Local privilege escalation via insecure folder permissions
Published Apr 2, 2026 · Updated Apr 2, 2026
Local privilege escalation in Acronis True Image for Windows before build 42902 allows local users to gain elevated privileges. An undisclosed product folder has permissions that permit unsafe local modification; Acronis has not identified the folder, affected files, or writable operation. Exploitation requires low local privileges, user interaction, and additional conditions; success grants elevated control of the host.
