Homebrew vulnerability analysis and mitigation

CVE-2023-27391 is a security vulnerability affecting Intel(R) oneAPI Toolkit and component software installers before version 4.3.1.493. The vulnerability was disclosed on August 8, 2023, and involves improper access control that could potentially allow privileged users to escalate their privileges through local access (Intel Advisory, NVD).

The vulnerability has been classified as an Improper Access Control (CWE-284) issue. It received a CVSS v3.1 Base Score of 6.7 (MEDIUM) with the following vector: CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H. The scoring indicates that the vulnerability requires local access, low attack complexity, high privileges, and no user interaction, with potential high impacts on confidentiality, integrity, and availability (NVD).

If successfully exploited, this vulnerability could enable privilege escalation through local access. The CVSS scoring indicates high potential impact on system confidentiality, integrity, and availability (NVD).

The vulnerability requires local access and high privileges to exploit, suggesting that an attacker would need significant existing access to the system to take advantage of this vulnerability. The attack complexity is rated as low, indicating that once the necessary access is obtained, the vulnerability is relatively straightforward to exploit (NVD).

Intel has released software updates to mitigate this vulnerability. Users should upgrade to Intel oneAPI Toolkit and component software installer version 4.3.1.493 or later (Intel Advisory).
