Arbitrary file overwrite via symbolic link following
Published Feb 27, 2025 · Updated Feb 28, 2025
Symbolic link following in Acronis Backup integrations before the listed fixed builds allows local users to overwrite files during home recovery. The home-directory recovery path follows attacker-controlled UNIX symbolic links instead of constraining writes to the intended recovery tree. A low-privileged local user must prepare a symlink before recovery; exploitation changes a chosen file but does not disclose data or interrupt service.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
