Official description

The vulnerability allows a remote attacker to access sensitive data inside exported packages or obtain up to Remote Code Execution (RCE) with root privileges on the device. The vulnerability can be exploited directly by authenticated users, via crafted HTTP requests, or indirectly by unauthenticated users, by accessing already-exported backup packages, or crafting an import package and inducing an authenticated victim into sending the HTTP upload request.

The underlying weakness: Improper Authentication
