#
# Airsensor M520 HTTPD Remote Preauth Denial Of Service and Buffer Overflow PoC
#
# The vulnerability is caused due to an unspecified error in the cgis
# files filter used for configure propierties. This can be exploited by
# sending a specially crafted HTTPS request (necessary authentication),
# which will cause the HTTPS service on the system to crash.
#
# Requisites: "Use DHCP" option interface mark "No"
#
# Examples:
#
# GET https://192.168.100.100/adLog.cgi?%41%41%41 HTTP/1.1
# GET https://192.168.100.100/post.cgi?%41%41%41 HTTP/1.1
