Hi Hannah, It is a QNAP NAS TS-239 Pro2. No, the web server does not respond anymore. [~] # x='() { :;}; echo VULNERABLE' bash -c : -sh: bash: command not found [~] # x='() { :;}; echo VULNERABLE' sh -c : VULNERABLE [~] # sh --version GNU bash, version 3.2.0(17)-release (i686-pc-linux-gnu) Copyright (C) 2005 Free Software Foundation, Inc.

Maybe I do a re-install of "something". I am not sure at the moment. It only copies directories and files to it on the weekly base with external disks used to back them up permanently (and partially off-site) If I put the disks somewhere else I do not need the box anymore. It was just a handy box already in place before I started here. Regards Peter
