Trust: 1.6

sources: IVD: 6265122d-0d35-44b3-85ea-0c5f7b711a0d // IVD: 19380447-9612-4180-8a2e-efbd7ba08404 // CNVD: CNVD-2020-27432 // CNNVD: CNNVD-202005-313

DESCRIPTION

Advantech WebAccess Node, Version 8.4.4 and prior, Version 9.0.0. An improper validation vulnerability exists that could allow an attacker to inject specially crafted input into memory where it can be executed. Advantech WebAccess Node Exists in a past traversal vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be put into a state. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Advantech WebAccess/SCADA. Authentication is not required to exploit this vulnerability.The specific flaw exists within the implementation of IOCTL 0x0000521e in DATACORE.exe. The issue results from the lack of proper validation of user-supplied data, which can result in a memory access past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of Administrator. Advantech WebAccess is a browser-based SCADA software package for monitoring, data acquisition, and visualization. It is used to automate complex industrial processes when remote operation is required
