These Sinapsi devices store hard-coded passwords in the PHP file of the device. By using the hard-coded passwords in the device, attackers can log into the device with administrative privileges. This could allow the attacker to have unauthorized access.

login.php on the Sinapsi eSolar Light Photovoltaic System Monitor (aka Schneider Electric Ezylog photovoltaic SCADA management server), Sinapsi eSolar, and Sinapsi eSolar DUO with firmware before 2.0.2870_2.2.12 establishes multiple hardcoded accounts, which makes it easier for remote attackers to obtain administrative access by leveraging a (1) cleartext password or (2) password hash contained in this script, as demonstrated by a password of astridservice or 36e44c9b64.
