You should see the following output: StreamRipper, X64dbg and ERC Background informationĪll processes use memory, regardless of what operating system (OS) they are running on. Click through the breakpoints and the interface should pop up. Instructions for installing the plugin can be found on the Coalfire Github page.įinally, we will need a copy of the vulnerable application (StreamRipper 2.6) which can be found here.In order to confirm everything is working, start X64dbg, File -> Open -> Navigate to where you installed StreamRipper and select the executable. A copy of the ERC plugin for X64dbg as the vulnerable application we will be working with is a 32-bit application you will need to either download the 32-bit binaries or compile the plugin manually. We will need a copy of X64dbg which you can download from SourceForge. A Kali virtual machine will also be useful for payload generation using MSFVenom.
#BUFFER OVERFLOW INSTALL#
This guide was written to run on a fresh install of Windows 7 (either 32-bit or 64-bit should be fine) and as such you should follow along inside a Windows 7 virtual machine. A basic knowledge of assembly and the Windows operating system will be useful, however, it is not a requirement. As this is the first article in this series, we will be looking at an exploit where we have a complete EIP overwrite and ESP points directly into our buffer. In this article we will cover the creation of an exploit for a 32-bit Windows application vulnerable to a buffer overflow using X64dbg and the associated ERC plugin.
