CVE-2023-32221

Local privilege escalation via installation permission omission

Published Jun 12, 2023 · Updated Jan 3, 2025

Incorrect default permissions in EaseUS Todo Backup 20220111.390 allow local users to elevate privileges during installation. The public CNA record identifies only an installation omission and does not disclose the affected file, directory, service, or permission-setting operation. A low-privileged local account is required; successful exploitation crosses a privilege boundary and grants control over data and system operations.
