CVE-2024-34014

Arbitrary file overwrite via followed recovery symlinks

Published Nov 11, 2024 · Updated Feb 27, 2025

Symlink following in Acronis Backup hosting-panel integrations allows local users to overwrite arbitrary files during recovery. During recovery, the integrations follow attacker-controlled symbolic links instead of confining restored output to its intended path. A local low-privileged user must place the link before recovery; the resulting write can replace files accessible to the recovery process.
