# Exploit Title: Ultimate Project Manager CRM PRO 2.0.5 - SQLi Credentials Leakage
# Date: 2020-16-09
# Exploit Author: nag0mez
# Vendor Homepage: https://ultimatepro.codexcube.com/
# Version: <= 2.0.5
# Tested on: Kali Linux 2020.2


# The SQLi injection does not allow UNION payloads. However, we can guess usernames and passwords fuzzing the database.

# which Python could not verify. I added the verify=False parameter to avoid SSL check.
# The lack of verification results in a warning message from Python.
