Practical IBM MQ Penetration Testing notes

In order to interact with IBM MQ in any way, we need to install IBM MQ Client libraries, available only on IBM website. Account registration will be required to get hands on them.

Step 1: Installing prerequisities

Pre-requisites: IBM MQ Client

1. Download the IBM MQ V9.0.0.4 LTS Clients - the file should be named: 9.0.0.4-IBM-MQC-LinuxX64.tar.gz (9.0.0.4 Client install image for IBM MQ on Linux X86-64) - size: 397MB
2. Extract it to whatever directory.

Using Hard Links to point back to attacker controlled location.

mklink /h C:\Windows\System32\Tasks\tasks.dll C:\Tools\Tasks.dll
Hardlink created for C:\Windows\System32\Tasks\tasks.dll <<===>> C:\Tools\Tasks.dll

This can redirect the search to an arbitrary location and evade tools that are looking for filemods in a particular location.

Looking for WaitForSingleObject call within modern msfvenom generated payload.

---

Abstract

This is a document explaining how to locate WaitForSingleObject(..., INFINITE) within msfvenom's (4.12.23-dev) generated payload and how to fix the payload's glitches. It goes through the analysis of a windows/shell_reverse_tcp payload, touching issues like stack alignment, WaitForSingleObject locating & patching. It has been written when I realised there are many topics on the Offensive-Security OSCE/CTP forums touching problem of finding this particular Windows API. Since RE is one of my stronger FU's I decided to write down my explanation of the subject.
