WellinTech KingSCADA before 3.7.0.0.1 contains a stack-based buffer overflow. The vulnerability is triggered when sending a specially crafted packet to the AlarmServer (AEserver.exe) service listening on TCP port 12401.

Stack-based buffer overflow in WellinTech KingSCADA before 3.1.2.13 allows remote attackers to execute arbitrary code via a crafted packet.

An unspecified ActiveX control in WellinTech KingSCADA before 3.1.2, KingAlarm&Event before 3.1, and KingGraphic before 3.1.2 allows remote attackers to download arbitrary DLL code onto a client machine and execute this code via the ProjectURL property value.

WellinTech KingSCADA before 3.1.2, KingAlarm&Event before 3.1, and KingGraphic before 3.1.2 perform authentication on the KAEClientManager console rather than on the server, which allows remote attackers to bypass intended access restrictions and discover credentials via a crafted packet to TCP port 8130.
