En Advantech WebAccess en versiones V8.2_20170817 y anteriores, WebAccess en versiones V8.3.0 y anteriores, WebAccess Dashboard en versiones V.2.0.15 y anteriores, WebAccess Scada Node en versiones anteriores a la 8.3.1 y WebAccess/NMS 2.0.3 y anteriores, se han identificado varias vulnerabilidades de inyección SQL que podría permitir que un atacante revele información sensible del 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 GetNodeList 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.
