CVE-2025-20017 is a vulnerability identified in Intel(R) oneAPI Toolkit and its component software installers. The core issue stems from an uncontrolled search path used by these installers, which can be exploited by an authenticated user with local access to escalate their privileges on the affected system. Essentially, the installers do not properly validate or restrict the directories from which they load components or dependencies during installation or update processes. This flaw allows a user with limited privileges to manipulate the search path, potentially causing the installer to execute malicious code or load unauthorized components with elevated privileges. The vulnerability requires local access and user interaction, and the attacker must have at least low privileges on the system. The CVSS 4.0 base score of 5.4 (medium severity) reflects the moderate risk posed by this vulnerability, considering the high impact on confidentiality, integrity, and availability if exploited, but also the higher attack complexity and requirement for authentication and user interaction. No known exploits are currently reported in the wild, and no patches or mitigations have been explicitly linked yet. This vulnerability is significant because Intel oneAPI Toolkit is widely used for developing high-performance applications, especially in scientific, engineering, and AI domains, meaning that affected systems could be critical infrastructure or research environments.

For European organizations, the impact of CVE-2025-20017 could be substantial, particularly in sectors relying heavily on Intel oneAPI Toolkit for software development, such as technology firms, research institutions, and industrial automation companies. Successful exploitation could allow an attacker with limited access to gain elevated privileges, potentially leading to unauthorized access to sensitive data, modification or disruption of critical applications, and broader compromise of affected systems. This could result in intellectual property theft, operational downtime, and damage to organizational reputation. Given the toolkit's role in high-performance computing environments, exploitation might also affect the integrity of computational results or AI model training processes, which are critical in research and development contexts. The requirement for local access and user interaction somewhat limits the attack surface but does not eliminate risk, especially in environments where multiple users share systems or where insider threats exist.

To mitigate this vulnerability, European organizations should implement the following specific measures: 1) Restrict local user privileges strictly to the minimum necessary, avoiding unnecessary installation or update permissions for non-administrative users. 2) Monitor and control the directories included in the system PATH and other environment variables to prevent unauthorized modification that could influence installer search paths. 3) Employ application whitelisting and integrity verification mechanisms to detect and block unauthorized or tampered installer components. 4) Isolate development and build environments to trusted users only, reducing the risk of insider exploitation. 5) Regularly audit and monitor system logs for unusual installer activity or privilege escalation attempts. 6) Stay updated with Intel’s security advisories and apply patches promptly once available. 7) Consider using sandboxing or containerization for running installers to limit the scope of potential privilege escalation.
