- Metasploit Modules Related To CVE-2016-0854

Advantech WebAccess Dashboard Viewer uploadImageCommon Arbitrary File Upload
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.
