Local privilege escalation via insecure folder permissions

Published Sep 27, 2023 · Updated Sep 23, 2024

Incorrect folder permissions in Acronis Cyber Protect 15 before build 35979 allow local users to gain elevated Windows privileges. An undisclosed product folder retains access controls that permit unprivileged modification instead of restricting writes to privileged accounts. A local low-privileged account is required; Acronis has not identified the affected folder or published the escalation path.
