Description

This module exploits an arbitrary file upload vulnerability found in Advantech WebAccess 8.0.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations
of Advantech WebAccess. Authentication is not required to exploit this vulnerability.

The specific flaw exists within the WebAccess Dashboard Viewer. Insufficient validation within
the uploadImageCommon function in the UploadAjaxAction script allows unauthenticated callers to
upload arbitrary code (instead of an image) to the server, which will then be executed under the
high-privilege context of the IIS AppPool.
