CoCalc provides the best real-time collaborative environment for Jupyter Notebooks, LaTeX documents, and SageMath, scalable from individual users to large groups and classes!

Vulnerable Application

This module abuses a known default password in IBM Data Risk Manager. The 'a3user' has the default password 'idrm' and allows an attacker to log in to the virtual appliance via SSH. This can be escalated to full root access, as 'a3user' has sudo access with the default password. At the time of disclosure this was an 0day, but it was later confirmed and patched by IBM. Versions <= 2.0.6.1 are confirmed to be vulnerable.

Vulnerability information

For more information about the vulnerability, check the advisory at: https://github.com/pedrib/PoC/blob/master/advisories/IBM/ibm\_drm/ibm\_drm\_rce.md

Setup

The application is available to download as a Linux virtual appliance from IBM's website. You need to have a valid IBM contract to be able to do so.

Verification Steps

Module defaults work very well, you should just need to set RHOSTS!

Scenarios

A successful exploit will look like this:
