Vulnerability description:
An unauthorized access of database fields data can be done with help of SQL-injection exploitation. Moreover, it can helps attacker to bypass authorization without any password validation. 
Database structure:
«RTUinfo»: SiteNum, SiteType, Description;
«Alarms»: EventStamp, AlarmState, TagName, Description, Operator, Provider, EventStampUTC;
«BWMInfo»: RTU, SalesLocation, Description, Type, Summ;
«dtproperties»: id, objectid, property, value, uvalue, version;
«FlowData»: Site, iDate, DateTime, Rate, Peak, Average, Total, Lvl;
«sysconstraints»: constid, id, colid, spare1, status, actions, error;
«syssegments»: segment, name, status;
«Users»: UID, Password, AccessLevel.

Given elements of database structure contain various information about connected telemetric devices, users, occurred refusals and alarms, execution course of technological process performance. 

Exploitation method:
User ID = 1' or 1=(select top 1 password from Users)--
Password = blank

Solution:
There is no available security update for now. It is highly recommended not to use default passwords for user authorization. Moreover, additionally you can use ACL lists for allowing access only from trusted hosts. Another additional mesaure of safety is using of Web Application Firewalls (WAF) and IPS/IDS systems in the area where SCADA system is located.
