I have registered yesterday, solve five task and contacted author via email. I have no reply yet, so i put my feelings on this box.

- Tasks checks on ranking and ids are unordered (i mean you solve a task and appear another as solved)
- Challenges are not tested 100%. Can solve with unintended solution or via other challenges.
- Last challenge (latex one) is disabled, could you put some box info about progress to enable or why ?
I- know is hard to put online a set of challenges, but if you do make sure is working ok and is fun.

Thanks

Seems author can't reply to that questions. Get challenges up and running is not easy but it's easy to keep a communication channel if you really care about it (support). Maybe holidays time and this guy is not reading us. Neither private forum nor this channel or via email.

It seems that he tries to solve the things, if you see now all files in /tmp are deleted and user root is connected from 89.x.x.x (Poland) to the vps server.

Maybe don't have time to comment here, but i think he is trying to solve that issue.

Regards

No wonder I couldn't solve that today, even though I have an idea of what to do.

It's also a bit strange that one challenge is designed in a way to give you a free code injection vuln...so you can easily get a limited shell on the server. You are limited by the user, but that's no guarantee for the long term!

Hi,

Thanks for the comments. Yes, some challenges had unintended solutions - all of them except the disabled one should work now. The disabled one will be fixed next week.

I'm sorry for any inconveniences!

The score is quite weird, I got 80% and I got only less than 10% of maximum points... a lot of player has only 1 point too...
