An attacker could exploit this transitional/temporary user account from the trusted domain to access the Virtual Appliance remotely only when the device is freshly installed and not connected to Mysonicwall.

High impact if exploited, but EPSS currently rates exploitation as unlikely (0.36%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
