Frankenstein using an old InternalBlue Version? #7

Closed MrMatch246 closed 3 years ago

MrMatch246 commented 3 years ago

I tried using the internalBlueMod.py and got following error: Traceback (most recent call last): File "/home/user/frankenstein/internalBlueMod.py", line 1, in <module> import internalblue.cmds ModuleNotFoundError: No module named 'internalblue.cmds' I researched that error and found out that in a previous version of internalblue there was a file cmds.py and a class Cmd that was removed when converting form pwntool to cmd2 for cmd-handling (i guess). Is this easy to fix and if not which is the latest working commit?

Greetings.

Oh, you're right, we switched to cmd2 recently. Should be easy to switch but didn't try it yet. @unixb0y added the ports to cmd2, so I guess this one here could be one of the latest working commits: https://github.com/seemoo-lab/internalblue/commit/68f4a7ef0a76c37c85062533c48be44071e77f7d

I'll do some Frankenstein-related stuff in probably 2-3 weeks and will see if I can fix the root cause :)

I'll try fixing the script later :)

Hi, is there a workaround available in the meantime while this is being fixed? Thanks for your work. :)

Hi, I'm half way through the fix. The interalblue API changed quite a bit so porting was not to straight forward. I gues a valid hotfix would be to use an old version of InternalBlue without cmd2. Sorry for the inconvenience, I'll try to push the fix this week.

I've pushed some changes that fix most of this issue. loadelf and xmitstate should work now again however, there is still a bug with mapmemory that I do not understand right now. I also stumbled across some other bugs, especially one in xmitstate. get_int and set_int from xmit_memory.patch caused an illegal instruction as they were not disabled using patch_return()

Tested it on my machine and loadelf also works for me :)
