TITLE

WellinTech KingView KVWebSvr.dll ActiveX Control Stack Buffer Overflow Vulnerability

DESCRIPTION

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. KingView is a product for building data information service platforms for industrial automation. WellinTech KingView 'KVWebSvr.dll' The ActiveX control handles the parameters of the ValidateUser method with boundary conditions. The remote attacker can exploit the vulnerability to build a malicious WEB page, entice the user to parse, and execute arbitrary code in the application security context. WellinTech KingView ActiveX control is prone to a heap-based buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied input. Failed attacks will likely cause denial-of-service conditions. KingView 6.53 is vulnerable; other versions may also be affected
