CVE-2024-38107 is a use-after-free vulnerability classified under CWE-416 found in the Windows Power Dependency Coordinator component of Microsoft Windows 10 Version 1809 (build 10.0.17763.0). The vulnerability arises from improper handling of memory, where a previously freed object is accessed, leading to undefined behavior that can be exploited to elevate privileges. The flaw allows an attacker with limited privileges (low-level privileges) to execute code or actions with elevated privileges without requiring user interaction. The CVSS v3.1 score of 7.8 reflects high severity due to the combination of local attack vector, low attack complexity, low privileges required, no user interaction, and high impact on confidentiality, integrity, and availability. The vulnerability was reserved in June 2024 and published in August 2024, with no known exploits in the wild at the time of disclosure. The absence of a patch link suggests that a fix may be forthcoming or in progress. The Power Dependency Coordinator is a system component responsible for managing power dependencies between system components, and exploitation could allow attackers to bypass security controls and gain elevated access to the system. This vulnerability is particularly relevant for organizations still running Windows 10 Version 1809, which is an older, out-of-support version, increasing the risk due to lack of ongoing security updates.

The impact of CVE-2024-38107 is significant for organizations running Windows 10 Version 1809. Successful exploitation allows an attacker with limited privileges to elevate their access rights, potentially gaining administrative control over the affected system. This can lead to unauthorized access to sensitive data (confidentiality breach), modification or destruction of data (integrity compromise), and disruption or denial of critical services (availability impact). Given that the vulnerability requires no user interaction and has low attack complexity, it can be exploited relatively easily by local attackers or malware that has gained initial foothold with limited privileges. This elevates the risk of lateral movement within networks and persistence by threat actors. Organizations relying on legacy Windows 10 systems in critical infrastructure, government, healthcare, finance, and enterprise environments face increased risk of targeted attacks leveraging this vulnerability to escalate privileges and compromise entire systems or networks.

1. Apply official security patches from Microsoft as soon as they become available for Windows 10 Version 1809. Monitor Microsoft’s security advisories closely. 2. If patches are not yet available, restrict access to systems running Windows 10 Version 1809, especially limiting local user accounts with low privileges from executing untrusted code. 3. Implement strict application whitelisting and endpoint protection to prevent exploitation attempts. 4. Monitor system logs and security telemetry for unusual activity related to power management services or privilege escalation attempts. 5. Consider upgrading affected systems to a supported Windows version with active security updates to reduce exposure. 6. Employ network segmentation to limit the ability of attackers to move laterally if initial compromise occurs. 7. Use least privilege principles to minimize the number of users with elevated rights and audit privilege assignments regularly. 8. Educate IT staff about this specific vulnerability and ensure incident response plans include detection and mitigation steps for privilege escalation attacks.
