Redcross

rooted. took a break from the direct root route and went for user first. this is a great example of some of the lessons you learn from oscp. don’t just attack the first thing you see, and know when to move on to something else. yeah, it might be a longer route, but it might also be easier.

Could anyone nudge me as to how to find the second login page i have the first one and i have done enumeration but not able to find the second one.

That was fun…once I had finally gotten RCE things went quite rapidly, one breadcrumb at a time. I’ve taken the non-BOF route now, but I’m keen to give that a try too.

If anyone needs a nudge in the right direction, feel free to PM me.

went the non-BOF route as well, and just got root. That was a good challenge!

Rooted, a very well made box, felt very realistic throughout the whole way.
My review for this box is that althought not being techically difficult it required some critical thinking in order to get it done, it wasn’t hard when you realize what you have to do. I spend many hours doing stupid things and the answer was in front of me all this time but finally i got there with a little bit of help, thanks @dualfade.

I read there are multiple ways to get root (apart from the binary) but i managed to do only one, i’m interested to know how others did it although having an idea i would like to discuss it further.

These are the kind of boxes we need it had a nice touch of realism and critical thinking :wink:
Now i understand the creators need to spend some time creating machines like these but i would rather spend my time solving something that i would face in a pentest scenario rather than decoding some god forsaken esolang (is that what they’re called?) “Frolic” im looking at you, i was cringy throughout the first part.

Someone can give me a hint on priv escalation? I’ve got a reverse shell with user pe****pe, but I can’t find a proper way to escalate to root. I’ve only found a certain binary but I don’t want to play with Bof and ASLR.

Now that you have access, do some enumeration. Look around at things.
Thats Cool you got that user… I never ended up getting access to that user in particular. Must be multiple routes to make this work lol.

I did the enumeration, but I’m running out of ideas. Is the /usr/bin/python2.7 /root/bin/red*****.py usefull for anything?

I’m currently pretty stuck in the limited shell and have only one way to go: the .c file but I am unsure how to proceed, anyone willing to help me out here?

Rooted without touching the binary :slight_smile:

Rooted here too. This was a hard one, maybe because there are so many paths that you better look for more options before you keep struggling against the same wall for hours. I think that is the key to this box. You need to understand ALL about how this server works. I learned a lot :slight_smile:

Same here. Just rooted it without the “intended” method. There was a lot to absorb with this machine and a lot of little things to watch for. I can’t say I had fun with this one, but I learned a few things.

Rooted. This Box was really awesome. Many different ways to get in and to root :).
If anyone needs help feel free to PM me.

I’m completely stuck on the admin panel for now. Could anyone give me a nudge ?

Again THX for this box. Was awesome but I didn’t like it too much

My Hints

this machine is 2 by 1, to the first part don’t discard the params in POST requests (this will give you RCE)

to get root you need verify app and credentials, enumerate (as usual). When you find the other users, just create yours and give it to him status. Then verify the process executing on the machine and read the forum XD

rooted this amazing box. Did a different way but interested to know how people did it ret2libc way. Feel free to pm me

I have four users, according to the tracks the indicated one is p******e, is it necessary to use brute force to find the password? or try decrypt hash, or just guess it according to the information of the site, if so, some hint

Hey all - ive found the “credentials” and have logged in. Found that the feature is vulnerable to S**i but cant seem to find the right syntax, what usually works for me isnt working. Anybody willing to help me out please PM me :slight_smile:

Tedious, this one! I got backend access, the four accounts and hashes, but I can’t get in to a* other than with the account that gets booted. Still trying things, but process is slow. Blowfish is a ■■■■■■■ to crack. Some tips mention you can guess p*****e creds, but if that’s that case my guessing has been sucking for a day or so. Automated some defaults and some of the data from the backend, no joy yet. Trying to find a way to add data, but I think I need access to a first.

After two days I managed to move on, I have a shell with www, I’m seeing if I can root from this user …

Regarding the hashes there are several ways to move forward, try to break the hash of chr**, it will not take you more than 5 minutes using John or hashcat, when you break the password you will see that it is an important clue, do not forget to check everything I’m not talking about just using gobuster, in this thread several people talk about having found more than one login, the answer to this is in the messages in the database
