# Exploit Title: OpenBMCS 2.4 - Create Admin / Remote Privilege Escalation
# Exploit Author: LiquidWorm
# Date: 26/10/2021
OpenBMCS 2.4 Create Admin / Remote Privilege Escalation
Vendor: OPEN BMCS
Product web page: https://www.openbmcs.com
Affected version: 2.4
Summary: Building Management & Controls System (BMCS). No matter what the
size of your business, the OpenBMCS software has the ability to expand to
hundreds of controllers. Our product can control and monitor anything from
a garage door to a complete campus wide network, with everything you need
on board.
Desc: The application suffers from an insecure permissions and privilege
escalation vulnerability. A regular user can create administrative users
and/or elevate her privileges by sending an HTTP POST request to specific
PHP scripts in '/plugins/useradmin/' directory.
Tested on: Linux Ubuntu 5.4.0-65-generic (x86_64)
Linux Debian 4.9.0-13-686-pae/4.9.228-1 (i686)
Apache/2.4.41 (Ubuntu)
Apache/2.4.25 (Debian)
nginx/1.16.1
PHP/7.4.3
