The Damn Vulnerable Router Firmware Project
hello , i am a beginner and i take problem now.
wheater can i install the DVRF_v03 by QEMU ??
for when i binwalk -eM DVRF_v03.bin
and there is only a piggy file in the folder, ( i referto the link you given :https://www.praetorian.com/blog/getting-started-with-damn-vulnerable-router-firmware-dvrf-v0.1) and there is somewhere different
Thankyou
I install almost everything recommended, buildroot, binwalk, gdb-multiarch, pwndbg, pwntools, qemu and maybe something more. And my commands are that:
`ubuntu@ubuntu:~/Desktop/DVRF/_DVRF_v03.bin.extracted/squashfs-root$ ./qemu-mipsel-static -L ./ -g 1234 ./pwnable/Intro/stack_bof_01
Usage: stack_bof_01
-By b1ack0wl
sudo chroot . ./qemu-mipsel-static -g 1234 ./pwnable/Intro/stack_bof_01
ubuntu@ubuntu:~/Desktop/DVRF/_DVRF_v03.bin.extracted/squashfs-root$ gdb-multiarch pwnable/Intro/stack_bof_01
(gdb) set architecture mips
(gdb) target remote 127.0.0.1:1234
(gdb) c
(gdb) disass main
`
The results are:
warning: remote target does not support file transfer, attempting to access files from local filesystem. Reading symbols from /home/ubuntu/Desktop/DVRF/_DVRF_v03.bin.extracted/squashfs-root/lib/ld-uClibc.so.0...(no debugging symbols found)...done. 0x7f7b9a80 in _start () from /home/ubuntu/Desktop/DVRF/_DVRF_v03.bin.extracted/squashfs-root/lib/ld-uClibc.so.0 (gdb) c Continuing. [Inferior 1 (Remote target) exited with code 01]
Actually there is an warning and exited, which means that gdb can not attach the "DVRF" process, and I do not know what to do more. Since the blog is no longer exist, could you please tell me sth about it? Thx very much!
Could you give the exp for the heapoverflow vuln, I only know it may be exploited by unlink~~

Hello! Thanks for your anwser last time. This time when i enter a lot of 'A' at the stack_bof_01 beside chroot, the (gdb) c shows "The program is not being run." And when i entered (gdb) file, it shows "No executable file now. No symbol file now." What wrong with my gdb lol.
Hello! For my tasks i want to make this firmware for different platforms. First of all i have got a trouble compiling it using toolchain attached to the project. Here is log file:
I've tried using latest Debian OS and Fedora 11 and the problem is the same
