CVE-2025-60714 is a heap-based buffer overflow vulnerability identified in the Windows Object Linking and Embedding (OLE) component of Microsoft Windows 10 Version 1809 (build 10.0.17763.0). This vulnerability arises from improper handling of memory buffers in the OLE subsystem, which can be exploited by an unauthorized attacker with local access to execute arbitrary code. The flaw is classified under CWE-122, indicating a classic heap-based buffer overflow scenario where memory corruption can lead to control over program execution flow. The vulnerability requires the attacker to have local access and to induce user interaction, such as opening a malicious file or triggering a crafted OLE object, but does not require elevated privileges. The CVSS v3.1 base score is 7.8, reflecting high severity due to the potential for complete compromise of the affected system’s confidentiality, integrity, and availability. No public exploits or patches are currently available, but the vulnerability is officially published and tracked. Given that Windows 10 Version 1809 is an older release, many organizations may still have systems running this version, especially in sectors with strict change management or legacy application dependencies. The vulnerability’s exploitation could lead to execution of arbitrary code in the context of the logged-in user, potentially enabling privilege escalation or lateral movement if combined with other vulnerabilities or misconfigurations.

For European organizations, this vulnerability poses a significant risk to endpoint security, particularly in environments where Windows 10 Version 1809 remains in use. Successful exploitation can lead to full compromise of affected machines, data theft, disruption of services, and potential footholds for further network intrusion. Industries such as manufacturing, healthcare, government, and finance often have legacy systems or slower upgrade cycles, increasing exposure. The requirement for local access and user interaction limits remote exploitation but does not eliminate risk, especially in scenarios involving phishing or insider threats. The high impact on confidentiality, integrity, and availability means that critical data and systems could be compromised, leading to regulatory compliance issues under GDPR and other European data protection laws. Additionally, the lack of a patch at the time of disclosure means organizations must rely on interim mitigations, increasing operational risk.

European organizations should immediately identify and inventory all systems running Windows 10 Version 1809 to assess exposure. Restrict local access to critical systems through strict physical and network access controls, including the use of endpoint protection solutions that enforce application whitelisting and behavior monitoring. Educate users to avoid opening untrusted files or clicking on suspicious links that could trigger malicious OLE objects. Employ enhanced logging and monitoring to detect anomalous local activity indicative of exploitation attempts. Prepare for rapid deployment of official patches once released by Microsoft by testing updates in controlled environments. Consider upgrading affected systems to a supported Windows version with ongoing security updates to eliminate exposure. Additionally, implement least privilege principles and segment networks to limit the impact of potential compromises. Use endpoint detection and response (EDR) tools to identify and contain exploitation attempts early.
