    * Fixed: Secure the uploads (OFBIZ-12080)
   
    2020/08/10 the OFBiz security team received a security report by Harshit Shukla
    <[hidden email]>, roughly it was (quoting part of it to simplify):
   
    <<I have identified a Remote Code Execution (RCE) Vulnerability. The reason
    behind this RCE is lack of file extension check at
    catalog/control/UploadCategoryImage?productCategoryId=CATALOG1_BEST_SELL&pload_file_type=category>>
   
    Using this post-auth RCE in OFBiz demos, Harshit was able to get some AWS
    credentials by uploading a webshell (based on [0]).
    By security, it was then decided by the Infra and OFBiz security teams to shut
    down the demos.
   
    After discussing the elements reported with Mark J Cox (VP of ASF security team)
    we in common decided that no CVE was necessary.
