TITLE

Advantech WebAccess Node Past Traversal Vulnerability in

Trust: 0.8

sources: JVNDB: JVNDB-2020-005162

DESCRIPTION

Advantech WebAccess Node, Version 8.4.4 and prior, Version 9.0.0. Multiple relative path traversal vulnerabilities exist that may allow a low privilege user to overwrite files outside the application’s control. Advantech WebAccess Node Exists in a past traversal vulnerability.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 vulnerable installations of Advantech WebAccess/SCADA. Authentication is not required to exploit this vulnerability.The specific flaw exists within the implementation of IOCTL 0x0000791e in DATACORE.exe. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. 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. Advantech WebAccess Node could allow a remote malicious user to traverse directories on the system, caused by improper validation of user request. An attacker could send a specially-crafted URL request containing "dot dot" sequences (/../) to overwrite arbitrary files on the system
