Something about pickles? 🥒🥒🥒

From my very rough notes (thanks Vlad! ;p): "You need to pickle the co-ordinates, then sign them using itsdangerous" (looking at previous labs in the series may help work out how the co-ordinates are normally passed). I had no need for rockyou after picking up the not-so-subtle hint in the following screenshot... ;p

Thanks a lot for this amazing hint autom8on, I think I am almost there but I am still missing something. I skipped the rockyou and followed your hint about the not-so-subtle hint. The correct approach is to create a .py file where i define the coords, pickle it, Signer the secret and obtain the token in b64, am I ok or I am totally lost haha?

Sabrina mentioned in another post. "I would recommend having a look at the Browser Developer Tools: Console and JavaScript Execution lab, as there is some overlap in the tasks. We don't have an offensive lab on Python pickles, but you may find Python: Insecure Deserialization useful, including the further reading linked at the end. Good luck!"In the Insecure Deserialization it mentions "The developers of a GPS fitness tracking application unfortunately implemented the feature to upload jogging routes vulnerable to insecure deserialization attacks, since they decided to use the insecure pickle format. Your task is to remediate this vulnerability using the more secure JSON format."So maybe this can be of help.

Is there another lab we can reference or redo that will assist with the coordinates component?

    Hi sabil10
    I see you have also been burned by the maze. Welcome to the support group 😅
    Hopefully, autom8on, domel44, or jamesstammers might be able to provide some assistance.
    Alternatively, if you read through the thread on this page, you might be able to pick up some clues to help. 🤩

Despite finding the 🥒 (Thanks to autom8on for the prompt in the right direction), I'm stumped on how to get to the endpoint 😩
Any more clues from the kind immersers that have already conquered this maze? 👀

    I'm stuck...
    tried deserialization on both move/submit endpoint.. unable to exploit.
    tried rockyou and both endpoint token .. failed..
    found one endpoint 2257 .. which is asking for secret.. but don't see any parameter to brute force..
    I'm stuck... would appreciate any hints
    TIA

  I'm side-eyeing every single pickle to see if they contain secrets 😣
