Following this announcement by Lars back in March it is really
troubling to report that we are still hearing of servers being hacked
as a result of this vulnerability.  The most recent case brought to my
attention just over a week ago (a tomcat server running as root with a
dhis2 war file from nov 2016).  The server was collecting tracker
demographic data on patients and was cracked "wide open".

Please do ensure that you respond to these warnings responsibly.
apologies for cross-posting.

Regards
Bob
