Descriptions

The WADashboard component of WebAccess/SCADA Versions 9.0 and prior may allow an attacker to control or influence a path used in an operation on the filesystem and remotely execute code as an administrator.

El componente WADashboard de WebAccess/SCADA Versiones 9.0 y anteriores, puede permitir a un atacante controlar o influir en una ruta usada en una operación en el sistema de archivos y ejecutar código remotamente como administrador

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Advantech WebAccess/SCADA. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed.
The specific flaw exists within the WADashboard component. The issue results from the lack of proper validation of a user-supplied path prior to using it to read and execute code from a file. An attacker can leverage this vulnerability to execute code in the context of Administrator.
