# 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"
