Vulnerability from variot
Advantech WebAccess Node, Version 8.4.4 and prior, Version 9.0.0. An out-of-bounds vulnerability exists that may allow access to unauthorized data. Advantech WebAccess Node Exists in an out-of-bounds read vulnerability.Information may be obtained. This vulnerability allows remote attackers to disclose sensitive information on affected installations of Advantech WebAccess/SCADA. Authentication is not required to exploit this vulnerability.The specific flaw exists within the implementation of IOCTL 0x00002722 in ViewSrv.dll. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities 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
