Canape

Could someone with a foothold PM me? I need a nudge on how to exploit Couch + the link I found in the source code. I’m lost on what to do with it.

You need to research a bit more on how the service is working in the background to exploit. If you don’t already have the necessarily files, you may need to enumerate a bit more as well.

Sorry, I don’t have user or even a shell yet. I’m still struggling with just understanding what I have. Do you mean enumerate the site directory, or did I accidentally give the impression I have a shell.

Pwned user. This machine is cool af. Feel free to PM me too for nudges too.

Hint, (as seems to be the case often) a stable RCE is almost as useful as a shell – I could get everything to pwning user without a shell. Something that can execute commands and give back output is useful enough in this case.

… and root… Can confirm root is quite easy after pwning user.

i receive UnpicklingError: pickle data was truncated or BadPickcleget 111, I’m stuck. hint?

Spoiler Removed - Arrexel

Finally got shell. Not rooted yet, but I’m happy to nudge people still working on the initial foothold

Finally got root. Cool machine, thanks for the hints. If anyone needs a hint, you can PM me.

I have found all that I believe from remote enumeration and I have a few things to track down, but spent a lot of time so far with no luck; currently in a pickle trying to figure it all out. Please PM me if you can help me talk it out?

rooted! learned a lot :slight_smile:

Need some help on getting shell. I understand the exploit, have re-created it on my own machine and have even been able to pop a reverse shell on my own machine but never on Canape.

To everyone stuck at their pickled payload not working when submitted to the site: try using a popular http library for the submission of your pickled code. Copy & pasting the payload from the terminal + bad url encoding fucks up the payload, with the mentioned library it worked flawlessly.

Great box, enjoyed it all the way through lol

Is anyone else receive Bad Request on check endpoint ??

NVM got it :slight_smile:

Finally rooted. Feel free to PM me for vague nudges :wink:

rooted!
Need a nudge? PM!

Rooted :slight_smile:
Good and learn many new things

Lost getting the initial foothold. Anybody can give me a nudge??
