HackTheBox:Blunder(Linux)

 Lets hit this off with nmap scan.

nmap scan

We see that port 80 is open and certainly that’s where we will start but the site doesn’t have much for us.

port 80

So we need to explore this a bit and do the directory busting for this target.

directory busting

We found the admin page , now again we hit a dead end since we don’t have credentials.

login page

So we do directory busting again.

The other directories are not so interesting but this todo.txt is promising.

todo.txt

First thing, its written that they need to update the CMS which means that this version is definitely vulnerable and the other thing is that this fergus user needs to do something about uploading images. So we have a username but no password.

For password we can brute force our way in but for that we can’t have a random list so we can use cewl tool to generate the wordlist.

custom wordlist using cewl

Now since we know its Bludit ,we should find some exploit which can help us implement this.

Now that we have the credentials we can use them in the upload exploit for bludit.

Upload Exploit

Now here we are www-data , when we explore the file system we find a hash for administrator but the problem is we are unable to crack it.

hash

So we enumerate further and find another user.php which has password hash for user hugo.

password hash

We can easily crack it on crackstation.

cracking the hash

Now we just need to switch user to hugo and get the first flag.

user flag

After this we enumerate sudo and get an exploit for privilege escalation and we easily get the flag.

root flag

Happy Hacking!!!!

  This was an amazing box with lots to learn. So lets start this with nmap scan with this machine. nmap scan Now with this we have a website in which we are not able to access news.php. So lets add megahosting.htb to /etc/hosts . After this when we try to access news.php we are able to do it. website Now the interesting part is the url ,it has file parameter. We can check if this has LFI vulnerability. lfi check This certainly has lfi so we need to see what kind of file might have something important for us. Upon researching about tomcat we get to know that tomcat stores users information in /usr/share/tomcat9/etc/tomcat-users.xml tomcat-users.xml So now we have a username and password and the roles of this user are admin-gui and manager-script. admin-gui is accessible to us but it has nothing to take us forward. So we need to work on manager-script which isn’t accessible directly ,we do directory busting of this directory. directory busting We get manager/text and we search about ...

  The nmap scan for this target shows the open ports and if we perform an aggressive scan we get to know that the target is vulnerable to MS17–010 and MS08–067. nmap scans We have a github  exploit  available for MS08–067. In this exploit we just need to change the payload . So we need to first generate the payload using msfvenom. payload generation We just need to copy and paste the payload in the POC. updating the POC Now we need to open the netcat listener on our machine and run the exploit. netcat connection We got a connection on our machine. And we can easily get the user flag and root flag. Flags Happy Hacking!!!!
