CVE-2023-23577

Local privilege escalation via uncontrolled search path

Published Aug 11, 2023 · Updated Oct 10, 2024

Uncontrolled search path in Intel ITE Tech consumer infrared drivers before 5.5.2.1 allows local users to elevate privileges. The driver uses an uncontrolled search-path element when locating executable code, allowing code from an attacker-influenced location to be selected first. Intel has not disclosed the affected module or search order; exploitation requires authenticated local access, user interaction, and high-complexity conditions.
