CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Advantech WebAccess versions 9.02 and prior are vulnerable to a heap-based buffer overflow, which may allow an attacker to remotely execute code.

Remedy

In order to address the heap-based buffer overflow vulnerability, Advantech recommends users directly add the remote access code to avoid being attacked by unknown requests. This is the remote access code established during installation of the Advantech WebAccess SCADA software (SCADA node, project node, or OPC Service) on the OPC Server computer. The access code you enter here must match the remote access code established during installation on the OPC Server. This prevents unauthorized users from accessing the OPC Server data using the Advantech WebAccess SCADA OPC Service. If you have forgotten the remote access code using during software installation on the OPC Server node, you have two options: Re-install the Advantech WebAccess SCADA software on the OPC Server node to change it and edit it to match in your database. Edit the BWSERVER.INI file on the OPC Server node and edit it to match in your database using UPDATE.

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Advantech WebAccess Node. Authentication is not required to exploit this vulnerability. The specific flaw exists within the implementation of the 0x27DC IOCTL in the webvrpcs process. The issue results from the lack of proper validation of a user-supplied value prior to dereferencing it as a pointer. An attacker can leverage this vulnerability to execute code in the context of Administrator.
