How can we find out which CMS a website is using?
Yo man why did you stop posting videos 😭
I'm not really too sure. I wanna get back into uploading eventually but at the moment I haven't really got enough spare time to sit and make videos/work through ctfs etc
@@optionalctf ah cool hope you finish everything peacefully and come back again .. looking forward to it
that while loop for the win hahahahhaha what a match
bro is the ultimate troll💀
Great way to solve this room. Thanks. Just try to go slower in some parts, remember not all of us are as good as you are amigo.
That Seth rogen laugh tho 😂

came here wondering if Go's template package was safe for user input and I've got my answer: absolutely not!
This was a really cool one. LUCKILY no one would ever put a form containing a password field therein and use the method=GET in fact that's really something that should almost be a PHP setting ALLOW_FORM.METHOD_GET.-THROW_EXCEPTION_IF_FORM.METHOD_GET_WITH ANY_FIELD,TYPE_PASSWORD=False,log,diei; /* #default=false (dont build fotm), false, die, loh, warn_info, die, Warn_critcal_but_build_form, alter_method.post*/

I followed you from john, greate channel. Is this first time you do this mission? When you mdae the video…
Why can't I nc to port 2222 on my Linux? But I can nc it with attackbox from TryHackMe :(
check ur iptables or maybe use this command to accept all incoming traffic, it happens to me doing printnightmare room. sudo ufw allow 1:65535/tcp
Where to get that php-reverse-shell.php?
thanks
Also following from John's page, dropping a comment because it's a bit bare around here.. Good quality walkthrough
Really great video mate, learned a lot! :D
The video that brought me to Johnny Hamhands which brought me to THM. It's Optional's fault, everyone :D ♥
dude why do you have like only 5 or 6 CTF walkthroughs on tryhackme, what the heck happen to all your videos on tryhackme room walkthoughs there all gone
All of the walkthroughs I've recorded/released on UA-cam are still there? I think in total there are around 13-15 tryhackme videos with a rough split between walkthrough and King of the hill.
@@optionalctf so wierd I guess for some reason I thought I went to your page a while back and seeing a a ton of THM CTF walkthroughs, that’s my b
Thanks my dude
perfect thank you sir. good work mate, cheers
Good video
Beautiful
Nice video
Excellent video
Love this game
You made it so easy man Thanks for the walkthrough
my favorite youtuber
I'm done with box now, but did you say that the root password wasn't crackable?
Greate explanation i didnt think this way very intersting thank you for the video
Your audio is always too low ! Can you please do something ?
Could be solved by "more" or "less" commands?
Great vid again buddy
Great, vid. Saw all of your writeups :P You earned a subscriber.
I've watched the whole video. I take back my comment about you sounding like John Hammond, lol. But both of you are very good CTF players! How did you go in this CTF?
I just wanna let people know that you didn't even need to know that it was running php because /server-status was disallowed within the robots.txt
You talk like John Hammond lol
I'll take that as a massive compliment! Thank you
ugh yeah i thought of this but when scp failed i discounted sftp hah - gg !
Awesome write-up mate <3, Sorry about making it a shared container at first : / but glad you liked the challenge : )
Aye no worries glad you liked it writeup!
thank you
cool challenge I've actually seen SSRF on a real web screenshot tool before lol
Thanks mate, glad you liked the challenge. Haha.. yep I got inspired from a tool I quite used for web screenshots, tho that one didn't had a SSRF.. or maybe it got fixed.
nice video! thanks for running through your entire thought process it adds a lot
My man just keeps 'em coming.Thanks optional, really appreciate your videos <3.
Amazing video, great job
Damn, biggest brain, just get a sftp shell
another great walkthrough! made it look so easy 😎
great walkthrough! i didnt spend much time on this one, saw something in sshpass man page about race conditions but wasnt sure where to go from there 😸
awsome
Amazing video. Very educative. Am gonna have to try it myself
