low privileges (PR:L). No user interaction is needed (UI:N), and the scope is changed (S:C), meaning the vulnerability can affect resources beyond the initially vulnerable component. Although no public exploits are known at this time, the vulnerability poses a significant risk to systems still running this older Windows 10 version, which is common in legacy enterprise environments. The lack of patch links suggests that either a patch is pending or must be obtained through official Microsoft channels. The race condition could be exploited by an attacker to execute code with elevated privileges, potentially allowing full control over the affected system. This vulnerability is particularly concerning because it affects a core Windows component related to UI and mapping services, which are widely used in enterprise applications.

For European organizations, the impact of CVE-2025-54913 is substantial, especially for those still operating Windows 10 Version 1809 in production environments. Successful exploitation can lead to local privilege escalation, enabling attackers to bypass security controls and gain administrative access. This can result in unauthorized access to sensitive data, disruption of critical services, and the potential deployment of further malware or ransomware. Organizations in sectors such as finance, healthcare, government, and critical infrastructure are at heightened risk due to the sensitive nature of their data and the potential for operational disruption. The vulnerability's requirement for local access limits remote exploitation but increases the risk from insider threats or attackers who have already gained limited footholds. Given the high severity and scope change, the vulnerability could facilitate lateral movement within networks, escalating the overall risk posture. European entities with legacy systems or delayed patch management practices are particularly vulnerable, potentially leading to compliance issues with regulations such as GDPR if data breaches occur.

To mitigate CVE-2025-54913, European organizations should first verify if they are running Windows 10 Version 1809 (build 10.0.17763.0) and prioritize upgrading to a supported and patched Windows version. If immediate upgrade is not feasible, organizations should apply any available security updates from Microsoft as soon as they are released. In the absence of a direct patch, implement strict local access controls to limit the number of users with local login privileges, especially on systems running the affected version. Employ application whitelisting and endpoint detection and response (EDR) solutions to monitor for unusual privilege escalation attempts or suspicious behavior related to the Maps MapControlSettings component. Regularly audit and restrict administrative privileges to reduce the attack surface. Additionally, enforce network segmentation to contain potential lateral movement following a local compromise. Educate users about the risks of local privilege escalation and insider threats. Finally, maintain robust incident response plans to quickly detect and respond to exploitation attempts.
