An attacker on the same network as, or who can otherwise affect network traffic from, an Acronis True Image user can cause the True Image update process to execute arbitrary code with system administrator privileges.
Apply an update
This issue is addressed in Acronis True Image 2017 Build 8058. Although the updates are still checked and downloaded over HTTP, the certificate of the downloaded update is verified.
