CVE-2025-62208 is a vulnerability identified in Microsoft Windows 10 Version 1809, specifically within the Windows License Manager component. The issue is classified under CWE-532, which pertains to the insertion of sensitive information into log files. This vulnerability allows an authorized attacker with local access and limited privileges to obtain sensitive information by reading log files where such data has been improperly recorded. The vulnerability does not require user interaction and does not affect system integrity or availability, but it compromises confidentiality by exposing potentially sensitive license or system-related information. The CVSS 3.1 base score is 5.5, reflecting a medium severity level, with the vector indicating local attack vector (AV:L), low attack complexity (AC:L), privileges required (PR:L), no user interaction (UI:N), unchanged scope (S:U), high confidentiality impact (C:H), and no impact on integrity or availability (I:N/A:N). No known exploits have been reported in the wild, and no patches have been released as of the publication date. The vulnerability was reserved in early October 2025 and published in November 2025. The affected version is specifically Windows 10 build 17763.0, which corresponds to Version 1809. Given the nature of the vulnerability, an attacker must have local access and some level of privilege to exploit it, limiting the attack surface primarily to insiders or compromised accounts. The flaw arises from improper handling of sensitive data within logging mechanisms, which is a common security oversight that can lead to information leakage if logs are accessible by unauthorized users.

For European organizations, the primary impact of CVE-2025-62208 is the potential leakage of sensitive information stored in Windows License Manager logs. This could include licensing details or other system-related confidential data that might aid attackers in further exploitation or lateral movement within networks. Although the vulnerability does not directly compromise system integrity or availability, the confidentiality breach can facilitate more sophisticated attacks or compliance violations, especially under GDPR regulations that mandate protection of sensitive data. Organizations with many endpoints running Windows 10 Version 1809 are at risk, particularly those with insufficient local access controls or weak privilege management. Insider threats or attackers who have gained limited local access could exploit this vulnerability to escalate their knowledge of the environment. Critical sectors such as finance, healthcare, and government entities in Europe could face increased risk due to the sensitivity of the leaked information and regulatory scrutiny. The absence of known exploits reduces immediate risk, but the medium severity score and potential for information disclosure warrant proactive mitigation.

To mitigate CVE-2025-62208, European organizations should first identify and inventory all systems running Windows 10 Version 1809 (build 17763.0) and assess their exposure. Since no patches are currently available, organizations should restrict local access to affected systems by enforcing strict access controls and applying the principle of least privilege to limit who can read log files. Implementing robust auditing and monitoring of log file access can help detect unauthorized attempts to read sensitive logs. Organizations should also consider isolating or upgrading affected systems to newer Windows versions where this vulnerability is not present. Additionally, encrypting log files or storing them in secure locations with controlled permissions can reduce the risk of unauthorized disclosure. Preparing for vendor patches by maintaining an effective patch management process is critical once updates become available. Training IT staff and users about the risks of local privilege misuse and enforcing strong endpoint security controls will further reduce exploitation chances.
