#
# CVE-2020-8654 - Discovery module to allows to run arbitrary OS commands
# We were able to run the 'id' command with the following payload in the target field : ';id #'.
#
# CVE-2020-8655 - LPE via nmap NSE script
# As the apache user is allowed to run nmap as root, we were able to execute arbitrary commands by providing a specially crafted NSE script.
# nmap version 6.40 is used and doesn't have the -c and -e options.
#
# CVE-2020-8656 - SQLi in API in getApiKey function on 'username' field
# PoC: /eonapi/getApiKey?username=' union select sleep(3),0,0,0,0,0,0,0 or '
