CVE-2024-38028 is a high-severity vulnerability identified in the Microsoft Windows Performance Data Helper Library affecting Windows 10 Version 1809 (build 10.0.17763.0). The vulnerability is classified as an out-of-bounds read (CWE-125), which occurs when the software reads data outside the boundaries of allocated memory. This flaw can be exploited remotely to achieve remote code execution (RCE), allowing an attacker to execute arbitrary code on the affected system with elevated privileges. The CVSS 3.1 base score of 7.2 reflects a high severity level, with an attack vector that is network-based (AV:N), low attack complexity (AC:L), but requiring high 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 are currently reported in the wild, the vulnerability poses a significant risk due to the potential for complete system compromise. The Windows Performance Data Helper Library is a core component used for performance monitoring and diagnostics, making this vulnerability particularly critical as it could be leveraged to disrupt system operations or gain persistent access. The lack of available patches at the time of publication increases the urgency for affected organizations to implement interim mitigations and prepare for prompt patch deployment once available.

For European organizations, this vulnerability presents a substantial risk, especially for those still operating legacy systems such as Windows 10 Version 1809, which despite being out of mainstream support, may remain in use in industrial, governmental, or enterprise environments. Exploitation could lead to unauthorized remote code execution, resulting in data breaches, disruption of critical services, and potential lateral movement within networks. Confidentiality, integrity, and availability of sensitive data and systems could be severely compromised. Sectors such as finance, healthcare, manufacturing, and public administration, which often rely on legacy Windows systems for operational continuity, are particularly vulnerable. The high impact on system integrity and availability could lead to operational downtime, regulatory non-compliance, and reputational damage. Additionally, the requirement for high privileges to exploit the vulnerability suggests that attackers may need initial access or insider capabilities, but once achieved, the consequences could be severe.

Given the absence of an official patch at the time of reporting, European organizations should prioritize the following mitigations: 1) Conduct an immediate inventory to identify all systems running Windows 10 Version 1809 and assess their exposure to network-based attacks. 2) Restrict network access to vulnerable systems by implementing strict firewall rules and network segmentation to limit exposure to untrusted networks. 3) Enforce the principle of least privilege to minimize the number of users and processes with high-level privileges, reducing the attack surface. 4) Monitor system and network logs for unusual activity related to the Performance Data Helper Library or unexpected remote code execution attempts. 5) Apply enhanced endpoint detection and response (EDR) solutions capable of detecting anomalous behavior indicative of exploitation attempts. 6) Prepare for rapid deployment of official patches once released by Microsoft, including testing in controlled environments to ensure compatibility. 7) Educate IT staff about the vulnerability specifics to recognize potential exploitation indicators and respond promptly. 8) Consider upgrading affected systems to supported Windows versions where feasible to benefit from ongoing security updates.
