gdbghidra - a visual bridge between a GDB session and GHIDRA

The purpose of gdbghidra is to provide means during interactive debug sessions in gdb to quickly follow the flow in GHIDRA; similar to our gdbida plugin for IDA Pro. gdbghidra is not meant to be a full debugger. Instead, it merely serves as a small helper tool to assist during interactive debug sessions that make use of a mixture of tools. It provides simple means to quickly follow along a gdb debug session in GHIDRA. Also it does not need any dependencies on the Python side.

gdbghidra consists of the following two parts:

data/gdbghidra

Features

Installation

Make a change the ~/.gdbinit configuration file to include the plugin:

source ~/gdb_ghidra_bridge_client.py

To install the plugin in GHIDRA follow these steps:

Now you should see the GDBGhidraPlugin window. You can now configure the listener port using the configuration button and start the server using the refresh button.

Next, configure the gdb stub to connect to gdbghidras's port (either command line or gdbinit):

ghidrabridge 10.0.10.10:2305

Building

To build this plugin using gradle run the following command inside gdbghidra directory

gradle -PGHIDRA_INSTALL_DIR=<PATH_TO_GHIDRA_FOLDER>

This produces a fresh extension zip within the gdbghidra/dist folder.

Development

If you want to build gdbghidra from source using GHIDRA's eclipse environment make sure to add json-simple-1.1.1.jar to the classpath as follows:

Between GHIDRA and GDB a simple JSON message format is spoken which could also be used to connect other tools/debuggers to this GHIDRA plugin.

Notes

Please be aware that this is not considered to be finished. Specifically, the following thoughts are on my mind:
