TITLE

Advantech WebAccess Node BWSCADASoap GetAlarms SQL Injection Information Disclosure Vulnerability

Trust: 0.7

sources: ZDI: ZDI-18-481

DESCRIPTION

In Advantech WebAccess versions V8.2_20170817 and prior, WebAccess versions V8.3.0 and prior, WebAccess Dashboard versions V.2.0.15 and prior, WebAccess Scada Node versions prior to 8.3.1, and WebAccess/NMS 2.0.3 and prior, several SQL injection vulnerabilities have been identified, which may allow an attacker to disclose sensitive information from the host. This vulnerability allows remote attackers to disclose sensitive information on vulnerable installations of Advantech WebAccess Node. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed.The specific flaw exists within the handling of the PointList function in BWMobileService.dll. When parsing the ProjectName parameter, the process does not properly validate a user-supplied string before using it to construct SQL queries. An attacker can leverage this vulnerability to disclose sensitive information under the context of the database. Advantech WebAccess and others are products of Advantech. Advantech WebAccess is a browser-based HMI/SCADA software. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. WebAccess Dashboard is one of the dashboard components; WebAccess Scada Node is one of the monitoring node components. WebAccess/NMS is a suite of web browsers for the Network Management System (NMS). SQL injection vulnerabilities exist in several Advantech products
