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.
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.
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.
WellinTech KingView 6.53 allows remote attackers to execute arbitrary code or cause a denial of service (out-of-bounds read) via a crafted packet to (1) TCP or (2) UDP port 2001.
