Local privilege escalation via insecure folder permissions
Published Aug 28, 2025 · Updated Feb 26, 2026
Incorrect folder permissions in Acronis Cyber Protect Cloud Agent before build 40734 allow local users to gain elevated privileges. Acronis identifies insecure permissions on an undisclosed Windows folder but does not publish its path, access-control entries, or the privileged operation that uses its contents. Exploitation requires existing low-privileged local access and grants elevated control over data and services.
