The remote host is running FortiOS version 5.x prior to 5.4.11, 5.6.x prior to 5.6.8 or 6.x prior to 6.0.3. It is, therefore, affected by a remote code execution vulnerability that allows an authenticated, regular user to change the routing settings of the device via connecting to the ZebOS component.
