CVE-2023-27391 Explained : Impact and Mitigation

This CVE-2023-27391 article provides detailed information about an improper access control vulnerability found in some Intel(R) oneAPI Toolkit and component software installers before version 4.3.1.493. The vulnerability may allow a privileged user to potentially enable an escalation of privilege via local access.

Understanding CVE-2023-27391

This section will delve into what CVE-2023-27391 is and the impact it may have, along with technical details and mitigation strategies.

What is CVE-2023-27391?

CVE-2023-27391 relates to an improper access control issue present in certain Intel(R) oneAPI Toolkit and component software installers before version 4.3.1.493. The vulnerability could be exploited by a privileged user to achieve an escalation of privilege through local access.

The Impact of CVE-2023-27391

The impact of this vulnerability lies in the potential for a malicious actor with high privileges to exploit the improper access control and escalate their privileges on the affected system. This could lead to unauthorized access to sensitive information, manipulation of data, or disruption of services.

Technical Details of CVE-2023-27391

This section provides a deeper technical insight into the vulnerability, including its description, affected systems, versions, and exploitation mechanism.

Vulnerability Description

The vulnerability in Intel(R) oneAPI Toolkit and component software installers before version 4.3.1.493 involves improper access control, which could be leveraged by a privileged user to facilitate an escalation of privilege locally.

Affected Systems and Versions

The affected product is the Intel(R) oneAPI Toolkit and component software installers, specifically versions before 4.3.1.493. Systems running these vulnerable versions are at risk of exploitation.

Exploitation Mechanism

To exploit this vulnerability, a privileged user needs to have local access to the system running the affected Intel(R) oneAPI Toolkit and component software installers. By taking advantage of the improper access control, the user could elevate their privileges.

Mitigation and Prevention

In response to CVE-2023-27391, proactive measures should be taken to mitigate the risk and prevent potential exploitation. This section outlines immediate steps, long-term security practices, and the importance of patching and updates.

Immediate Steps to Take

To mitigate the risk associated with CVE-2023-27391, users should ensure that access controls are properly configured, limit privileges based on the principle of least privilege, and monitor system activity for any suspicious behavior.

Long-Term Security Practices

Implementing stringent access control policies, conducting regular security audits and assessments, and providing security awareness training to users can strengthen the overall security posture and prevent similar vulnerabilities from being exploited.

Patching and Updates

It is crucial to apply patches and updates provided by Intel promptly. Updating the affected Intel(R) oneAPI Toolkit and component software installers to version 4.3.1.493 or later will help remediate the improper access control vulnerability and enhance the security of the system.
