CVE-2022-27187

Local privilege escalation via uncontrolled search path

Published Nov 11, 2022 · Updated Feb 5, 2025

Uncontrolled search path in Intel Quartus Prime Standard Edition before 21.1 Patch 0.02std allows local users to escalate privileges. The vendor identifies an uncontrolled search-path element but does not disclose the affected executable, lookup sequence, or attacker-controlled path. Exploitation requires existing local privileges, user interaction, and high-complexity conditions, and successful abuse grants elevated code execution.
