According to <https://download.schneider-electric.com/files?p_Doc_Ref=SEVD-2021-194-06&gt; this is a hardcoded password issue in EVlink City / Parking / Smart Wallbox Charging Stations that would grant attackers administrative level control over a EVlink City / Parking / Smart Wallbox Charging Stations web server. These types of devices may not be updated regularly due to the need for them to be running constantly throughout the city, so I can imagine implementing a proper patching strategy will be paramount for ensuring this patch gets applied quickly, as this type of vulnerability could either be used for something simple like just resetting the amount a user has to pay to charge their car, or for gaining further access to city infrastructure, which could be used as a precursor to more targeted attacks.
