CVE-2025-20106 is a vulnerability identified in Intel's VTune Profiler software and oneAPI Base Toolkits prior to version 2025.0. The root cause is an uncontrolled search path within the software installer that operates in Ring 3 (user application level). This flaw allows a local authenticated user to perform an escalation of privilege attack by exploiting the way the installer searches for and loads components or dependencies. The attack complexity is high, requiring active user interaction and local access, but does not require special internal knowledge. The vulnerability affects confidentiality, integrity, and availability at a high level within the vulnerable system, although it does not extend beyond the compromised system to affect others. The CVSS 4.0 base score is 5.4, reflecting a medium severity rating, with attack vector local, attack complexity high, privileges required low, and user interaction required. No known exploits have been reported in the wild, and no patches were linked at the time of publication. The vulnerability highlights the risk of insecure software installation paths that can be manipulated by adversaries to gain elevated privileges.

The primary impact of this vulnerability is the potential for privilege escalation by a local authenticated user, which could lead to unauthorized access to sensitive system functions and data. This can compromise the confidentiality, integrity, and availability of the affected system, allowing attackers to execute malicious code with higher privileges, alter or delete critical files, or disrupt system operations. Although the attack requires local access and user interaction, the consequences within targeted environments—such as development workstations or build servers using Intel VTune or oneAPI toolkits—can be significant. Organizations relying on these tools for software development or performance analysis may face risks of insider threats or lateral movement by attackers who have gained initial footholds. The vulnerability does not appear to enable remote exploitation or widespread network impact but poses a serious risk in environments where multiple users share development resources or where endpoint security is weak.

To mitigate this vulnerability, organizations should: 1) Apply updates and patches from Intel as soon as they become available for VTune Profiler and oneAPI Base Toolkits to ensure the uncontrolled search path issue is resolved. 2) Restrict local access to systems running these tools to trusted users only, minimizing the risk of malicious local actors. 3) Implement strict user privilege management, ensuring users operate with the least privilege necessary and avoid running installers or development tools with elevated rights unless absolutely required. 4) Monitor and audit local system activity for unusual installer behavior or privilege escalation attempts. 5) Educate users about the risks of interacting with untrusted files or installers and enforce policies that prevent execution of unauthorized software. 6) Consider application whitelisting and endpoint protection solutions that can detect or block attempts to exploit installer search path vulnerabilities. 7) Review and harden software installation procedures to avoid reliance on insecure search paths or environment variables that can be manipulated by attackers.
