Description Preview

The Intel(R) Computing Improvement Program software before version 2.4.5982 contains a vulnerability related to improper permissions in its installer. This security flaw (CVE-2021-0074) could allow an authenticated user with local access to escalate privileges on the affected system. The vulnerability is classified as CWE-281, which relates to improper preservation of permissions.

Overview

This vulnerability affects the installer component of Intel's Computing Improvement Program software. When the installer runs with elevated privileges, it fails to properly set or maintain secure permissions on certain files or directories. As a result, a local authenticated user could potentially exploit these improper permissions to gain elevated privileges on the system. This type of vulnerability is particularly concerning in multi-user environments where privilege boundaries need to be strictly maintained.

Remediation

To address this vulnerability, users should update to Intel Computing Improvement Program software version 2.4.5982 or later. Intel has released this updated version which corrects the permission issues in the installer. Organizations should prioritize this update on systems where multiple users with different privilege levels have access. If immediate updating is not possible, consider restricting local access to trusted users only until the update can be applied.
