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.

Directory traversal vulnerability in WellinTech KingView 6.53 allows remote attackers to read arbitrary files via a crafted HTTP request to port 8001.

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.

Heap-based buffer overflow in WellinTech KingView 6.53 allows remote attackers to execute arbitrary code via a crafted packet to TCP port 555.

Stack-based buffer overflow in WellinTech KingView 6.53 allows remote attackers to execute arbitrary code via a crafted packet to TCP port 555.

Stack-based buffer overflow in an ActiveX control in KVWebSvr.dll in WellinTech KingView 6.52 and 6.53 allows remote attackers to execute arbitrary code via a long second argument to the ValidateUser method.
