Local privilege escalation via improper symbolic link handling
Published Aug 31, 2023 · Updated Oct 1, 2024
Privilege escalation in Acronis Cyber Protect Home Office before build 40173 allows local users to gain elevated Windows privileges during recovery. The recovery process improperly follows an attacker-controlled symbolic link, causing a privileged file operation to target a resource outside its intended location. Exploitation requires low-privileged local access, user interaction, and a recovery operation; successful abuse compromises the host account boundary.
