    Got user yay; working on root

    @Keroseno said:
    After read the code of the file (you know what file I mean), I found the "forbidden characters".... now the question is, how the hell I find the way to use a script without this characters and get the user prompt so many days in this point...

    Some ppl have already linked to a page which includes a way around it

    Read the "proof of concept" section carefully

    Well, thank you very much, I was checking that before, but really, no idea.... so I found other way much easier.

    User: Got it, as someone already say.... the power of dolar...
    Root: I am CRAZY!!! I am doing all what I can with the s*******l but all what I get is a file with the information inside, also I saw that h*****.s***** is running but not loaded, and that is really strange, but is ridiculous how close I am and I can not get it.... is incredible.... Any hint or a gut to shot myself would be welcome.

  • Rooted. Enjoyable & very educational box. Thanks to @manulqwerty and @Ghostpp7

  • Rooted. hint for the root: If the power of gtof is not working, you need to change the command, change permisions on /root/ should be ok, I was trying "cat" all the time and so many hours to the bin.... thanks to @rbt for the help with the user.

    Rooted. Thanks to all, who posted on this forum. I has read this thread at each time, when have stuck, and each time find the answer.

    Seems, like this box have several solutions. My was a bit dirty, because i noob, but it's work.
    Root reverse shell, made by user reverse shell, made by stable another user reverse shell, made by unstable another user reverse shell.

    HInts:

    Foothold: OWASP 10. I was surprised, when i see power of tool for exploitation this vulun. os-shell for example.

    User: dolar, if not worked, look closer what rights you gives and who.
    Root: Someone on this machine at your service.

    Hope it's not a spoiler.

  • Stuck on getting root flag. Unable to link service due to "Invalid Argument". Anyone can give me a nudge?

  • I am being asked for a password even it says I don't need it, would someone mind helping me?

  • Finally Rooted. Here are my hints:

    Initial hole:
    1. Enumerate as much as u can. You'll find a door in front of a data container and a foothole from the front page which you'll get some keys to open the door.
    2. Observe the version of the container. Google it and you'll get a reverse shell.

    User:
    Honestly, this made me brain-f*cked🤦‍♂️. However, when you enumerate enough, you'll find a neighborhood. Read it carefully and you'll know how to get the user.

    Root:
    It's a little bit tricky. Basic enumeration will help you find out a core-level application that you can run it directly. GTFO will help you.

    Conclusion: I learned a lot from this box. Nice box!

  • rooted. very fun box. thanks for all the help

  • Need some hints for this, I'm using sqlmap on the r****s.php?cod=1, trying to use this to dump the tables or get a shell. Yet everytime I run the tool I get banned for 90 seconds and the scan won't complete, any way around this? Or do I have to do it manually?

  • I am having extreme difficulty with this box and the shell I spawn not properly issuing commands. I have done the whole python and ctrl+z magic to elevate to fully functional shell then I move onto the next step for p***r and now when I issue a simple command such as 'ls' it doesn't do anything. I have been stuck on this damn issue for a week now and cant seem to get anywhere. I have tried numerous methods including socat and retrying various shell methods and still run into the same issue.

  • This is your second shell, isn't it? Use it to create a third one that can be handled in the usual way.

    Try sending your *-da shell to another listener on your attacker machine as p***r

  • Spoiler Removed

  • Use Google and find a page that contains one more character...

  • This was a fun one. First foothold seemed like cheating so I'm looking forward to reading the writeups to see how others did it. Root was tricky but there are quite a few hints that are close to spoilers in this thread.

  • got root nice box !
