CVE-2022-22139 is a high-severity vulnerability affecting Intel(R) Extreme Tuning Utility (XTU) software versions prior to 7.3.0.33. The vulnerability arises from an uncontrolled search path issue (CWE-427), where the software does not properly validate or restrict the directories it searches when loading components or libraries. This flaw can be exploited by an authenticated local user to escalate privileges on the affected system. Specifically, an attacker with limited privileges who has local access and can interact with the Intel XTU software could manipulate the search path to load malicious code or libraries, thereby gaining elevated privileges, potentially up to full administrative control. The CVSS 3.1 score of 7.3 reflects a scenario where the attack vector is local (AV:L), attack complexity is low (AC:L), privileges required are low (PR:L), and user interaction is required (UI:R). The impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H), indicating that successful exploitation could lead to complete system compromise. Intel XTU is a utility primarily used for performance tuning and overclocking on Intel-based systems, often installed on desktops and workstations. The vulnerability does not appear to have known exploits in the wild as of the published date, but the potential for privilege escalation makes it a significant risk if left unpatched. The lack of a patch link in the provided data suggests users should verify with Intel for the latest updates and apply version 7.3.0.33 or later to remediate this issue.

For European organizations, this vulnerability poses a substantial risk, especially in environments where Intel XTU is deployed on workstations or desktops used by employees with limited privileges. Successful exploitation could allow attackers or malicious insiders to escalate privileges and gain administrative control, potentially leading to unauthorized access to sensitive data, disruption of critical operations, or deployment of further malware. Industries with high reliance on Intel hardware for performance tuning, such as engineering, research, financial services, and manufacturing, may be particularly vulnerable. The local access requirement limits remote exploitation but does not eliminate risk, as attackers could leverage social engineering or physical access to exploit the vulnerability. Additionally, organizations with bring-your-own-device (BYOD) policies or less controlled endpoint environments may face increased exposure. The high impact on confidentiality, integrity, and availability means that exploitation could result in data breaches, system downtime, or compromise of critical infrastructure components.

European organizations should take the following specific actions to mitigate this vulnerability: 1) Inventory all systems running Intel XTU software and identify versions prior to 7.3.0.33. 2) Immediately update Intel XTU to version 7.3.0.33 or later, obtained directly from Intel's official channels to ensure authenticity. 3) Restrict local user permissions and limit installation of software like Intel XTU to trusted administrators only, reducing the attack surface. 4) Implement application whitelisting to prevent unauthorized or malicious DLLs or executables from loading via manipulated search paths. 5) Monitor endpoint logs for unusual local privilege escalation attempts or suspicious activity related to Intel XTU processes. 6) Educate users about the risks of local privilege escalation and enforce strict physical and logical access controls to prevent unauthorized local access. 7) Employ endpoint detection and response (EDR) solutions capable of detecting anomalous behavior indicative of exploitation attempts. 8) Regularly review and update security policies to ensure timely patch management and vulnerability remediation for all endpoint software.
