Local privilege escalation via insecure folder permissions
Published Jun 4, 2025 · Updated Jun 4, 2025
Incorrect folder permissions in Acronis Cyber Protect 16 before build 39938 allow local users on Windows to elevate privileges. Acronis identifies an insecurely permissioned folder but does not disclose its path, the affected component, or the operation that enables escalation. Exploitation requires low-privileged local access and user interaction, and successful abuse can compromise data and system operation on the same host.
