Hack The Box:Buff(Windows)

 The nmap scan for this machine shows two ports open.

nmap scan

We get a website on port 8080 ,but the login form of this one is not vulnerable to sql injection.

webpage

This page does reveal that its using gym management system and this has an exploit available on searchsploit.

exploit

We can use this exploit simply and specify the target. But we get access to the web shell not the system so we can’t do much here and need to get a reverse shell on our machine.

web shell

From here we can get the user flag.

user flag

From our machine we send the netcat exe file and then use it to get a reverse shell on our system but we need to make sure we have a listener on our machine.

netcat reverse connection

We get an interactive shell on our machine which we can enumerate for priv esc.

interactive shell

When we enumerate we find out that there a port 8888 open on this machine internally .

netstat

After further enumeration we find that there is CloudMe_1112.exe file which is running on this port.

This CloudMe has a buffer overflow vulnerability which is available on searchsploit.

cloudme exploit

But to execute this we need to tunnel so we will use chisel. We will make our system a server and the target a client. On our machine we do this:

chisel server

Now we need to transfer the chisel’s exe file and run a client .

chisel client

We established a connected which we can confirm on our machine.

netstat

Now we just need to generate payload and replace it in the script.

generating payload

Then we just run the script but we need to make sure we have netcat listener on our machine.

running exploit

We get the shell as administrator and we get the root flag.

root flag

Happy hacking!!!!

  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. directory busting 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 ...

  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!!!!
