CVE-2024-38028 is a vulnerability classified under CWE-125 (Out-of-bounds Read) found in the Windows Performance Data Helper Library component of Microsoft Windows 10 Version 1809 (build 10.0.17763.0). The vulnerability allows an attacker with authenticated network access to remotely execute code on the affected system. The root cause is an out-of-bounds read condition, which can lead to memory corruption and ultimately enable execution of arbitrary code with high privileges. The CVSS v3.1 base score is 7.2, indicating a high severity level. The attack vector is network-based (AV:N), with low attack complexity (AC:L), but requires privileges (PR:H) and no user interaction (UI:N). The scope remains unchanged (S:U), and the impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H). Although no known exploits have been reported in the wild yet, the vulnerability poses a significant risk due to the potential for remote code execution. The lack of available patches at the time of publication increases the urgency for mitigation. The vulnerability affects a legacy Windows 10 version, which remains in use in various enterprise environments, especially where upgrade cycles are slower due to compatibility or operational constraints.

For European organizations, this vulnerability presents a critical risk to systems still running Windows 10 Version 1809, which may include legacy enterprise environments, industrial control systems, and government infrastructure. Successful exploitation could allow attackers to execute arbitrary code remotely with elevated privileges, potentially leading to full system compromise. This could result in data breaches, disruption of services, and loss of system integrity and availability. Given the network attack vector and no requirement for user interaction, attackers could automate exploitation in targeted attacks. The high impact on confidentiality, integrity, and availability makes this vulnerability particularly dangerous for sectors such as finance, healthcare, energy, and public administration. Organizations relying on Windows 10 1809 should prioritize mitigation to prevent lateral movement and persistent footholds by threat actors.

1. Apply official security patches from Microsoft as soon as they become available to address CVE-2024-38028. 2. If patching is delayed, restrict network access to systems running Windows 10 Version 1809, especially limiting access to the Windows Performance Data Helper Library services. 3. Employ network segmentation to isolate legacy systems from critical infrastructure and sensitive data environments. 4. Monitor network traffic and system logs for unusual activity indicative of exploitation attempts, focusing on authenticated network sessions. 5. Enforce the principle of least privilege to reduce the number of accounts with high-level privileges that could be leveraged in an attack. 6. Plan and accelerate migration from Windows 10 Version 1809 to supported, updated Windows versions to reduce exposure to legacy vulnerabilities. 7. Use endpoint detection and response (EDR) tools to detect anomalous behavior related to memory corruption or code execution attempts. 8. Conduct regular vulnerability assessments and penetration testing to identify and remediate exposure to this and similar vulnerabilities.
