An information disclosure vulnerability exists in the User authentication functionality of WellinTech KingHistorian 35.01.00.05. A specially crafted network packet can lead to a disclosure of sensitive information. An attacker can sniff network traffic to leverage this vulnerability.

An integer conversion vulnerability exists in the SORBAx64.dll RecvPacket functionality of WellinTech KingHistorian 35.01.00.05. A specially crafted network packet can lead to a buffer overflow. An attacker can send a malicious packet to trigger this vulnerability.

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.

The KCHARTXYLib.KChartXY ActiveX control in KChartXY.ocx before 65.30.30000.10002 in WellinTech KingView before 6.53 does not properly restrict SaveToFile method calls, which allows remote attackers to create or overwrite arbitrary files, and subsequently execute arbitrary programs, via the single pathname argument, as demonstrated by a directory traversal attack.

The SUPERGRIDLib.SuperGrid ActiveX control in SuperGrid.ocx before 65.30.30000.10002 in WellinTech KingView before 6.53 does not properly restrict ReplaceDBFile method calls, which allows remote attackers to create or overwrite arbitrary files, and subsequently execute arbitrary programs, via the two pathname arguments, as demonstrated by a directory traversal attack.

Buffer overflow in kingMess.exe 65.20.2003.10300 in WellinTech KingView 6.52, kingMess.exe 65.20.2003.10400 in KingView 6.53, and kingMess.exe 65.50.2011.18049 in KingView 6.55 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted packet.

WellinTech KingView 6.5.3 and earlier uses a weak password-hashing algorithm, which makes it easier for local users to discover credentials by reading an unspecified file.
