Vulnerability from variot
Stack-based buffer overflow in WellinTech KingSCADA before 3.1.2.13 allows remote attackers to execute arbitrary code via a crafted packet. Authentication is not required to exploit this vulnerability.The specific flaw exists within the protocol parsing code contained in kxNetDispose.dll. The parent service is called AEserver.exe and listens on port 12401. The process performs arithmetic on an user-supplied value used to determine the size of a copy operation allowing a potential integer wrap to cause a stack buffer overflow. An unauthenticated attacker can leverage this vulnerability to execute code under the context of the SYSTEM user. The KingSCADA family of products is a Windows-based monitoring and data acquisition application. WellinTech KingSCADA is prone to a stack-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. KingSCADA versions prior to 3.1.2.13 is vulnerable
