Published Jan 13, 2023 · Updated Apr 4, 2025

Improper privilege management in Trellix Application and Change Control before 8.3.4 allows local users to bypass execution controls. The vendor record identifies the Windows utilman program as the bypass path but does not disclose the faulty validation or policy decision. A locally logged-in administrator is required, and the record does not identify the commands or follow-on actions possible after the bypass.
