DVRF - The Damn Vulnerable Router Firmware Project

项目说明

Damn Router Firmware (DVRF) v0.3

Thanks for checking out my project. The goal of this project is to simulate a real world en to help people learn about other CPU architectures outside of the x86_64 space. This project will also help people get into disco new things about hardware.

As of now this firmware is tailored for the Linksys E1550 Device. If you do not have one don't worry! There's also QEMU and I encourage end users to experiment with both en.

Installation

> To Install this binary onto your E1550 simply go to the Firmware Upgrade page () and point the upgrade path to D.bin and click "Upgrade"

Removal || Revert

> To revert back to stock simply na to the main page of DVRF (), Click Browse, Point it to the stock firmware binary, and Click "Upload Firmware"

Getting Started

> You don't have to have a E1550 in order to get started. The following link will show you how to get started with D QEMU to emulate the en -

Source Code for pwnables

> Feel free to take a look at the source code for the pwnables so you can get a better understanding MIPS assembly. Please note that the compiled binaries used gcc flag -O0 to turn off compiler optimizations.

Compiling your own D

> Execute merge_and_compile.sh and if the tar ball was successfully made you can run clean.sh to remove the 00* files.
> To compile just extract the TAR file and run make.sh and make sure to update toolchain.sh to the path of your toolchain
> The toolchain is located under ./projects/hnd/tools/linux/hndtools-mipsel-linux-uclibc-4.2.3/bin.
> Also note that the target linux is 2.6 so you can either compile it on a 2.6 box like Fedora Core 11 or try compiling with the linux 2.6 headers.

=======

#### Fixes
* Replaced execve("/bin/sh",0,0) with system("/bin/sh -c")
* Due to "jr RA" I added exit(0) after the system() call to prevent infinite loops.
* Extended buffer size on pwnable challenges that require shellcode.

#### Notes
* DO NOT HAVE THE WAN PORT PLUGGED IN WHEN INSTALLING OR RUNNING THIS!!!
* UART access is needed in order to execute the pwnable binaries.
* WiFi is disabled, only the ethernet ports are a.
* Encoder pwnable to be released in v04.
