CVE-2024-30069 is a medium-severity vulnerability identified in Microsoft Windows 10 Version 1809 (build 10.0.17763.0), specifically affecting the Windows Remote Access Connection Manager component. The vulnerability is classified as CWE-126, which corresponds to a buffer over-read condition. This type of flaw occurs when a program reads data beyond the boundaries of a buffer, potentially exposing sensitive information from adjacent memory. In this case, the vulnerability could lead to information disclosure, allowing an attacker with limited privileges to access sensitive data that should otherwise be protected. Technically, the vulnerability requires local access (Attack Vector: Local) and low privileges (Privileges Required: Low), but does not require user interaction. The attack complexity is high, indicating that exploitation is not straightforward and may require specific conditions or knowledge. The scope of the vulnerability is unchanged, meaning it affects only the vulnerable component without impacting other system components. The CVSS v3.1 base score is 4.7, reflecting a medium severity level primarily due to the confidentiality impact (high), with no impact on integrity or availability. The Windows Remote Access Connection Manager is responsible for managing dial-up and VPN connections, and a buffer over-read here could potentially leak sensitive information related to network connections or credentials stored in memory. Although no known exploits are currently in the wild, the presence of this vulnerability in an older Windows 10 version that is still in use by some organizations presents a risk that could be leveraged by attackers with local access. Given the lack of a published patch link, it is critical for affected organizations to monitor official Microsoft channels for updates and consider mitigating controls until a patch is available.

For European organizations, the primary impact of CVE-2024-30069 is the potential unauthorized disclosure of sensitive information related to remote access connections. This could include credentials or configuration data that attackers might use to escalate privileges or move laterally within a network. Although exploitation requires local access and is complex, insider threats or attackers who have already gained limited footholds could leverage this vulnerability to gather intelligence and strengthen their position. Organizations relying on Windows 10 Version 1809 in critical infrastructure, government, finance, or healthcare sectors may face increased risk due to the sensitivity of the data potentially exposed. The confidentiality breach could lead to further attacks, data leaks, or compliance violations under regulations such as GDPR. However, since the vulnerability does not affect system integrity or availability, direct disruption of services is unlikely. The medium severity rating suggests that while the vulnerability is not immediately critical, it should be addressed promptly to prevent escalation and exploitation in targeted attacks, especially in environments where local access controls are weak or where legacy systems remain in use.

1. Apply official patches from Microsoft as soon as they become available. Regularly monitor Microsoft security advisories for updates related to CVE-2024-30069. 2. Upgrade affected systems from Windows 10 Version 1809 to a more recent, supported version of Windows 10 or Windows 11, as older versions may no longer receive security updates. 3. Restrict local access to systems running vulnerable versions by enforcing strict access controls, including the use of least privilege principles and multi-factor authentication for local logins. 4. Implement network segmentation to limit the ability of an attacker with local access to move laterally and access sensitive systems. 5. Monitor system logs and network activity for unusual behavior that could indicate attempts to exploit this vulnerability or other local privilege escalation techniques. 6. Conduct regular vulnerability assessments and penetration testing focused on legacy systems to identify and remediate similar weaknesses. 7. Educate IT staff and users about the risks of running unsupported or outdated operating systems and the importance of timely patching.
