Detailed vulnerability description

The vulnerability allows a remote user to delete arbitrary files on the system.

The vulnerability exists due to insecure input validation when processing serialized data. A remote user with a role assigned in the Users and Roles settings on the backup server can connect to remote services and exploit insecure deserialization by sending a serialized temporary file collection, thereby enabling the deletion of any file on the system with service account privileges.
